types

import "oblikovati.org/api/types"

Package types holds the shared vocabulary of the Oblikovati API: enums, stable identifiers, and value/option structs with no behavior. Both the GPL implementation and add-ins use these as a common, Apache-2.0 type currency so the same concepts (a document kind, a parameter kind, a 2D point) are named once.

Types here are pure data — no dependency on the implementation, no methods that touch live model state. The richer behavioral surface lives in oblikovati.org/api/contract (in-proc Go interfaces) and oblikovati.org/api/wire (the JSON contract).

Constants​

Per-document-type on-disk extensions (ADR-0034). Each document kind carries its own user-facing extension so the OS, file dialogs, and the reference graph can identify a file's kind *before* its manifest is read, and so assemblies and drawings name their referenced files unambiguously. This supersedes the single ".obk" package extension (ADR-0020 amended): the manifest's documentType stays the canonical identity — the extension mirrors it and must agree.

const (
    // PartFileExtension is the extension for a part document (DocumentPart).
    PartFileExtension = ".opd"
    // AssemblyFileExtension is the extension for an assembly document (DocumentAssembly).
    AssemblyFileExtension = ".oad"
    // DrawingFileExtension is the extension for a drawing document (DocumentDrawing).
    DrawingFileExtension = ".odd"
    // PresentationFileExtension is the extension for a presentation document (DocumentPresentation).
    PresentationFileExtension = ".ord"
    // ProjectFileExtension is the extension for a design-project file. A project is
    // NOT a document (it has no DocumentType) — it is the portable search-path
    // config that resolves a document's referenced files (architecture core/05).
    ProjectFileExtension = ".opj"
)

Well-known work-feature references — the part's static origin coordinate frame, valid as entries in a work-plane create request's Refs (e.g. the base plane of an offset). Other references (to user work planes, or a B-rep face) come back from workPlanes.list and model selection.

const (
    WorkRefCenter  = "origin/point/center"
    WorkRefXAxis   = "origin/axis/x"
    WorkRefYAxis   = "origin/axis/y"
    WorkRefZAxis   = "origin/axis/z"
    WorkRefXYPlane = "origin/plane/xy"
    WorkRefXZPlane = "origin/plane/xz"
    WorkRefYZPlane = "origin/plane/yz"
)

ContinuityInfinite is the Continuity() order reported by analytic geometry, which is smooth to every order (C∞).

const ContinuityInfinite int = 1 << 30

ReservedSubTypePrefix marks built-in sub-type ids; client registration of ids under this prefix is rejected.

const ReservedSubTypePrefix = "org.oblikovati."

func CanonicalKey​

func CanonicalKey(key string) string

CanonicalKey normalizes a raw key token so case never splits a binding: a single letter is upper-cased ("e" and "E" are the same chord), and a multi-character token ("Escape", "F5") is kept verbatim.

func SheetDimensionsMM​

func SheetDimensionsMM(s SheetSize) (width, height float64, ok bool)

SheetDimensionsMM returns a standard size's portrait width and height in millimetres (width ≤ height), and true. For SheetSizeCustom it returns (0, 0, false): a custom sheet's dimensions come from the sheet itself. Apply SheetOrientation to swap width and height for landscape.

w, h, _ := types.SheetDimensionsMM(types.SheetSizeA4) // 210, 297

type ASideFaceStatus​

ASideFaceStatus reports how a face of a mold parting was assigned to the A-side of the tooling split (parity: ASideFaceStatusEnum). The A-side faces are those that go with the cavity half; "default" means the assignment was made automatically, while "sick" flags a face whose assignment could not be resolved. The numeric values are frozen at the reference API's ids and must never be renumbered.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (ADR-0018) and maps it onto the core/cavity split result.

type ASideFaceStatus int32

const (
    // ASideDefault — the face's side was assigned automatically.
    ASideDefault ASideFaceStatus = 106241
    // ASideSick — the face is on the A-side list but its assignment is invalid.
    ASideSick ASideFaceStatus = 106242
    // ASideUpToDate — the face's side assignment is explicit and current.
    ASideUpToDate ASideFaceStatus = 106243
)

func ParseASideFaceStatus​

func ParseASideFaceStatus(s string) (ASideFaceStatus, bool)

ParseASideFaceStatus resolves a wire spelling back to its status.

func (ASideFaceStatus) String​

func (s ASideFaceStatus) String() string

String returns the status's wire spelling.

type Accuracy​

Accuracy selects the computational accuracy of a property calculation (region properties, mass properties). Higher accuracy maps to denser sampling/quadrature and costs proportionally more (M06-F08, Oblikovati/Oblikovati#623; shared vocabulary with M18-F01 mass properties).

The values are a frozen block matching the reference API's accuracy enum; never renumber them.

type Accuracy int32

const (
    AccuracyLow      Accuracy = 69377
    AccuracyMedium   Accuracy = 69378
    AccuracyHigh     Accuracy = 69379
    AccuracyVeryHigh Accuracy = 69380
)

func ParseAccuracy​

func ParseAccuracy(s string) (Accuracy, bool)

ParseAccuracy resolves a wire spelling back to its accuracy.

func (Accuracy) String​

func (a Accuracy) String() string

String returns the accuracy's wire spelling.

type ActionID​

ActionID identifies a bindable action in the keymap (M05-F17, Oblikovati#831): a registered command's id verbatim (e.g. "Feature.Extrude"), or a reserved built-in action id (e.g. "edit.undo"). It is a string so existing command-id call sites are unaffected; the host's binding engine resolves it to a command or a built-in.

type ActionID = string

type AddInKind​

AddInKind classifies an installed add-in — the ApplicationAddInTypeEnum equivalent. The host treats kinds identically today; the classification exists so UI (an add-in manager dialog) and tooling can group entries, and so translator add-ins can be routed to the exchange layer when that seam opens (M05-F01, #245).

type AddInKind uint8

const (
    // StandardAddIn is a general-purpose extension (the zero value — every add-in
    // without a declared kind).
    StandardAddIn AddInKind = 0
    // TranslatorAddIn contributes import/export format support (a
    // [oblikovati.org/api/contract.MeshTranslator] behind the wire boundary).
    TranslatorAddIn AddInKind = 1
)

func (AddInKind) String​

func (k AddInKind) String() string

String returns the kind's stable name ("standard", "translator").

type AddInLoadBehavior​

AddInLoadBehavior is when (and whether) the host activates an installed add-in — the AddInLoadBehaviorEnum equivalent, narrowed to the behaviors the host honors today. Per-document-type loading (load-with-parts/assemblies/…) is intentionally not modeled until the host has per-document applets to defer to (M05-F01, #245).

The zero value is LoadOnStartup so a freshly discovered add-in activates without any stored preference.

type AddInLoadBehavior uint8

const (
    // LoadOnStartup activates the add-in when the host starts (the default).
    LoadOnStartup AddInLoadBehavior = 0
    // LoadOnDemand registers the add-in but defers activation until something —
    // the user, another add-in, or a script — asks for it (addins.activate).
    LoadOnDemand AddInLoadBehavior = 1
    // LoadDisabled registers the add-in so it is listed, but the host never
    // activates it automatically and addins.activate refuses to.
    LoadDisabled AddInLoadBehavior = 2
)

func ParseAddInLoadBehavior​

func ParseAddInLoadBehavior(name string) (AddInLoadBehavior, bool)

ParseAddInLoadBehavior maps a stable name back to its behavior; ok is false for an unknown name (callers keep their current value rather than guessing).

b, ok := types.ParseAddInLoadBehavior("demand") // LoadOnDemand, true

func (AddInLoadBehavior) String​

func (b AddInLoadBehavior) String() string

String returns the behavior's stable name ("startup", "demand", "disabled").

type AlignmentType​

AlignmentType names how a flat-pattern orientation aligns its reference axis to the page: the chosen edge/axis is laid horizontal or vertical, then rotated by the orientation's alignment angle.

type AlignmentType int32

const (
    // HorizontalAlignment lays the orientation's alignment axis along the horizontal (the
    // default), so the flat's reported length runs left-to-right.
    HorizontalAlignment AlignmentType = iota
    // VerticalAlignment lays the alignment axis along the vertical.
    VerticalAlignment
)

func ParseAlignmentType​

func ParseAlignmentType(s string) (AlignmentType, bool)

ParseAlignmentType resolves a wire spelling back to its alignment type.

func (AlignmentType) String​

func (a AlignmentType) String() string

String returns the alignment type's wire spelling.

type AngleConstraintSolutionType​

AngleConstraintSolutionType discriminates how an angle constraint measures its angle: undirected (the unsigned angle), directed about an explicit reference axis (so the sign and full 0–360° range are meaningful), or the reference-vector form that names the third axis directly.

type AngleConstraintSolutionType uint32

const (
    // AngleSolutionUndirected is the default: the unsigned angle between the directions.
    AngleSolutionUndirected AngleConstraintSolutionType = 0
    // AngleSolutionDirected measures the signed angle about an implied reference axis.
    AngleSolutionDirected AngleConstraintSolutionType = 1
    // AngleSolutionReferenceVector measures the angle about an explicit reference vector.
    AngleSolutionReferenceVector AngleConstraintSolutionType = 2
)

func (AngleConstraintSolutionType) String​

func (s AngleConstraintSolutionType) String() string

String returns a stable lowercase name.

type AnisotropicElastic​

AnisotropicElastic holds the direction-dependent elastic constants of an orthotropic material (a transversely-isotropic material is the constrained special case E2=E3, G12=G13, ν12=ν13), expressed in the material's principal axes. Axis convention: for wood 1 = longitudinal (along grain), 2 = radial, 3 = tangential; for a unidirectional fibre lamina 1 = fibre, 2 = 3 = transverse. A solver uses these in place of the scalar Mechanical E/ν when IsotropyClass is not isotropic; yield and ultimate strengths still come from Mechanical as an equivalent scalar until directional strength allowables are added (ADR-0025).

The nine constants are the independent entries of the orthotropic compliance matrix; νIJ is the Poisson contraction along J from a load along I, with the symmetry νIJ/Ei = νJI/Ej. Alpha1..3 are the linear thermal expansion coefficients along each axis, for orthotropic thermal-stress analysis (these can be negative, e.g. the fibre direction of carbon/aramid laminates).

type AnisotropicElastic struct {
    E1  float64 `json:"e1" yaml:"e1"` // GPa, axis-1 Young's modulus
    E2  float64 `json:"e2" yaml:"e2"` // GPa, axis-2 Young's modulus
    E3  float64 `json:"e3" yaml:"e3"` // GPa, axis-3 Young's modulus

    G12 float64 `json:"g12" yaml:"g12"` // GPa, shear modulus in the 1-2 plane
    G23 float64 `json:"g23" yaml:"g23"` // GPa, shear modulus in the 2-3 plane
    G13 float64 `json:"g13" yaml:"g13"` // GPa, shear modulus in the 1-3 plane

    Nu12 float64 `json:"nu12" yaml:"nu12"` // major Poisson's ratio, load on 1 → strain on 2
    Nu23 float64 `json:"nu23" yaml:"nu23"` // major Poisson's ratio, load on 2 → strain on 3
    Nu13 float64 `json:"nu13" yaml:"nu13"` // major Poisson's ratio, load on 1 → strain on 3

    Alpha1 float64 `json:"alpha1" yaml:"alpha1"` // 1/K, axis-1 linear thermal expansion
    Alpha2 float64 `json:"alpha2" yaml:"alpha2"` // 1/K, axis-2 linear thermal expansion
    Alpha3 float64 `json:"alpha3" yaml:"alpha3"` // 1/K, axis-3 linear thermal expansion
}

type AssemblyConstraintType​

AssemblyConstraintType discriminates the assembly relationship kinds. The classic set (mate…symmetry) positions geometry; the motion set (rotate-rotate… translate-translate) couples driven values; transitional models sliding contact; custom is solved by an add-in.

type AssemblyConstraintType uint32

const (
    // ConstraintUnknown is the zero value: an unresolved or not-yet-typed constraint.
    ConstraintUnknown AssemblyConstraintType = 0
    // ConstraintMate makes two faces/edges/points coincident (normals opposed by default).
    ConstraintMate AssemblyConstraintType = 1
    // ConstraintFlush aligns two faces so their normals point the same way (co-planar).
    ConstraintFlush AssemblyConstraintType = 2
    // ConstraintAngle holds a fixed angle between two directions.
    ConstraintAngle AssemblyConstraintType = 3
    // ConstraintTangent keeps a face tangent to a curved face (inside or outside).
    ConstraintTangent AssemblyConstraintType = 4
    // ConstraintInsert combines an axis mate with a plane mate (a bolt into a hole).
    ConstraintInsert AssemblyConstraintType = 5
    // ConstraintSymmetry positions two occurrences symmetrically about a plane.
    ConstraintSymmetry AssemblyConstraintType = 6
    // ConstraintRotateRotate couples two rotations by a gear ratio.
    ConstraintRotateRotate AssemblyConstraintType = 7
    // ConstraintRotateTranslate couples a rotation to a translation (rack and pinion).
    ConstraintRotateTranslate AssemblyConstraintType = 8
    // ConstraintTranslateTranslate couples two translations by a ratio.
    ConstraintTranslateTranslate AssemblyConstraintType = 9
    // ConstraintTransitional keeps a face in sliding contact with a set of faces.
    ConstraintTransitional AssemblyConstraintType = 10
    // ConstraintCustom is a relationship solved by an add-in, not the built-in solver.
    ConstraintCustom AssemblyConstraintType = 11
)

func (AssemblyConstraintType) IsValid​

func (t AssemblyConstraintType) IsValid() bool

IsValid reports whether t names a real constraint kind (not unknown).

func (AssemblyConstraintType) String​

func (t AssemblyConstraintType) String() string

String returns a stable lowercase name, used in diagnostics and the wire DTOs. The value, not this name, is the persisted identity.

type AssemblyJointOriginDefinitionType​

AssemblyJointOriginDefinitionType discriminates how a joint origin (the frame the joint is built on, on each component) is defined: from a point, an edge/axis, or a planar face.

type AssemblyJointOriginDefinitionType uint32

const (
    // JointOriginUnknown is the zero value.
    JointOriginUnknown AssemblyJointOriginDefinitionType = 0
    // JointOriginPoint derives the origin frame from a vertex / work point.
    JointOriginPoint AssemblyJointOriginDefinitionType = 1
    // JointOriginEdge derives the origin frame from an edge / axis (its line).
    JointOriginEdge AssemblyJointOriginDefinitionType = 2
    // JointOriginPlane derives the origin frame from a planar face / work plane (its normal).
    JointOriginPlane AssemblyJointOriginDefinitionType = 3
)

func (AssemblyJointOriginDefinitionType) String​

func (t AssemblyJointOriginDefinitionType) String() string

String returns a stable lowercase name.

type AssemblyJointType​

AssemblyJointType discriminates the standard joint kinds, ordered by remaining freedom: rigid (0 DOF) through ball (3 rotational DOF). A joint reduces the relative placement of two occurrences to exactly its degrees of freedom.

type AssemblyJointType uint32

const (
    // JointUnknown is the zero value: an unresolved or not-yet-typed joint.
    JointUnknown AssemblyJointType = 0
    // JointRigid fully fixes the two occurrences together (0 DOF).
    JointRigid AssemblyJointType = 1
    // JointRotational allows one rotation about the joint axis (1 DOF).
    JointRotational AssemblyJointType = 2
    // JointSlider allows one translation along the joint axis (1 DOF).
    JointSlider AssemblyJointType = 3
    // JointCylindrical allows translation along and rotation about the axis (2 DOF).
    JointCylindrical AssemblyJointType = 4
    // JointPlanar allows two translations in a plane and one rotation about its normal (3 DOF).
    JointPlanar AssemblyJointType = 5
    // JointBall allows three rotations about a common point (3 DOF).
    JointBall AssemblyJointType = 6
)

func (AssemblyJointType) DegreesOfFreedom​

func (t AssemblyJointType) DegreesOfFreedom() int

DegreesOfFreedom returns the number of free DOF a joint of this kind leaves between the two occurrences (rigid 0 … ball 3) — the value the solver's rank analysis must produce.

func (AssemblyJointType) IsValid​

func (t AssemblyJointType) IsValid() bool

IsValid reports whether t names a real joint kind (not unknown).

func (AssemblyJointType) String​

func (t AssemblyJointType) String() string

String returns a stable lowercase name. The value, not this name, is the persisted identity.

type AssetSource​

AssetSource says where an appearance or material asset comes from, which fixes its edit policy and resolution priority. A document-embedded copy is authoritative for portability, then the project library (the shared catalog), then the shipped built-ins (read-only). This follows the standard library/document asset distinction.

This is the canonical, Apache-2.0 definition; the GPL model aliases it (model/material.Source = types.AssetSource).

type AssetSource string

const (
    // AssetBuiltin is a shipped, read-only catalog asset.
    AssetBuiltin AssetSource = "builtin"
    // AssetProject is a user asset in the active project's shared library.
    AssetProject AssetSource = "project"
    // AssetDocument is a copy embedded in a document (so the .obk is self-contained).
    AssetDocument AssetSource = "document"
)

func (s AssetSource) Editable() bool

Editable reports whether the user may modify an asset of this source (everything but the read-only built-ins).

type AttachmentKind​

AttachmentKind classifies a document's reference to a foreign (non-native) file: linked in place, embedded as a payload carried inside the document, or a generic tracked path (M03-F08, Oblikovati/Oblikovati#609).

The values are a frozen block matching the reference API's foreign-document type enum; never renumber them.

type AttachmentKind int32

const (
    // AttachmentGeneric is an opaque tracked path: the document records the
    // file but assigns it no further semantics.
    AttachmentGeneric AttachmentKind = 3329
    // AttachmentEmbedded carries the foreign file's bytes inside the document
    // (as an embedded resource), so it travels with the .obk.
    AttachmentEmbedded AttachmentKind = 3330
    // AttachmentLinked references the foreign file in place; the document
    // tracks its path and last-known modification time.
    AttachmentLinked AttachmentKind = 3331
)

func ParseAttachmentKind(s string) (AttachmentKind, bool)

ParseAttachmentKind resolves a wire spelling back to its AttachmentKind.

type BOMStructure string

const (
    // BOMNormal is a counted row whose sub-assembly children are expanded.
    BOMNormal BOMStructure = "normal"
    // BOMPhantom is not a row of its own: its children are promoted into its parent.
    BOMPhantom BOMStructure = "phantom"
    // BOMReference is shown for context but never counted.
    BOMReference BOMStructure = "reference"
    // BOMPurchased is a bought item counted as one line; its children are not broken out.
    BOMPurchased BOMStructure = "purchased"
    // BOMInseparable is a welded/glued sub-assembly counted as one line; not broken out.
    BOMInseparable BOMStructure = "inseparable"
)

type BOMViewKind​

BOMViewKind selects a bill-of-materials view.

type BOMViewKind string

const (
    // BOMStructured is the hierarchical view: top-level rows with sub-assembly children
    // nested, quantities counted per parent.
    BOMStructured BOMViewKind = "structured"
    // BOMPartsOnly is the flat view: every unique counted part once, with its total
    // quantity across the whole assembly.
    BOMPartsOnly BOMViewKind = "partsOnly"
)

type BSplineCurve2dDef​

BSplineCurve2dDef is the 2D NURBS curve recipe.

type BSplineCurve2dDef struct {
    Degree  int       `json:"degree"`
    Poles   []Point2d `json:"poles"`
    Weights []float64 `json:"weights,omitempty"`
    Knots   []float64 `json:"knots"`
}

type BSplineCurveDef​

    Degree  int       `json:"degree"`
    Poles   []Point   `json:"poles"`
    Weights []float64 `json:"weights,omitempty"`
    Knots   []float64 `json:"knots"`
}

type BSplineSurfaceDef​

    KnotsU  []float64 `json:"knotsU"`
    KnotsV  []float64 `json:"knotsV"`
}

type BackFaceCullingEnum​

BackFaceCullingEnum is which triangle winding the renderer culls: none, clockwise, or counter-clockwise. Frozen ids 96769–96771.

type BackFaceCullingEnum int32

const (
    // CullNone draws both faces of every triangle (96769).
    CullNone BackFaceCullingEnum = 96769
    // CullClockwise culls clockwise-wound faces (96770).
    CullClockwise BackFaceCullingEnum = 96770
    // CullCounterClockwise culls counter-clockwise-wound faces (96771).
    CullCounterClockwise BackFaceCullingEnum = 96771

First consumed by the color-scheme palette (which carries the background colors); the display-settings surface reuses it. This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.BackgroundTypeEnum).

type BackgroundTypeEnum int32

const (
    // OneColorBackground paints a single solid background color (52737).
    OneColorBackground BackgroundTypeEnum = 52737
    // GradientBackground paints a top-to-bottom two-color gradient (52738).
    GradientBackground BackgroundTypeEnum = 52738
    // ImageBackground paints a background image (52739).
    ImageBackground BackgroundTypeEnum = 52739
)

type BendPartType​

BendPartType discriminates how a Bend Part feature's geometry is driven (parity: BendPartTypeEnum). A bend wraps a solid body around a sketch bend line; exactly two of {radius, angle, arc length} are supplied and the third is derived, so the type names which pair the definition carries. The numeric values are frozen at the reference API's ids and must never be renumbered.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (ADR-0018) and maps it onto the bend kernel op.

type BendPartType int32

const (
    // ArcLengthAndAngleBend drives the bend by its arc length and bend angle (radius derived).
    ArcLengthAndAngleBend BendPartType = 83457
    // RadiusAndAngleBend drives the bend by its bend radius and angle (arc length derived).
    RadiusAndAngleBend BendPartType = 83458

type Box​

Box is an axis-aligned 3D bounding range. An empty box has Min > Max in some component (the zero value, with both at the origin, is the degenerate single-point box; use NewEmptyBox for the absorbing identity of Union).

type Box struct {

    Max Point `json:"max"`
}

}

type ButtonStyle​

ButtonStyle is how a command renders in the ribbon, narrowed to the four styles we support. The control's behavior is identical; only its size and how the icon and display name combine differ.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (app.ButtonStyle) so existing call sites are unaffected.

type ButtonStyle uint8

const (
    // TextOnlyButton shows the display name as a plain button (the zero value).
    TextOnlyButton ButtonStyle = 0
    // SmallIconButton shows a small (16px) icon with the display name beside it —
    // the stacked rows of a ribbon panel (Move / Copy / Rotate).

    // LargeIconButton shows a large (32px) icon with the name as a caption beneath.
    LargeIconButton ButtonStyle = 2
    // CompactIconButton shows a small (16px) icon only, no label — dense tool grids

    CompactIconButton ButtonStyle = 3
)

type ChamferConcaveStrategy​

ChamferConcaveStrategy selects how an edge chamfer treats a CONCAVE (internal) edge — one where the two faces fold over the material so the dihedral exceeds π (e.g. the inside corner where a rib meets a plate). A convex edge always cuts its corner and ignores this. An Oblikovati extension with no reference-API equivalent, so the numeric block below is OURS (chosen clear of the frozen reference blocks) — but, once shipped, equally frozen: never renumber.

  • ChamferConcaveOutward — fill the inside corner with material: a flat 45° gusset that bridges the two faces (Boolean union). The DEFAULT; the zero value resolves to it.
  • ChamferConcaveInward — instead cut a recessed groove into the corner, relieving it (Boolean cut on the material side).
type ChamferConcaveStrategy int32

const (
    // ChamferConcaveOutward fills the inside corner with material (the default, also the zero value).
    ChamferConcaveOutward ChamferConcaveStrategy = 200101

type ChamferType int32

const (
    // ChamferDistance — equal setback distance along both adjacent faces.
    ChamferDistance ChamferType = 26881
    // ChamferDistanceAndAngle — a distance on the first face and the chamfer-face angle.
    ChamferDistanceAndAngle ChamferType = 26882
    // ChamferTwoDistances — independent setback distances on each adjacent face (asymmetric).
    ChamferTwoDistances ChamferType = 26883

type Color​

Color is the universal color value object: the currency of the whole visual surface (render styles, lights, highlight sets, client-graphics color sets, display settings all traffic in it). It is plain data — 8-bit R/G/B components, a 0–1 Opacity (0 fully transparent, 1 fully opaque), and a Source discriminating an override from an inherited color. It mirrors the reference Color object's Red/Green/Blue/Opacity/ColorSourceType.

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.Color = types.Color) so the head, renderer, and model share one color type.

c := types.NewColor(255, 0, 0)            // opaque red, override source
c.Opacity = 0.5                           // half-transparent

}

func NewColor​

func NewColor(r, g, b uint8) Color

NewColor builds an opaque override Color from 8-bit R/G/B components — the common case.

func (Color) Hex​

func (c Color) Hex() string

Hex formats the color as "#RRGGBB" (lower-case), ignoring opacity — the form a scheme file stores for an opaque swatch.

func (Color) Rgba​

func (c Color) Rgba() Rgba

Rgba converts to the renderer's Rgba (float32 channels in [0,1], Opacity → alpha), so a Color crosses to the draw path without a bespoke conversion at every call site.

type ColorBindingEnum​

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.ColorSourceTypeEnum).

type ColorSourceTypeEnum int32

const (
    // OverrideColorSource: the color is an explicit per-object override (79105).
    OverrideColorSource ColorSourceTypeEnum = 79105
    // AutomaticColorSource: the color is the automatic (by-class) color (79106).
    AutomaticColorSource ColorSourceTypeEnum = 79106
    // LayerColorSource: the color is inherited from the object's layer (79107).
    LayerColorSource ColorSourceTypeEnum = 79107
    // SheetColorSource: the color is inherited from the object's sheet (79108).

type ControlKind​

ControlKind is how a command behaves as a ribbon control — the CommandControl-type discriminator. The kind decides interaction (one-shot, on/off, pick-one, numeric, menu), while ButtonStyle decides only its look.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (app.ControlKind) so existing call sites are unaffected.

type ControlKind uint8

type DXFVersion​

DXFVersion selects the generation an exported DXF targets. The geometry is identical across versions; the version sets $ACADVER and the surrounding section scaffolding. The zero value "" is treated as R2000.

Example:

req := wire.ExportDXFArgs{Path: "part.dxf", Version: string(types.DXFR2018)}
type DXFVersion string

const (
    // DXFR2000 is the AutoCAD 2000 (AC1015) generation — broadest compatibility.

The numeric ids are stable, frozen values (8706–8716); two names share 8707 (the aliases HiddenEdgeRendering and ShadedWithHiddenEdgesRendering). This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.DisplayModeEnum) and maps it onto the renderer's visual style.

type DisplayModeEnum int32

const (
    // WireframeRendering — every edge, no shaded faces, no hidden-line removal (8706).
    WireframeRendering DisplayModeEnum = 8706

The numeric ids are stable, frozen values (26113–26116).

Used by the display-options surface and by client-graphics image/text primitives. This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.DisplayTransformBehaviorEnum).

type DisplayTransformBehaviorEnum int32

const (
    // FrontFacingBehavior keeps the graphic facing the viewer (billboarding) (26113).
    FrontFacingBehavior DisplayTransformBehaviorEnum = 26113
    // PixelScalingBehavior keeps a constant pixel size regardless of zoom (26114).
    PixelScalingBehavior DisplayTransformBehaviorEnum = 26114

DockingState is where a dockable window sits — the DockingStateEnum equivalent, narrowed to the positions the host's dockspace honors (M05-F03, #247). It is the window's INITIAL placement; the user may re-dock it afterwards and the host's layout persistence keeps their arrangement.

type DockingState uint8

    // DockFloating is a free-floating window (the zero value).
    DockFloating DockingState = 0
    // DockLeft docks into the left band (beside the model browser).

func (d DockingState) String() string

String returns the state's stable name.

type DocumentInterestRecord​

DocumentInterestRecord is one entry of a document's add-in data registry: client X has data in / depends on this document. Unlike attribute sets (arbitrary payload on arbitrary objects), an interest is a lightweight discovery contract readable without activating the owning add-in.

type DocumentInterestRecord struct {
    // ClientID uniquely identifies the owning client (an add-in id).
    ClientID string `json:"clientId"`
    // Name names this interest, typically the data's sub-type; (ClientID,

    Name string `json:"name"`
    // InterestType is the interest's strength.
    InterestType DocumentInterestType `json:"interestType"`
    // DataVersion is the client-managed migration version; 0 declares a
    // non-migrating interest.
    DataVersion int `json:"dataVersion,omitempty"`
    // ClientData is an uninterpreted client payload — use with extreme
    // economy (attribute sets are the payload layer).

type DocumentSubTypeID​

DocumentSubTypeID refines a document's base DocumentType with a flavored sub-type: a sheet-metal part is a part document carrying the sheet-metal sub-type id (M03-F11, Oblikovati/Oblikovati#612). The empty id is a plain document. Add-ins register their own ids over documents.registerSubType (M05-F15); ids under ReservedSubTypePrefix are built-in and cannot be registered by clients.

type DocumentSubTypeID string

const (
    // SubTypePlain is the absent sub-type: an unflavored document.
    SubTypePlain DocumentSubTypeID = ""
    // SubTypeSheetMetalPart flavors a part document as sheet metal — reserved
    // now so .obk files persist the discriminator from the first release; the
    // sheet-metal environment itself lands with M20.
    SubTypeSheetMetalPart DocumentSubTypeID = "org.oblikovati.part.sheetMetal"
)

func (DocumentSubTypeID) BuiltIn​

func (id DocumentSubTypeID) BuiltIn() bool

BuiltIn reports whether the id is reserved by the host (or plain).

DocumentType discriminates the four document kinds plus an unknown sentinel.

Values are STABLE ACROSS SESSIONS and must never be renumbered: they are persisted in package manifests and the document reference graph (architecture core/05). This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (model/doc.DocumentType) so existing call sites are unaffected.

type DocumentType uint32

const (
    // DocumentUnknown is the zero value: a document whose kind has not been
    // resolved (e.g. an unresolved reference stub before its manifest is read).
    DocumentUnknown DocumentType = 0
    // DocumentPart holds a single modeled part.
    DocumentPart DocumentType = 1
    // DocumentAssembly holds component occurrences and constraints.
    DocumentAssembly DocumentType = 2

    // DrawingViewBase projects a standard orientation of the model.
    DrawingViewBase DrawingViewType = iota
    // DrawingViewProjected is an orthographic view derived from a base view by a direction.
    DrawingViewProjected

func ParseDrawingViewType​

func ParseDrawingViewType(s string) (DrawingViewType, bool)

ParseDrawingViewType resolves a wire spelling back to its view type.

func (DrawingViewType) String​

func (t DrawingViewType) String() string

String returns the view type's wire spelling ("base", "auxiliary").

type DriveVariable​

DriveVariable selects which of a relationship's driven variables a drive sweeps. A rotational joint has one angular variable; a slider one linear; a cylindrical joint both, so the caller must pick. The zero value asks for the relationship's natural variable.

type DriveVariable uint32

const (
    // DriveNatural sweeps the relationship's single natural driven variable (the rotation of
    // a rotational joint, the translation of a slider). Ambiguous for multi-DOF kinds.
    DriveNatural DriveVariable = 0
    // DriveAngular sweeps a rotation about the joint axis (radians).
    DriveAngular DriveVariable = 1
    // DriveLinear sweeps a translation along the joint axis (centimetres).
    DriveLinear DriveVariable = 2
)

func (DriveVariable) IsValid​

func (v DriveVariable) IsValid() bool

IsValid reports whether v names a real selector value.

func (DriveVariable) String​

func (v DriveVariable) String() string

String returns a stable lowercase name. The value, not this name, is the persisted identity.

type EdgeCollectionKind​

EdgeCollectionKind identifies a body's classified edge collection (SurfaceBody.ConvexEdges / ConcaveEdges and tangentially connected sets).

type EdgeCollectionKind int32

const (
    TangentiallyConnectedEdges EdgeCollectionKind = 27649
    AllConcaveEdges            EdgeCollectionKind = 27650
    AllConvexEdges             EdgeCollectionKind = 27651

ParseEdgeCollectionKind resolves a wire spelling back to its collection.

func (EdgeCollectionKind) String​

func (k EdgeCollectionKind) String() string

String returns the collection's wire spelling.

type Electrical​

Electrical groups a material's electrical properties. Common mechanical-CAD material models stop at mechanical/thermal; electrical is added here because the user models it explicitly.

type Electrical struct {
    Resistivity          float64 `json:"resistivity" yaml:"resistivity"`                   // Ω·m
    RelativePermittivity float64 `json:"relativePermittivity" yaml:"relativePermittivity"` // dimensionless (εr)
}

type Environment​

Environment is a ribbon context within a document. The base environment is always shown; a contextual environment (e.g. sketch editing) contributes its tabs only while it is active — the mechanism behind a contextual tab such as the Sketch tab. An add-in scopes a control to an environment so it appears only in that context.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (app.Environment) so existing call sites are unaffected.

type Environment uint8

const (
    // BaseEnvironment is the document's normal environment; its controls always show.
    BaseEnvironment Environment = 0
    // SketchEnvironment is active while a 2D sketch is open for editing; its controls form the
    // contextual Sketch tab and show only then.
    SketchEnvironment Environment = 1
    // Sketch3DEnvironment is active while a 3D sketch is open for editing; its controls form the
    // contextual 3D Sketch tab and show only then. Distinct from SketchEnvironment so the 2D and
    // 3D sketch tabs never appear together.
    Sketch3DEnvironment Environment = 2
)

func (Environment) String​

func (e Environment) String() string

String returns the environment's stable name.

type ExchangeFormat​

ExchangeFormat names a foreign file format the host can import from or export to. It is a pure value enum (a stable wire string); the parser/encoder lives in the GPL host, never here. STEP is reserved (its translator ships separately, M17-F02).

Example:

req := wire.ExportRequest{Path: "part.stl", Format: string(types.FormatSTL)}
type ExchangeFormat string

const (
    // FormatSTL is the STL triangle-soup format (binary on export; binary or ASCII on import).
    FormatSTL ExchangeFormat = "stl"
    // FormatOBJ is the Wavefront OBJ format (v/f records).
    FormatOBJ ExchangeFormat = "obj"
    // Format3MF is the 3D Manufacturing Format (a ZIP container around a 3D-model XML part).
    Format3MF ExchangeFormat = "3mf"
    // FormatPLY is the Stanford PLY format (ASCII or binary), the common export of 3D scanners
    // (structured-light / photogrammetry). It carries a vertex list (and, for a mesh, faces); the
    // host imports it as a POINT CLOUD — as-built reference scan data — not as a solid/mesh body,
    // so it is a point-cloud format (IsPointCloud), not a mesh format (#645).
    FormatPLY ExchangeFormat = "ply"
    // FormatE57 is the ASTM E2807 (E57) format, the vendor-neutral, structured export of most
    // laser/structured-light scanners (its points live in a bit-packed CompressedVector inside a
    // checksummed-page container). Like PLY the host imports it as a POINT CLOUD — as-built scan
    // data — so it is a point-cloud format (IsPointCloud), not a mesh format (#645).
    FormatE57 ExchangeFormat = "e57"
    // FormatLAS is the ASPRS LAS format, the standard interchange for LiDAR point data (airborne
    // and terrestrial surveys); each fixed-length record carries a scaled-integer XYZ. The host
    // imports it as a POINT CLOUD — scan data — so it is a point-cloud format (IsPointCloud), not a
    // mesh format. The compressed LAZ variant is not handled (#645).
    FormatLAS ExchangeFormat = "las"
    // FormatSTEP reserves the ISO 10303 B-rep format (translator ships separately, M17-F02).
    FormatSTEP ExchangeFormat = "step"
    // FormatDWG is the AutoCAD DWG drawing format. Unlike the mesh/B-rep formats it
    // carries 2D/3D curve geometry, so it imports into a sketch (2D Sketch on a chosen
    // plane, or Sketch3D) rather than into surface bodies.
    FormatDWG ExchangeFormat = "dwg"
    // FormatDXF is the ASCII DXF drawing-exchange format — DWG's open, text sibling. Like
    // DWG it carries curve geometry and imports into a sketch; on export the version is
    // selectable (see DXFVersion).
    FormatDXF ExchangeFormat = "dxf"
    // FormatPDF is a vector PDF whose page content was generated from a CAD drawing
    // (e.g. an AutoCAD plot-to-PDF). Like DWG/DXF it carries 2D curve geometry — page
    // paths (lines and cubic Béziers) — so it imports into a sketch (one 2D Sketch per
    // page on the chosen plane) rather than into surface bodies. Text and raster images
    // in the page are skipped; only vector paths become sketch curves.
    FormatPDF ExchangeFormat = "pdf"
)

func (ExchangeFormat) IsMesh​

func (f ExchangeFormat) IsMesh() bool

IsMesh reports whether the format is a faceted-mesh format (STL/OBJ/3MF) — the set the mesh-exchange translator handles. STEP is a B-rep format (a different translator).

func (ExchangeFormat) IsPointCloud​

func (f ExchangeFormat) IsPointCloud() bool

IsPointCloud reports whether the format imports as point-cloud scan data (a referenced display object the design is modeled against) rather than as a body or sketch — the 3D-scanner / LiDAR formats (PLY, E57, LAS). Such an import attaches a point cloud, not a solid (#645).

func (ExchangeFormat) IsSketch​

func (f ExchangeFormat) IsSketch() bool

IsSketch reports whether the format imports as sketch curve geometry (DWG/DXF/PDF) rather than as surface bodies (mesh/STEP). Such an import targets a sketch and, when 2D, a chosen work plane.

type FeatureApproximationType​

FeatureApproximationType is the approximation a thicken / face-offset feature may accept when the exact offset is not computable (#331 parity). An exact result satisfies every bound below, so a kernel computing the exact offset honours any requested approximation.

type FeatureApproximationType int32

const (
    NoApproximation            FeatureApproximationType = 60673
    MeanApproximation          FeatureApproximationType = 60674

type FileLocationType​

FileLocationType classifies where a referenced file lives relative to the design project's search roots — the editable workspace, a shared workgroup, a read-only library, or somewhere unmanaged (M03-F07, Oblikovati/Oblikovati#608).

The values are a frozen block matching the reference API's location-type enum; never renumber them.

type FileLocationType int32

const (
    // LocationWorkspace is the project's primary editable root.
    LocationWorkspace FileLocationType = 45057
    // LocationLocal is an auxiliary local workspace root.
    LocationLocal FileLocationType = 45058
    // LocationWorkgroup is a shared root of files being concurrently worked on.
    LocationWorkgroup FileLocationType = 45059
    // LocationLibrary is a shared, typically read-only catalog root.
    LocationLibrary FileLocationType = 45060
    // LocationUnknown is a path outside every configured root.
    LocationUnknown FileLocationType = 45061
    // LocationOwnerDirectory is the directory of the file holding the reference
    // (sibling-relative resolution).
    LocationOwnerDirectory FileLocationType = 45062
    // LocationCloud is a connected/synchronized network location.
    LocationCloud FileLocationType = 45063
)

ParseFileLocationType resolves a wire spelling back to its FileLocationType.

func (FileLocationType) String​

func (l FileLocationType) String() string

String returns the location type's wire spelling.

type FilletConcaveStrategy​

FilletConcaveStrategy selects how a fillet treats a CONCAVE (internal) edge — one where the two faces fold over the material (dihedral > π), e.g. the inside corner where a rib meets a plate. A convex edge always rounds its corner away and ignores this. The fillet keeps an exact rolling-ball cylinder face either way; only which side the ball rolls on (and thus whether material is added or removed) changes. An Oblikovati extension (no reference-API equivalent); the block is OURS but, once shipped, equally frozen: never renumber.

  • FilletConcaveOutward — fill the inside corner with material (a concave fillet bridging the two faces). The DEFAULT; the zero value resolves to it.
  • FilletConcaveInward — round a recess into the corner instead (material removed).
type FilletConcaveStrategy int32

const (
    // FilletConcaveOutward fills the inside corner with material (the default, also the zero value).
    FilletConcaveOutward FilletConcaveStrategy = 200111
    // FilletConcaveInward rounds a recess into the inside corner instead (material removed).
    FilletConcaveInward FilletConcaveStrategy = 200112
)

ParseFilletConcaveStrategy resolves a wire spelling back to its strategy.

func (FilletConcaveStrategy) String​

func (t FilletConcaveStrategy) String() string

String returns the concave strategy's wire spelling.

type FilletCornerType​

FilletCornerType selects how an edge fillet treats a corner where two filleted edges meet at a vertex whose third edge stays sharp (the two rolling-ball cylinders cannot be joined by a single sphere unless that third edge is also rounded). It is an Oblikovati extension with no reference-API equivalent, so the numeric block below is OURS (chosen clear of the frozen reference blocks above) — but, once shipped, it is equally frozen: never renumber.

  • FilletCornerMiter — the two cylinders mutually trim along their intersection seam (a crease); the geometrically exact rolling-ball result for rounding only two of a corner's three edges.
  • FilletCornerSetback — a spherical corner patch tangent to the three faces, set back from the sharp edge by a small planar setback face (a smoothed corner; not the exact rolling-ball form).
  • FilletCornerRound — round the corner fully into a single sphere octant by also rolling over the third edge (the true 3-edge blend; the corner becomes G1-smooth all round).
type FilletCornerType int32

const (
    // FilletCornerMiter is the default: a crease seam where the two cylinders mutually trim.
    FilletCornerMiter FilletCornerType = 200001
    // FilletCornerSetback is a spherical patch set back from the sharp edge by a planar face.
    FilletCornerSetback FilletCornerType = 200002
    // FilletCornerRound rounds the corner fully into a sphere octant (rolls over the third edge).
    FilletCornerRound FilletCornerType = 200003
)

func (FilletCornerType) String​

func (t FilletCornerType) String() string

String returns the corner type's wire spelling.

type FilletCrossSection​

FilletCrossSection selects the shape of an edge blend's cross-section profile (M36-F08): the default circular arc (G1 — tangent to both walls), a curvature-continuous G2 profile (zero curvature at the tangency lines, so a blend between flat walls has no curvature jump), or a conic (rho-controlled) profile whose shoulder fullness is set by a separate rho parameter. It is a string enum so the empty value reads as the arc default; the kernel maps it to its blend builder.

type FilletCrossSection string

const (
    // FilletSectionArc is the circular rolling-ball cross-section (G1; the empty/default value).
    FilletSectionArc FilletCrossSection = "arc"
    // FilletSectionG2 is a curvature-continuous cross-section (no curvature jump at the tangency lines).
    FilletSectionG2 FilletCrossSection = "g2"
    // FilletSectionConic is a conic (rho-controlled) cross-section; pair it with a rho fullness value.

type FlatPatternEdgeType​

FlatPatternEdgeType classifies an edge of the developed flat for manufacturing and drawing: a fold line where the sheet bends up or down, or a tangent line where a curved wall met the flat tangentially. Outer-profile (cut) edges carry no flat-pattern type.

type FlatPatternEdgeType int32

const (
    // BendUpFlatPatternEdge is a fold line whose bend lifts the material toward the front
    // (top) face when the flat is refolded.
    BendUpFlatPatternEdge FlatPatternEdgeType = iota
    // BendDownFlatPatternEdge is a fold line whose bend lifts the material toward the back.

const (
    // UnknownFlatPatternFace is a face the flat pattern does not classify.
    UnknownFlatPatternFace FlatPatternFaceType = iota
    // FrontFlatPatternFace is the top face the active orientation presents.
    FrontFlatPatternFace
    // BackFlatPatternFace is the bottom face.
    BackFlatPatternFace
    // DetailFlatPatternFace is a face carrying punch/relief detail.

"persistent" is client graphics (document-owned, lives until deleted); "overlay" and "preview" are the interaction-graphics lanes (command-scoped, cleared when the interaction ends). Overlay graphics draw on top of the scene (depth-test off); preview graphics draw depth-tested with the scene.

GraphicsPrimitiveKind names the topology of one graphics primitive (line, point, triangle, or text graphics). It is the discriminator of a oblikovati.org/api/wire.GraphicsPrimitive.

type GraphicsPrimitiveKind string

const (
    // GraphicsLines is an indexed line list (segment pairs).
    GraphicsLines GraphicsPrimitiveKind = "lines"
    // GraphicsLineStrip is a connected polyline (each vertex joins the previous).
    GraphicsLineStrip GraphicsPrimitiveKind = "lineStrip"
    // GraphicsPoints is a set of point markers drawn with a [GraphicsPointStyle] glyph.
    GraphicsPoints GraphicsPrimitiveKind = "points"
    // GraphicsTriangles is an indexed triangle mesh (the heatmap/surface primitive).
    GraphicsTriangles GraphicsPrimitiveKind = "triangles"
    // GraphicsTriangleStrip is a triangle strip (each vertex extends the previous two).
    GraphicsTriangleStrip GraphicsPrimitiveKind = "triangleStrip"
    // GraphicsTriangleFan is a triangle fan (each vertex joins the first and the previous).
    GraphicsTriangleFan GraphicsPrimitiveKind = "triangleFan"
    // GraphicsText is a world-anchored text label.
    GraphicsText GraphicsPrimitiveKind = "text"
    // GraphicsSurface renders an existing B-rep body/face by reference key, with an optional
    // override color/transform — the SurfaceGraphics equivalent (geometry stays host-side).
    GraphicsSurface GraphicsPrimitiveKind = "surface"
    // GraphicsCurve renders an existing B-rep edge by reference key — the CurveGraphics equivalent.
    GraphicsCurve GraphicsPrimitiveKind = "curve"
    // GraphicsImage is a world- or screen-anchored image billboard (a textured quad).
    GraphicsImage GraphicsPrimitiveKind = "image"
)

type GraphicsSelectabilityEnum​

GraphicsSelectabilityEnum is whether none, some, or all of a graphics node's geometry can be picked. Frozen ids 25345–25347.

type GraphicsSelectabilityEnum int32

const (
    // NoGraphicsSelectable makes none of the node selectable (25345).
    NoGraphicsSelectable GraphicsSelectabilityEnum = 25345
    // SomeGraphicsSelectable makes part of the node selectable (25346).
    SomeGraphicsSelectable GraphicsSelectabilityEnum = 25346
    // AllGraphicsSelectable makes all of the node selectable (25347).
    AllGraphicsSelectable GraphicsSelectabilityEnum = 25347
)

func AllGraphicsSelectabilities​

func AllGraphicsSelectabilities() []GraphicsSelectabilityEnum

AllGraphicsSelectabilities returns every defined selectability.

func (GraphicsSelectabilityEnum) IsValid​

func (g GraphicsSelectabilityEnum) IsValid() bool

IsValid reports whether g is a defined selectability.

func (GraphicsSelectabilityEnum) String​

func (g GraphicsSelectabilityEnum) String() string

String returns the selectability's user-facing name.

type GraphicsVisibilityEnum int32

const (
    // NoGraphicsVisible hides the whole node (25089).
    NoGraphicsVisible GraphicsVisibilityEnum = 25089
    // SomeGraphicsVisible shows part of the node (25090).
    SomeGraphicsVisible GraphicsVisibilityEnum = 25090

func (GraphicsVisibilityEnum) String​

func (g GraphicsVisibilityEnum) String() string

String returns the visibility's user-facing name.

type GridCell​

GridCell is the explicit placement of one child inside its parent grid. Col is the 0-based column; ColSpan (>=1; 0 is treated as 1) is how many columns the child covers. A child with no Cell (nil pointer on the wire) auto-flows into the next free cell.

Row and RowSpan are reserved for a later slice: the wire shape accepts them so it stays forward-stable, but the host renders rows as content-height auto-flow, so RowSpan must be 1 in this version (the router rejects RowSpan > 1).

type GridCell struct {
    Col     int `json:"col,omitempty"`
    Row     int `json:"row,omitempty"`
    ColSpan int `json:"colSpan,omitempty"`
    RowSpan int `json:"rowSpan,omitempty"`
}

type GridTrack​

GridTrack is one column track of a grid. Value is pixels when Fixed and the fraction weight when Fraction (ignored when Auto). MinPx/MaxPx (0 = unset) clamp the resolved width, expressing CSS minmax(): e.g. a 1fr track that never shrinks below 80px is {Kind: GridTrackFraction, Value: 1, MinPx: 80}.

Example: a label/field form is two tracks — TrackAuto() for labels, TrackFr(1) for fields.

type GridTrack struct {
    Kind  GridTrackKind `json:"kind,omitempty"`
    Value float64       `json:"value,omitempty"`
    MinPx float64       `json:"minPx,omitempty"`
    MaxPx float64       `json:"maxPx,omitempty"`
}

type GridTrackKind​

GridTrackKind is how one grid column track is sized.

type GridTrackKind uint8

const (
    // GridTrackAuto sizes the track to its content (the zero value).
    GridTrackAuto GridTrackKind = 0
    // GridTrackFixed sizes the track to exactly Value pixels.
    GridTrackFixed GridTrackKind = 1
    // GridTrackFraction sizes the track to a share of the leftover space; Value is the
    // fraction weight (CSS "fr"): a 2fr track gets twice the leftover a 1fr track gets.
    GridTrackFraction GridTrackKind = 2
)

type GroundShadowEnum​

GroundShadowEnum is how the scene casts shadows onto the ground plane: none, a standard ground shadow, or an X-ray (see-through) ground shadow. The numeric ids are stable, frozen values (69121–69123).

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.GroundShadowEnum).

type GroundShadowEnum int32

const (
    // NoGroundShadow casts no ground shadow (69121).
    NoGroundShadow GroundShadowEnum = 69121
    // GroundShadow casts a standard ground shadow (69122).
    GroundShadow GroundShadowEnum = 69122
    // XRayGroundShadow casts a see-through (X-ray) ground shadow (69123).
    XRayGroundShadow GroundShadowEnum = 69123
)

func AllGroundShadows​

func AllGroundShadows() []GroundShadowEnum

AllGroundShadows returns every defined ground-shadow mode, in picker order.

IsValid reports whether g is a defined ground-shadow mode.

func (GroundShadowEnum) String​

func (g GroundShadowEnum) String() string

String returns the ground-shadow mode's user-facing name.

type HatchPattern​

HatchPattern is a built-in hatch line family. The zero value is HatchGeneral (single 45° lines).

type HatchPattern int32

const (
    // HatchGeneral is the general-purpose single hatch: parallel lines at 45°.
    HatchGeneral HatchPattern = iota
    // HatchCross is cross-hatch: two perpendicular line families at ±45°.
    HatchCross
    // HatchANSI31 is the ANSI iron/general pattern: parallel lines at 45° (a closer spacing).
    HatchANSI31
)

ParseHatchPattern resolves a wire spelling back to its pattern.

p, ok := types.ParseHatchPattern("cross") // HatchCross, true

func (HatchPattern) String​

func (p HatchPattern) String() string

String returns the pattern's wire spelling ("general", "cross", "ansi31").

type HealthStatus​

HealthStatus is the condition a constraint (or any modeling entity) reports when it cannot be fully evaluated — the public, Apache-2.0 form of the host's health vocabulary (model/health). A constraint whose geometry vanished goes Sick and is re-selectable; an over-constrained assembly that still solved reports Warning.

type HealthStatus uint8

const (
    // HealthOK: the entity is fully evaluated and valid.
    HealthOK HealthStatus = 0
    // HealthWarning: usable but flagged (e.g. redundant constraints that still solved).
    HealthWarning HealthStatus = 1
    // HealthSick: cannot be evaluated and needs user attention (e.g. a lost reference).
    HealthSick HealthStatus = 2
    // HealthSuppressed: intentionally excluded from evaluation by the user.
    HealthSuppressed HealthStatus = 3
)

func (HealthStatus) String​

func (h HealthStatus) String() string

String returns a stable lowercase name, byte-compatible with the host's health.Status.String() so the two vocabularies agree on the wire.

type HelicalShapeDefinitionKind​

HelicalShapeDefinitionKind discriminates how a helical curve's shape is specified (M06-F09, Oblikovati/Oblikovati#624). The wire spellings double as the helix Mode strings already accepted by sketch3d.addEntity since M22-F04.

The values are a frozen block matching the reference API's helical-shape definition enum; never renumber them.

type HelicalShapeDefinitionKind int32

const (
    // HelixShapePitchRevolution fixes pitch and turn count (height follows).
    HelixShapePitchRevolution HelicalShapeDefinitionKind = 115713
    // HelixShapePitchHeight fixes pitch and total height (turns follow).
    HelixShapePitchHeight HelicalShapeDefinitionKind = 115714
    // HelixShapeRevolutionHeight fixes turn count and total height (pitch follows).
    HelixShapeRevolutionHeight HelicalShapeDefinitionKind = 115715
    // HelixShapeSpiral is a flat spiral: no axial advance, radial growth per turn.
    HelixShapeSpiral HelicalShapeDefinitionKind = 115716
)

func ParseHelicalShapeDefinitionKind​

func ParseHelicalShapeDefinitionKind(s string) (HelicalShapeDefinitionKind, bool)

ParseHelicalShapeDefinitionKind resolves a wire spelling back to its kind.

func (HelicalShapeDefinitionKind) String​

func (k HelicalShapeDefinitionKind) String() string

String returns the shape kind's wire spelling.

type HelixEndKind​

HelixEndKind is the transition condition at one end of a helical curve (M06-F09). A natural end stops on the helix; a flat end appends a planar transition (governed by the definition's transition/flat angles) so the coil seats flat — the standard spring end treatment.

The values are a frozen block matching the reference API's helix-end enum; never renumber them.

type HelixEndKind int32

const (
    HelixEndNatural HelixEndKind = 115969
    HelixEndFlat    HelixEndKind = 115970
)

func ParseHelixEndKind​

func ParseHelixEndKind(s string) (HelixEndKind, bool)

ParseHelixEndKind resolves a wire spelling back to its kind.

func (HelixEndKind) String​

func (k HelixEndKind) String() string

String returns the end kind's wire spelling.

type HoleNoteQuantity​

HoleNoteQuantity is how hole notes treat multiple holes of the same size. The zero value is HoleNotePerHole (one callout per hole).

type HoleNoteQuantity int32

const (
    // HoleNotePerHole gives every hole its own diameter callout.
    HoleNotePerHole HoleNoteQuantity = iota
    // HoleNoteCombined groups holes by diameter into one "<n>x Ø<d>" callout per distinct diameter.
    HoleNoteCombined
)

func ParseHoleNoteQuantity​

func ParseHoleNoteQuantity(s string) (HoleNoteQuantity, bool)

ParseHoleNoteQuantity resolves a wire spelling back to its quantity mode.

q, ok := types.ParseHoleNoteQuantity("combined") // HoleNoteCombined, true

func (HoleNoteQuantity) String​

func (q HoleNoteQuantity) String() string

String returns the quantity mode's wire spelling ("perHole", "combined").

type IsotropyClass​

IsotropyClass declares a material's elastic symmetry, telling a structural (FEA) solver how to read its stiffness. An isotropic material is fully described by the scalar Mechanical group (E, ν); orthotropic and transversely-isotropic materials additionally carry an AnisotropicElastic group of direction-dependent constants. The zero value ("") is treated as Isotropic, so existing materials need no migration.

type IsotropyClass string

const (
    Isotropic             IsotropyClass = "isotropic"
    Orthotropic           IsotropyClass = "orthotropic"
    TransverselyIsotropic IsotropyClass = "transversely-isotropic"
)

func (IsotropyClass) Anisotropic​

func (c IsotropyClass) Anisotropic() bool

Anisotropic reports whether the class needs an AnisotropicElastic group — i.e. it is not isotropic. The empty class counts as isotropic.

type KeyChord​

KeyChord is a keyboard shortcut: a key token plus held modifiers. This is the canonical, Apache-2.0 definition shared by the typed client and the host's binding engine; the GPL implementation maps it onto its internal modifier bitmask. The canonical text form (KeyChord.String) is "Ctrl+Alt+Shift+Key" with the modifiers in that fixed order, so two chords are equal iff their String values match — that string is the comparison key the engine uses for conflict detection.

Example: KeyChord{Key: "E"}.String() == "E"; KeyChord{Key: "z", Ctrl: true}.String() == "Ctrl+Z".

type KeyChord struct {
    Key   string `json:"key"`
    Ctrl  bool   `json:"ctrl,omitempty"`
    Alt   bool   `json:"alt,omitempty"`
    Shift bool   `json:"shift,omitempty"`
}

func ParseChord​

func ParseChord(s string) (KeyChord, error)

ParseChord parses a canonical chord string into a KeyChord. The final '+'-separated token is the key; the rest are modifiers (case-insensitive: Ctrl/Control, Alt/Option, Shift). An empty string parses to the unbound zero chord; an empty key after modifiers or an unknown modifier is an error naming the offending input and the expected "[Ctrl+][Alt+][Shift+]Key" shape.

func (KeyChord) IsZero​

func (k KeyChord) IsZero() bool

IsZero reports whether the chord is unbound (no key) — the sentinel for "this action has no shortcut".

func (KeyChord) String​

func (k KeyChord) String() string

String renders the chord in canonical form ("Ctrl+Shift+E"). An unbound chord (empty key) renders as "".

type LightDefinitionTypeEnum​

LightDefinitionTypeEnum is the emission shape of a light: a directional (parallel-ray) sun, an omnidirectional point, or a cone spotlight. The numeric ids are stable, frozen values (53249–53251).

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.LightDefinitionTypeEnum) and maps it onto the renderer's LightKind.

type LightDefinitionTypeEnum int32

const (
    // DirectionalLight emits parallel rays (a sun); only its direction matters (53249).
    DirectionalLight LightDefinitionTypeEnum = 53249
    // PointLight emits from a position in all directions, with distance attenuation (53250).
    PointLight LightDefinitionTypeEnum = 53250
    // SpotLight emits from a position within a cone about its direction (53251).
    SpotLight LightDefinitionTypeEnum = 53251
)

func AllLightDefinitionTypes​

func (LightDefinitionTypeEnum) String​

func (t LightDefinitionTypeEnum) String() string

String returns the definition type's user-facing name.

type LightTypeEnum​

LightTypeEnum is the coordinate space a light lives in. A model-space light is fixed to the model; a view-space light follows the camera (a headlight); a ground-plane-space light is fixed to the ground/orientation-cube frame. The numeric ids are stable, frozen values (52993–52995).

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.LightTypeEnum) and maps it onto the renderer's lighting rig.

type LightTypeEnum int32

const (
    // ModelSpaceLight is fixed in model space (52993).
    ModelSpaceLight LightTypeEnum = 52993
    // ViewSpaceLight follows the camera — a headlight (52994).
    ViewSpaceLight LightTypeEnum = 52994
    // GroundPlaneSpaceLight is fixed to the ground-plane/ViewCube frame (52995).
    GroundPlaneSpaceLight LightTypeEnum = 52995
)

func (LightTypeEnum) String​

func (t LightTypeEnum) String() string

String returns the light type's user-facing name.

type LightingStyleTypeEnum​

LightingStyleTypeEnum says whether a lighting style is a traditional multi-light rig or an image-based (HDR environment) style. The numeric ids are stable, frozen values (50750977–50750978).

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.LightingStyleTypeEnum).

type LightingStyleTypeEnum int32

const (
    // StandardLightingStyle is a traditional rig of discrete lights (50750977).
    StandardLightingStyle LightingStyleTypeEnum = 50750977
    // ImageBasedLightingStyle derives illumination from an HDR environment image (50750978).
    ImageBasedLightingStyle LightingStyleTypeEnum = 50750978
)

func (LightingStyleTypeEnum) IsValid​

func (t LightingStyleTypeEnum) IsValid() bool

IsValid reports whether t is a defined lighting-style type.

func (LightingStyleTypeEnum) String​

func (t LightingStyleTypeEnum) String() string

String returns the lighting-style type's user-facing name.

type LineDefinitionSpaceEnum​

LineDefinitionSpaceEnum is the coordinate space a line graphic's width/pattern is defined in: screen space (constant pixels), model space (scales with zoom), or hybrid. Frozen ids 49921–49923.

type LineDefinitionSpaceEnum int32

const (
    // ScreenSpace defines line width in constant screen pixels (49921).
    ScreenSpace LineDefinitionSpaceEnum = 49921
    // ModelSpace defines line width in model units (scales with zoom) (49922).
    ModelSpace LineDefinitionSpaceEnum = 49922

AllLineDefinitionSpaces returns every defined line-definition space.

func (LineDefinitionSpaceEnum) IsValid​

func (l LineDefinitionSpaceEnum) IsValid() bool

IsValid reports whether l is a defined line-definition space.

func (LineDefinitionSpaceEnum) String​

func (l LineDefinitionSpaceEnum) String() string

String returns the line-definition-space's user-facing name.

type LoftAreaStop​

LoftAreaStop is one control point of a loft area graph (the kLoftWithAreaGraphSections mode): at fractional position T along the loft (0=start, 1=end) the cross-section's area is scaled by Scale (1 = unchanged). The graph is interpolated linearly between stops, so a stop set of {{0,1},{0.5,2},{1,1}} doubles the mid cross-section's area — a barrel controlled by area.

type LoftAreaStop struct {
    T     float64 `json:"t"`
    Scale float64 `json:"scale"`
}

type LoftCondition​

LoftCondition selects how a loft surface leaves the starting section (or arrives at the ending section) — the boundary tangency control that lets a loft curve away from a flat ruled blend. It mirrors the established loft-condition set: a free (natural) end, an angled takeoff measured against the section's sketch plane, tangency/curvature continuity with adjacent faces, and the point-section cases.

This is the canonical, Apache-2.0 definition; the GPL model aliases it (model/feature.LoftCondition = types.LoftCondition).

type LoftCondition string

const (
    // LoftFree imposes no tangency: the surface ends naturally, so a two-section Free loft is
    // ruled (a straight blend). Angle and impact are ignored.
    LoftFree LoftCondition = "free"
    // LoftAngle makes the surface leave the section at a fixed angle to the section's sketch
    // plane, weighted by an impact (takeoff weight). This is the control that curves a
    // two-section loft (e.g. a flared or necked transition).
    LoftAngle LoftCondition = "angle"
    // LoftDirection is an alias of LoftAngle (the angle/direction takeoff is one condition with
    // two exposed names).
    LoftDirection LoftCondition = "direction"
    // LoftTangent makes the surface tangent to the faces adjacent to the section (requires the
    // section to coincide with an existing body's edge).
    LoftTangent LoftCondition = "tangent"
    // LoftSmooth imposes curvature (G2) continuity with the adjacent faces.
    LoftSmooth LoftCondition = "smooth"
    // LoftG3 imposes curvature-rate (G3) continuity with the adjacent faces (a level beyond Smooth).
    LoftG3 LoftCondition = "g3"
    // LoftSharpPoint ends the loft in a sharp point (a point section).
    LoftSharpPoint LoftCondition = "sharp"
    // LoftTangentToPlane makes the surface tangent to a plane at a point section.
    LoftTangentToPlane LoftCondition = "tangent-to-plane"
)

func (LoftCondition) ContinuityOrder​

func (c LoftCondition) ContinuityOrder() int

ContinuityOrder is the geometric-continuity order a face-continuity condition imposes across the section edge: Tangent = 1 (G1), Smooth = 2 (G2), G3 = 3. Non-face conditions return 0.

func (LoftCondition) CurvesViaAngle​

func (c LoftCondition) CurvesViaAngle() bool

CurvesViaAngle reports whether the condition is the angle/direction takeoff — the case driven by an angle-to-plane and impact (the others need adjacent faces or point sections).

func (LoftCondition) IsFaceContinuity​

func (c LoftCondition) IsFaceContinuity() bool

IsFaceContinuity reports the conditions that continue an adjacent face's surface across the section edge: Tangent (G1), Smooth (G2) and G3. They require the section to be a body face.

func (LoftCondition) IsFree​

func (c LoftCondition) IsFree() bool

IsFree reports whether the condition leaves the end natural (the zero value "" is treated as Free, so an unset condition keeps the ruled/natural blend).

func (LoftCondition) IsPointCondition​

func (c LoftCondition) IsPointCondition() bool

IsPointCondition reports whether the condition applies to a point (apex) section.

func (LoftCondition) IsSharp​

func (c LoftCondition) IsSharp() bool

IsSharp reports the sharp-point point-section condition (a straight cone apex).

func (LoftCondition) IsTangentToPlane​

func (c LoftCondition) IsTangentToPlane() bool

IsTangentToPlane reports the tangent-to-plane point-section condition (a domed apex).

type LoftType​

LoftType is the loft mode — a plain blend through the sections, or one additionally guided by rails / a centerline / area-graph sections. It mirrors the established loft-type set.

This is the canonical, Apache-2.0 definition; the GPL model derives it (model/feature.LoftDefinition.LoftType()).

type LoftType string

const (
    // RegularLoft blends through the sections with no extra guides.
    RegularLoft LoftType = "regular"
    // LoftWithRails additionally constrains the surface to follow guide rails.
    LoftWithRails LoftType = "rails"
    // LoftWithCenterline sweeps the sections along a centerline (reserved).
    LoftWithCenterline LoftType = "centerline"
    // LoftWithAreaGraphSections places sections by an area graph along a centerline (reserved).
    LoftWithAreaGraphSections LoftType = "area-graph"
)

type Magnetic​

Magnetic groups a material's magnetic properties — the constitutive data a 2D/3D magnetostatics solver (e.g. the FEMM bridge add-in) needs to assign a block material. It serves both soft-magnetic cores and permanent magnets, distinguished by [Class]:

  • Soft-magnetic: RelativePermeability is the (initial/amplitude) μr and SaturationFluxDensity caps the linear region; Remanence/Coercivity are zero.
  • Hard-magnetic (PM): Remanence (Br) and Coercivity (Hc) define the demagnetisation line, and RelativePermeability is the recoil μr ≈ Br/(μ0·Hc) (typically ~1.05).

The zero value (Class == "", all fields 0) is a non-magnetic material; the solver treats it as free space (μr = 1). Existing materials therefore need no migration.

Example (NdFeB N42 permanent magnet):

Magnetic{Class: HardMagnetic, Remanence: 1.30, Coercivity: 915, RelativePermeability: 1.05}
type Magnetic struct {
    // Class selects the constitutive model (soft vs hard); "" == non-magnetic.
    Class MagneticClass `json:"class,omitempty" yaml:"class,omitempty"`
    // RelativePermeability is μr [-]: the amplitude permeability for a soft-magnetic core,
    // or the recoil permeability for a permanent magnet (≈ 1.05 for sintered NdFeB).
    RelativePermeability float64 `json:"relativePermeability,omitempty" yaml:"relativePermeability,omitempty"`
    // Remanence is the residual flux density Br [T] of a permanent magnet (0 for soft iron).
    Remanence float64 `json:"remanence,omitempty" yaml:"remanence,omitempty"`
    // Coercivity is the (intrinsic) coercive field Hc [kA/m] of a permanent magnet, the
    // field that drives B to zero — the demagnetisation margin a motor design checks.
    Coercivity float64 `json:"coercivity,omitempty" yaml:"coercivity,omitempty"`
    // SaturationFluxDensity is Bsat [T] where a soft-magnetic core leaves its linear region
    // (~1.5–2.0 T for electrical steels, ~2.3 T for cobalt iron). 0 when not applicable.
    SaturationFluxDensity float64 `json:"saturationFluxDensity,omitempty" yaml:"saturationFluxDensity,omitempty"`
    // CoreLoss is the specific iron loss at 1.5 T, 50 Hz [W/kg] of a lamination grade
    // (the W15/50 figure), for downstream loss estimation. 0 when unknown/not applicable.
    CoreLoss float64 `json:"coreLoss,omitempty" yaml:"coreLoss,omitempty"`
}

func (Magnetic) IsMagnetic​

func (m Magnetic) IsMagnetic() bool

IsMagnetic reports whether the material carries a meaningful magnetic model — i.e. it is soft- or hard-magnetic, not the non-magnetic default. A solver branches on this to decide whether to read the group or treat the region as free space.

type MagneticClass​

MagneticClass declares how a material responds to a magnetic field, telling a magnetostatics (FEA) solver which constitutive law to apply. The zero value ("") means the material is effectively non-magnetic (μr ≈ 1, no remanence), so the overwhelming majority of materials — plastics, woods, non-ferrous metals — carry no Magnetic group and need no migration. Only soft-magnetic cores and permanent magnets declare a class.

type MagneticClass string

const (
    // NonMagnetic is the default: μr ≈ 1, treated as free space by the solver.
    NonMagnetic MagneticClass = "non-magnetic"
    // SoftMagnetic is a linear/saturating core material (electrical steel, soft iron,
    // ferrite cores) — high permeability, negligible remanence. The solver reads
    // [Magnetic.RelativePermeability] (and saturates at SaturationFluxDensity).
    SoftMagnetic MagneticClass = "soft-magnetic"
    // HardMagnetic is a permanent magnet (NdFeB, SmCo, ferrite, AlNiCo): the solver reads
    // the linear-recoil model from [Magnetic.Remanence], [Magnetic.Coercivity] and the
    // recoil [Magnetic.RelativePermeability].
    HardMagnetic MagneticClass = "hard-magnetic"
)

type MassPropertiesAccuracy​

MassPropertiesAccuracy selects the tessellation fidelity a mass-properties computation uses — trading speed for accuracy on curved geometry (planar bodies are exact at any level). The zero value is MassPropertiesMedium.

type MassPropertiesAccuracy int32

const (
    // MassPropertiesMedium is the default tessellation fidelity.
    MassPropertiesMedium MassPropertiesAccuracy = iota
    // MassPropertiesLow is a coarse, faster tessellation.
    MassPropertiesLow
    // MassPropertiesHigh is a fine, slower tessellation for tighter accuracy on curved bodies.
    MassPropertiesHigh
)

ParseMassPropertiesAccuracy resolves a wire spelling back to its accuracy level.

func (MassPropertiesAccuracy) String​

func (a MassPropertiesAccuracy) String() string

String returns the accuracy level's wire spelling ("medium", "low", "high").

type MateConstraintSolutionType​

MateConstraintSolutionType discriminates how a mate between two directional faces resolves: opposed normals (a true mate) or aligned normals (a flush). It is the directed sense the solver enforces on the two faces' normals.

type MateConstraintSolutionType uint32

const (
    // MateSolutionOpposed is the default mate: the two face normals point at each other.
    MateSolutionOpposed MateConstraintSolutionType = 0
    // MateSolutionAligned is the flush sense: the two face normals point the same way.
    MateSolutionAligned MateConstraintSolutionType = 1
)

func (MateConstraintSolutionType) String​

func (s MateConstraintSolutionType) String() string

String returns a stable lowercase name.

type Matrix​

Matrix is a 4×4 affine 3D transform, row-major, with the bottom row expected to stay [0,0,0,1] (the builders guarantee it; a hand-built matrix is the caller's responsibility). JSON form: the 16 cells as one array.

type Mechanical​

Mechanical groups a material's structural properties. Units follow common mechanical-CAD conventions so values transfer 1:1 from existing material libraries. The yaml tags keep the on-disk document/library form readable (the tags are plain strings, so types still has no yaml dependency).

type Mechanical struct {
    YoungsModulus           float64 `json:"youngsModulus" yaml:"youngsModulus"`                     // GPa

    YieldStrength           float64 `json:"yieldStrength" yaml:"yieldStrength"`                     // MPa
    UltimateTensileStrength float64 `json:"ultimateTensileStrength" yaml:"ultimateTensileStrength"` // MPa
}

type MeshResolution​

MeshResolution selects the tessellation density of an exported mesh: coarser (low) to finer (high). It maps in the host to chord/angle tolerances — higher resolution yields more triangles for curved bodies (planar bodies are unaffected; they triangulate exactly). The zero value "" is treated as Medium.

Example:

req := wire.ExportRequest{Path: "p.stl", Format: "stl", Resolution: string(types.ResolutionHigh)}
type MeshResolution string

const (
    // ResolutionLow is a coarse preview density.
    ResolutionLow MeshResolution = "low"
    // ResolutionMedium is the default display density.
    ResolutionMedium MeshResolution = "medium"
    // ResolutionHigh is a fine print/CAM density.
    ResolutionHigh MeshResolution = "high"
)

func (MeshResolution) Normalized​

func (r MeshResolution) Normalized() MeshResolution

Normalized maps the zero value to Medium, leaving any explicit value unchanged, so callers can treat an unset resolution as the sensible default.

type MessageSeverity​

MessageSeverity grades a message-center entry (M05-F09, #616). The zero value is informational so a bare message is never accidentally an error.

type MessageSeverity uint8

const (
    // SeverityInfo is a neutral notice.
    SeverityInfo MessageSeverity = 0
    // SeverityWarning flags a recoverable problem the user should know about.
    SeverityWarning MessageSeverity = 1
    // SeverityError flags a failure; the message center's error state turns on.
    SeverityError MessageSeverity = 2
)

func (MessageSeverity) String​

func (m MessageSeverity) String() string

String returns the severity's stable name ("info", "warning", "error").

type MiniToolbarControlKind​

MiniToolbarControlKind is the kind of one declarative control on an in-canvas mini-toolbar — the MiniToolbarControlTypeEnum equivalent (M05-F07, #614). Like the dockable-window panel controls, a mini-toolbar is declared data the host renders, not a widget toolkit.

type MiniToolbarControlKind uint8

const (
    // MiniToolbarButton is a clickable button (the zero value); clicks arrive as
    // change events.
    MiniToolbarButton MiniToolbarControlKind = 0
    // MiniToolbarCheckbox is an on/off toggle.
    MiniToolbarCheckbox MiniToolbarControlKind = 1
    // MiniToolbarCombo is a pick-one dropdown of its Options.
    MiniToolbarCombo MiniToolbarControlKind = 2
    // MiniToolbarSlider is a numeric slider over [Min, Max].
    MiniToolbarSlider MiniToolbarControlKind = 3
    // MiniToolbarTextBox is a single-line text input.
    MiniToolbarTextBox MiniToolbarControlKind = 4
    // MiniToolbarValueEditor is a unit-aware numeric input: its text Value is an
    // expression the host's parameter engine evaluates ("12 mm", "width/2").
    MiniToolbarValueEditor MiniToolbarControlKind = 5
    // MiniToolbarTextEditor is a multi-line text input.
    MiniToolbarTextEditor MiniToolbarControlKind = 6
)

type ModelDiameterFromThread int32

const (
    ThreadMajorDiameter    ModelDiameterFromThread = 21761
    ThreadMinorDiameter    ModelDiameterFromThread = 21762
    ThreadPitchDiameter    ModelDiameterFromThread = 21763
    ThreadTapDrillDiameter ModelDiameterFromThread = 21764
)

func (ModelDiameterFromThread) String​

func (t ModelDiameterFromThread) String() string

type ModelValueType​

ModelValueType selects which value within a tolerance band the model actually consumes when recomputing (parity: ModelValueTypeEnum). The numeric values are frozen at the reference API's ids and must never be renumbered.

type ModelValueType int32

const (
    // ModelValueNominal uses the authored value, ignoring the tolerance band.
    ModelValueNominal ModelValueType = 31489
    // ModelValueLower uses nominal + the lower deviation.
    ModelValueLower ModelValueType = 31490
    // ModelValueUpper uses nominal + the upper deviation.
    ModelValueUpper ModelValueType = 31491
    // ModelValueMedian uses nominal + the midpoint of the deviation band.

func (ModelValueType) String​

func (m ModelValueType) String() string

String returns the model-value type's wire spelling.

type MoveOperationType​

MoveOperationType discriminates one entry in a Move feature's ordered operation list (M20·F20 parity). A move definition composes a sequence of independently parametric operations rather than a single baked transform, so "rotate 30° about this edge then slide 5 mm along it" round-trips as two separately driven operations. The reference API models these as typed operation objects (free-drag / move-along-ray / rotate-about-line) with no numeric enum; the string values are the stable wire vocabulary — treat them as frozen.

This is the canonical, Apache-2.0 definition; the GPL implementation maps each to its model operation builder.

type MoveOperationType string

const (
    // MoveFreeDrag offsets the body by explicit X/Y/Z distances.
    MoveFreeDrag MoveOperationType = "freeDrag"
    // MoveAlongRay slides the body a distance along a direction entity.
    MoveAlongRay MoveOperationType = "alongRay"
    // MoveRotateAboutLine rotates the body by an angle about an axis entity.
    MoveRotateAboutLine MoveOperationType = "rotateAboutLine"
)

func AllMoveOperationTypes​

func AllMoveOperationTypes() []MoveOperationType

AllMoveOperationTypes returns every move-operation type in definition order — the source list for a builder or a schema enum.

func (MoveOperationType) IsValid​

func (t MoveOperationType) IsValid() bool

IsValid reports whether t is a defined move-operation type.

type NewFileMetadata​

NewFileMetadata is the typed "new file" descriptor consumed by operations that mint a file the user never explicitly created — save-copy-as targets today; model-state and member exports later (M03-F09, Oblikovati/Oblikovati#610). Zero-value fields inherit from the source document of the operation.

type NewFileMetadata struct {
    // FileName is the target full file name, when the operation does not
    // already carry one.
    FileName string `json:"fileName,omitempty"`
    // DisplayName overrides the new file's display name.
    DisplayName string `json:"displayName,omitempty"`
    // TemplateFile seeds the new file from a template package.
    TemplateFile string `json:"templateFile,omitempty"`
    // SubType stamps the new file with a flavored document subtype id.
    SubType string `json:"subType,omitempty"`
}

type NormalBindingEnum​

NormalBindingEnum is how a primitive's normals bind to its geometry: per-vertex (smooth), per-strip, per-item, or one overall normal. Frozen ids 19713–19716.

type NormalBindingEnum int32

const (
    // PerVertexNormals binds one normal per vertex — smooth shading (19713).
    PerVertexNormals NormalBindingEnum = 19713
    // PerStripNormals binds one normal per strip (19714).
    PerStripNormals NormalBindingEnum = 19714
    // PerItemNormals binds one normal per item (19715).
    PerItemNormals NormalBindingEnum = 19715
    // OverallNormal binds one normal to the whole primitive (19716).
    OverallNormal NormalBindingEnum = 19716
)

IsValid reports whether n is a defined normal binding.

func (NormalBindingEnum) String​

func (n NormalBindingEnum) String() string

String returns the normal-binding's user-facing name.

type ObjectKind​

ObjectKind identifies the kind of document object a metadata-mutation event concerns (Oblikovati/Oblikovati#1644): a body, sketch, feature, occurrence, or the document itself. It is the discriminator carried by object.renamed and property.changed so ONE generic event serves every rename / property change instead of a bespoke event per mutation — an add-in matches on Kind to route the event to the right mirror of the document structure.

type ObjectKind string

const (
    // ObjectKindBody is a solid/surface body in a part.
    ObjectKindBody ObjectKind = "body"
    // ObjectKindSketch is a 2D or 3D sketch.
    ObjectKindSketch ObjectKind = "sketch"
    // ObjectKindFeature is a history feature (extrude, fillet, work plane, …).
    ObjectKindFeature ObjectKind = "feature"
    // ObjectKindOccurrence is an assembly component occurrence.
    ObjectKindOccurrence ObjectKind = "occurrence"
    // ObjectKindDocument is the document itself.
    ObjectKindDocument ObjectKind = "document"
)

type ObjectRef​

ObjectRef identifies one host-owned object across the contract: the numeric id every wire surface already hands out, qualified by the stable camelCase kind name ("sketchLine", "extrudeFeature", …) so heterogeneous collections stay self-describing (M00-F05, #601). The kind is an open string, not a frozen enum: each surface documents its kind names, and a collection can mix kinds the way the reference ObjectCollection mixes object types.

type ObjectRef struct {
    Kind string `json:"kind"`
    ID   uint64 `json:"id"`
}

func NewObjectRef​

func NewObjectRef(kind string, id uint64) ObjectRef

NewObjectRef builds a reference from a kind name and host id.

type OffsetCornerClosureType​

OffsetCornerClosureType selects how a planar wire offset closes a gap corner (Wire.OffsetPlanarWire).

type OffsetCornerClosureType int32

const (
    // CircularCornerClosure rounds the gap with an arc about the corner.
    CircularCornerClosure OffsetCornerClosureType = 96257
    // LinearCornerClosure extends both sides tangentially to a miter.
    LinearCornerClosure OffsetCornerClosureType = 96258
    // ExtendCornerClosure grows the actual curves (an arc stays an arc).
    ExtendCornerClosure OffsetCornerClosureType = 96259
)

func ParseOffsetCornerClosureType​

func (OffsetCornerClosureType) String​

func (c OffsetCornerClosureType) String() string

type OrbitTypeEnum​

OrbitTypeEnum is how the orbit gesture is constrained: a free (trackball) orbit or a constrained (turntable) orbit about vertical. Frozen ids 86017–86018.

const (
    // FreeOrbit is an unconstrained trackball orbit (86017).
    FreeOrbit OrbitTypeEnum = 86017
    // ConstrainedOrbit is a turntable orbit constrained about vertical (86018).
    ConstrainedOrbit OrbitTypeEnum = 86018
)

type OrientedBox​

OrientedBox is a box aligned to its own orthonormal frame: corner point plus three edge DIRECTIONS with per-axis extents (the reference's corner+vectors form, expressed with the unit/length split kept explicit).

type OrientedBox struct {
    Corner  Point      `json:"corner"`
    XAxis   UnitVector `json:"xAxis"`
    YAxis   UnitVector `json:"yAxis"`
    ZAxis   UnitVector `json:"zAxis"`
    Extents Vector     `json:"extents"` // edge lengths along the three axes
}

func (OrientedBox) Corners​

func (b OrientedBox) Corners() [8]Point

Corners returns the eight corner points.

type PanelControlKind​

PanelControlKind is the kind of one declarative control inside an add-in panel surface (a dockable window; also mini-toolbars, M05-F07). A panel is declared data the host renders, not a widget toolkit (M05-F03, #247). The editable kinds mirror a conventional mini-toolbar control set (check box / combo box / dropdown / value editor / slider / text box) so add-ins get a familiar form vocabulary. Each editable control carries an ID; when the user changes it the host pushes a [PanelValueChangedEvent] to the add-in.

type PanelControlKind uint8

const (
    // PanelLabel is a static text row (the zero value).
    PanelLabel PanelControlKind = 0
    // PanelButton is a clickable button that executes the command it names — the
    // add-in observes the click through the ordinary command-ended event.
    PanelButton PanelControlKind = 1
    // PanelSeparator is a horizontal rule between control groups.
    PanelSeparator PanelControlKind = 2
    // PanelTextBox is a single-line free-text input (Value = current text).
    PanelTextBox PanelControlKind = 3
    // PanelValueEditor is a unit-bearing numeric value editor for a dimension/parameter
    // (Value = a unit expression, e.g. "46.7 mm"); the natural input for parametric drivers.
    PanelValueEditor PanelControlKind = 4
    // PanelCheckBox is a boolean toggle (Value = "true"/"false").
    PanelCheckBox PanelControlKind = 5
    // PanelDropdown selects exactly one of Options (Value = the selected item).
    PanelDropdown PanelControlKind = 6
    // PanelComboBox is an editable dropdown: pick from Options or type a value (Value = text).
    PanelComboBox PanelControlKind = 7
    // PanelSlider is a bounded numeric slider (Value = number, bounded by Min/Max, step Step).
    PanelSlider PanelControlKind = 8
    // PanelGrid is a container that lays its Children out in a CSS-grid-like grid: Columns
    // declares the column tracks, each child may carry a Cell placement, otherwise children
    // auto-flow left-to-right wrapping at the column count (ADR-0019). Rows are content-height.
    PanelGrid PanelControlKind = 9
    // PanelGroup is a titled box (Title is the caption) that stacks its Children vertically —
    // the QGroupBox of this vocabulary.
    PanelGroup PanelControlKind = 10
    // PanelTabs is a tab strip: each direct child is one tab whose Title is the tab caption and
    // whose own content (typically a grid or group) is the pane.
    PanelTabs PanelControlKind = 11
    // PanelReferenceList is a list of picked host geometry references (faces/edges/
    // vertices) with host-driven Add-from-selection and per-row Remove. Rows holds the
    // current refs; Accepts limits which selection kinds may be added (empty = any).
    // Editing the rows pushes a [PanelReferencesChangedEvent] — NOT the scalar
    // PanelValueChangedEvent — because the value is a set, not one string.
    PanelReferenceList PanelControlKind = 12
)

func (PanelControlKind) String​

func (k PanelControlKind) String() string

String returns the kind's stable name.

type ParamAnomaly​

ParamAnomaly reports the irregularities of one parameter direction: whether the parameterization wraps (and with what period), hits singular points (a sphere pole, a cone apex, a polyline corner), or runs unbounded.

type ParamAnomaly struct {
    Periodic  bool    `json:"periodic,omitempty"`
    Period    float64 `json:"period,omitempty"`
    Singular  bool    `json:"singular,omitempty"`
    Unbounded bool    `json:"unbounded,omitempty"`
}

type ParameterDisplayFormat​

ParameterDisplayFormat is how a parameter's numeric value is rendered for display (parity: ParameterDisplayFormatEnum). It affects presentation only, never the stored or model value. The numeric values are frozen at the reference API's ids and must never be renumbered.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (ADR-0018).

type ParameterDisplayFormat int32

const (
    DisplayFormatDecimal       ParameterDisplayFormat = 92417
    DisplayFormatFractional    ParameterDisplayFormat = 92418

ParameterGroupKey is the immutable, locale-stable internal name that identifies a custom parameter group for its whole life (M02-F05, Oblikovati/Oblikovati#604). The editable, localizable display name lives beside it; persistence, wire methods, and membership all address a group by this key, so renaming the display never breaks references.

key := types.ParameterGroupKey("com.example.gears:ratios")
type ParameterGroupKey string

func (ParameterGroupKey) String​

func (k ParameterGroupKey) String() string

String returns the key's raw spelling.

type ParameterKind​

ParameterKind is a parameter's category, with stable explicit ids. Model/User/Table parameters are user-editable; Reference (driven by geometry) and Derived (linked from another document) are read-only.

type ParameterKind uint8

const (
    ModelParam     ParameterKind = 1
    UserParam      ParameterKind = 2
    ReferenceParam ParameterKind = 3
    DerivedParam   ParameterKind = 4
    TableParam     ParameterKind = 5
)

    ComputeIdentical PatternComputeType = 47361
    // ComputeAdjustToModel recomputes each occurrence against the model it lands on.
    ComputeAdjustToModel PatternComputeType = 47362
    // ComputeOptimized reuses one body transformed into place (lightest representation).

PhysicalProperties is the computed mass/geometry summary of a body or part given its material's density. Volume/area/centroid come from geometry; mass = density × volume. Lengths are in database units (cm), so volume is cm³, area cm², and — with density in g/cm³ — mass is grams.

type PhysicalProperties struct {
    Mass     float64    `json:"mass"`     // g
    Volume   float64    `json:"volume"`   // cm³
    Area     float64    `json:"area"`     // cm²

First consumed by the display-settings new-window default; the views surface reuses it. This is the canonical Apache-2.0 definition; the GPL implementation aliases it.

type ProjectionTypeEnum int32

const (
    // OrthographicProjection is a parallel (non-foreshortened) projection (86273).
    OrthographicProjection ProjectionTypeEnum = 86273

The values are a frozen block matching the reference API's reference-status enum; never renumber them.

type ReferenceStatus int32

const (
    // ReferenceUnknown means the reference has not been resolved yet (e.g. the
    // owning file was opened deferred and nothing probed the target).
    ReferenceUnknown ReferenceStatus = 49665
    // ReferenceUpToDate means the referenced file was found and matches what
    // the owner saved against.
    ReferenceUpToDate ReferenceStatus = 49666
    // ReferenceOutOfDate means the referenced file was found but has been
    // saved since the owner last recorded it.
    ReferenceOutOfDate ReferenceStatus = 49667
    // ReferenceMissing means the referenced file cannot be found at any
    // resolvable location.
    ReferenceMissing ReferenceStatus = 49668
    // ReferenceReplaced means the reference was re-pointed at another file
    // (a repair) and the owner has not been saved since.
    ReferenceReplaced ReferenceStatus = 49669
)

    // ReliefRound cuts a rounded (filleted) notch at the bend end — the gentlest on the
    // material and the default.
    ReliefRound ReliefShape = iota
    // ReliefSquare cuts a square notch — simplest to laser/punch, slightly more stress-prone.
    ReliefSquare
    // ReliefTear leaves no cut: the material tears along the bend end (no relief geometry).
    ReliefTear
)

func ParseReliefShape​

func ParseReliefShape(s string) (ReliefShape, bool)

ParseReliefShape resolves a wire spelling back to its relief shape.

func (ReliefShape) String​

func (r ReliefShape) String() string

func (k RepresentationKind) IsValid() bool

IsValid reports whether k names a real representation family (not unknown).

func (RepresentationKind) String​

func (k RepresentationKind) String() string

String returns a stable lowercase name. The value, not this name, is the persisted identity.

type Rgba​

Rgba is a straight-alpha color with each channel in [0,1] — the shape Dear ImGui (ImVec4) and the head's draw overlays ([4]float32) both consume, so a theme color crosses to the renderer without conversion. It is plain data; helpers parse/format the "#RRGGBB[AA]" hex used in theme files and on the wire.

This is the canonical, Apache-2.0 definition; the GPL theme package aliases it (theme.Rgba = types.Rgba) so the head and renderer share one color type.

type Rgba struct {
    R, G, B, A float32
}

func ParseHex​

func ParseHex(s string) (Rgba, error)

ParseHex reads "#RRGGBB" (alpha defaults to opaque) or "#RRGGBBAA" into an Rgba. It errors, naming the offending string, on a missing "#", a bad length, or non-hex digits — so a hand-edited theme file fails loudly rather than rendering black.

func (Rgba) Array​

func (c Rgba) Array() [4]float32

Array returns the color as the [4]float32 the head passes to ImGui and the renderer.

tint := theme.Color(types.TokenIconPrimary).Array() // [4]float32 for ImageButton

func (Rgba) Hex​

func (c Rgba) Hex() string

Hex formats the color as "#RRGGBBAA" (lower-case), the form stored in theme files.

type RibbonKey​

RibbonKey is the internal name of one of the host's ribbons. There is one ribbon per document type plus ZeroDoc (shown when no document is open); the active ribbon is selected by the active document. An add-in targets a ribbon by this name when placing a control. The names are stable wire values and must not be renamed.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (app.RibbonKey) so existing call sites are unaffected.

type RibbonKey string

const (
    // ZeroDocRibbon is shown when no document is open (the Get Started ribbon).
    ZeroDocRibbon RibbonKey = "ZeroDoc"
    // PartRibbon is shown for a part document.
    PartRibbon RibbonKey = "Part"
    // AssemblyRibbon is shown for an assembly document.
    AssemblyRibbon RibbonKey = "Assembly"
    // DrawingRibbon is shown for a drawing document.
    DrawingRibbon RibbonKey = "Drawing"
    // PresentationRibbon is shown for a presentation document.
    PresentationRibbon RibbonKey = "Presentation"
    // IFeaturesRibbon is shown for an iFeature authoring document.
    IFeaturesRibbon RibbonKey = "iFeatures"
    // UnknownDocumentRibbon is shown for a document whose type is not resolved.
    UnknownDocumentRibbon RibbonKey = "UnknownDocument"
)

func (RibbonKey) Valid​

func (k RibbonKey) Valid() bool

Valid reports whether k is one of the seven known ribbon names — used by the host to reject an add-in placing a control on a nonexistent ribbon.

type ScreenQuadrant​

ScreenQuadrant is one slot of a radial marking menu — the ScreenQuadrantEnum equivalent (M05-F12, #619): eight directions around the cursor, clockwise from north.

type ScreenQuadrant uint8

const (
    QuadrantNorth     ScreenQuadrant = 0
    QuadrantNorthEast ScreenQuadrant = 1
    QuadrantEast      ScreenQuadrant = 2
    QuadrantSouthEast ScreenQuadrant = 3
    QuadrantSouth     ScreenQuadrant = 4
    QuadrantSouthWest ScreenQuadrant = 5
    QuadrantWest      ScreenQuadrant = 6
    QuadrantNorthWest ScreenQuadrant = 7
)

func (ScreenQuadrant) String​

func (q ScreenQuadrant) String() string

String returns the quadrant's stable compass name.

type SectionPlane​

SectionPlane is a clipping plane carried by a design-view representation: a point on the plane and a normal. When the representation is active the half-space on the normal side is clipped away (Flipped swaps which side is removed), revealing the model's interior.

type SectionPlane struct {
    Origin  Point  `json:"origin"`
    Normal  Vector `json:"normal"`
    Flipped bool   `json:"flipped,omitempty"`
}

type ShadowDirectionEnum​

ShadowDirectionEnum is the light source that casts the scene's shadows: a fixed 45°/overhead direction, one of the four standard lights, or the environment image. The numeric ids are stable, frozen values (92161–92168).

This is the canonical Apache-2.0 definition; the GPL implementation aliases it (app.ShadowDirectionEnum).

type ShadowDirectionEnum int32

const (
    // FortyFiveDegreesLeftShadow casts from 45° to the left (92161).
    FortyFiveDegreesLeftShadow ShadowDirectionEnum = 92161
    // FortyFiveDegreesRightShadow casts from 45° to the right (92162).
    FortyFiveDegreesRightShadow ShadowDirectionEnum = 92162
    // AboveShadow casts straight down from above (92163).
    AboveShadow ShadowDirectionEnum = 92163
    // LightOneShadow follows light 1 (92164).
    LightOneShadow ShadowDirectionEnum = 92164
    // LightTwoShadow follows light 2 (92165).
    LightTwoShadow ShadowDirectionEnum = 92165
    // LightThreeShadow follows light 3 (92166).
    LightThreeShadow ShadowDirectionEnum = 92166
    // LightFourShadow follows light 4 (92167).
    LightFourShadow ShadowDirectionEnum = 92167
    // EnvironmentShadow follows the environment image's dominant light (92168).
    EnvironmentShadow ShadowDirectionEnum = 92168
)

type SheetOrientation int32

const (
    // SheetPortrait lays the sheet out with width ≤ height (the table's natural form).
    SheetPortrait SheetOrientation = iota

ParseSheetOrientation resolves a wire spelling back to its orientation.

func (SheetOrientation) String​

func (o SheetOrientation) String() string

String returns the orientation's wire spelling ("portrait" / "landscape").

type SheetSize​

SheetSize names a standard drawing sheet size. The zero value is SheetSizeCustom, whose dimensions come from the sheet's explicit width/height rather than the table.

Values are part of the wire contract via SheetSize.String; the names — not the ordinals — are what cross the wire, so reordering is safe but renaming is not.

type SheetSize int32

const (
    // SheetSizeCustom takes its dimensions from the sheet's explicit width/height.
    SheetSizeCustom SheetSize = iota
    // SheetSizeA0 is ISO 216 A0 (841×1189 mm).
    SheetSizeA0
    // SheetSizeA1 is ISO 216 A1 (594×841 mm).
    SheetSizeA1
    // SheetSizeA2 is ISO 216 A2 (420×594 mm).
    SheetSizeA2
    // SheetSizeA3 is ISO 216 A3 (297×420 mm).
    SheetSizeA3
    // SheetSizeA4 is ISO 216 A4 (210×297 mm).
    SheetSizeA4
    // SheetSizeAnsiA is ANSI/ASME Y14.1 A (8.5×11 in).
    SheetSizeAnsiA
    // SheetSizeAnsiB is ANSI/ASME Y14.1 B (11×17 in).
    SheetSizeAnsiB

sz, ok := types.ParseSheetSize("a3") // SheetSizeA3, true

func (SheetSize) String​

func (s SheetSize) String() string

String returns the sheet size's wire spelling ("a3", "ansiC", "custom").

type ShrinkwrapEnvelopeStyle​

ShrinkwrapEnvelopeStyle selects how kept parts are replaced by simpler proxy geometry — the reference API's envelopes-replace style. Envelopes erase internal detail (and, by construction, holes) so the result is a lightweight closed solid.

type ShrinkwrapEnvelopeStyle int32

const (
    // EnvelopeNone keeps each kept part's real geometry.
    EnvelopeNone ShrinkwrapEnvelopeStyle = iota
    // EnvelopePerPart replaces each kept part with its axis-aligned bounding box.

    EnvelopeWhole
)

func (ShrinkwrapEnvelopeStyle) String​

func (s ShrinkwrapEnvelopeStyle) String() string

type ShrinkwrapRemoveStyle int32

const (
    // RemoveNone keeps every part (the full, unsimplified set).
    RemoveNone ShrinkwrapRemoveStyle = iota
    // RemoveSmallParts drops parts whose body volume is below a threshold.
    RemoveSmallParts
    // RemoveInternalParts drops parts fully enclosed by other parts.
    RemoveInternalParts
)

func ParseShrinkwrapRemoveStyle​

func ParseShrinkwrapRemoveStyle(s string) (ShrinkwrapRemoveStyle, bool)

ParseShrinkwrapRemoveStyle resolves a wire spelling back to its ShrinkwrapRemoveStyle.

func (ShrinkwrapRemoveStyle) String​

func (s ShrinkwrapRemoveStyle) String() string

    Sketch3DEntitySplineHandle Sketch3DEntityKind = "splineHandle"
    Sketch3DEntityUnknown      Sketch3DEntityKind = "unknown"
)

type SketchEntityKind​

SketchEntityKind discriminates the kind of a 2D sketch entity in the wire protocol — the value of oblikovati.org/api/wire.AddSketchEntityArgs.Kind and of each enumerated entity's Kind. The set grows as M21 adds entity families (conics/splines, slots, polygons, …); the string values are frozen.

type SketchEntityKind string

    SketchEntityFillRegion         SketchEntityKind = "fillRegion"
    SketchEntityText               SketchEntityKind = "text"
    SketchEntityEquationCurve      SketchEntityKind = "equationCurve"
    SketchEntityFixedSpline        SketchEntityKind = "fixedSpline"

    // SketchEntitySplineHandle is the tangency handle attached to one fit
    // point of an interpolation spline (M06-F11, Oblikovati/Oblikovati#626).
    SketchEntitySplineHandle SketchEntityKind = "splineHandle"
    SketchEntityUnknown      SketchEntityKind = "unknown"
)

type SketchLineType​

SketchLineType is a sketch's line-style override. The empty value means "inherit the document default". String values are frozen.

type SketchLineType string

const (
    SketchLineContinuous SketchLineType = "continuous"
    SketchLineDashed     SketchLineType = "dashed"
    SketchLineHidden     SketchLineType = "hidden"
    SketchLineCenter     SketchLineType = "center"
    SketchLinePhantom    SketchLineType = "phantom"
    // SketchLineCustom is a definition loaded from an industry-standard .lin
    // line-type file via sketch.setCustomLineType; it is set by that method,
    // not directly through sketch.setProperty.
    SketchLineCustom SketchLineType = "custom"
)

type SketchPatternKind​

SketchPatternKind discriminates a sketch pattern. String values are frozen.

type SketchPatternKind string

const (
    SketchPatternRectangular SketchPatternKind = "rectangular"
    SketchPatternCircular    SketchPatternKind = "circular"
)

type SketchPointInferenceKind​

SketchPointInferenceKind describes how a placed sketch point was inferred from nearby geometry (M06-F10, Oblikovati/Oblikovati#625). This is the sketch-domain inference vocabulary; the host-level drag-snap kind stays in PointInferenceKind.

The values are a frozen block matching the reference API's point-inference enum; never renumber them.

type SketchPointInferenceKind int32

const (
    // SketchInferenceAtIntersection placed the point at two curves' crossing.
    SketchInferenceAtIntersection SketchPointInferenceKind = 22273
    // SketchInferenceOnCurve placed the point on a curve's body.
    SketchInferenceOnCurve SketchPointInferenceKind = 22274
    // SketchInferenceOnPoint snapped the point onto an existing sketch point.
    SketchInferenceOnPoint SketchPointInferenceKind = 22275
    // SketchInferenceAtMidpoint placed the point at a curve's midpoint.
    SketchInferenceAtMidpoint SketchPointInferenceKind = 22276
)

func ParseSketchPointInferenceKind​

func ParseSketchPointInferenceKind(s string) (SketchPointInferenceKind, bool)

ParseSketchPointInferenceKind resolves a wire spelling back to its kind.

func (SketchPointInferenceKind) String​

func (k SketchPointInferenceKind) String() string

String returns the inference kind's wire spelling.

type SketchSettings​

SketchSettings is a part document's persisted sketch-authoring defaults (#147) — the per-document surface of the Document Settings dialog's Sketch tab. It lifts the constraint-inference preferences that were previously session-only into the document (persisted in the .obk), so each part keeps its own: whether inference snaps points and auto-applies constraints while sketching, and which constraint family wins when two could apply. (3D-sketch and modeling settings are separate future objects; this starts with the inference toggles the sketch tools already read.)

type SketchSettings struct {
    // InferConstraints runs point snapping (endpoint → existing point, intersection, midpoint, …)
    // while sketching, surfacing inferred relations.
    InferConstraints bool `json:"inferConstraints"`
    // AutoApplyConstraints commits the inferred constraints automatically as geometry is placed
    // (off leaves the snap as a hint without persisting the relation).
    AutoApplyConstraints bool `json:"autoApplyConstraints"`
    // ConstraintPriority picks the constraint family when the inference engine could apply either.
    ConstraintPriority ConstraintInferencePriority `json:"constraintPriority"`
}

func DefaultSketchSettings​

func DefaultSketchSettings() SketchSettings

DefaultSketchSettings is the out-of-the-box configuration: inference and auto-apply on, with horizontal/vertical preferred — matching a new document's behaviour before this surface existed.

type SketchTextStyle​

SketchTextStyle is the renderable description of a sketch text entity: the content plus the type-setting parameters MCAD apps split across a text box + text style (font Family, FontSize in cm, the character Height in cm that scales the glyph em, the Rotation about the anchor in radians CCW, and horizontal/vertical alignment). It is the value carried by the wire DTOs and the typed client so an add-in can author/edit text without re-deriving the field set.

Example: SketchTextStyle{Content: "PART A", Family: "Liberation Sans", FontSize: 0.5, Height: 0.5, HAlign: TextAlignCenter, VAlign: TextAlignBaseline}.

type SketchTextStyle struct {
    Content  string              `json:"content"`
    Family   string              `json:"family,omitempty"`   // font family ("" ⇒ document default)
    FontSize float64             `json:"fontSize,omitempty"` // cm; 0 ⇒ track Height
    Height   float64             `json:"height"`             // character (em) height in cm
    Rotation float64             `json:"rotation,omitempty"` // radians CCW about the anchor
    HAlign   TextHorizontalAlign `json:"hAlign,omitempty"`
    VAlign   TextVerticalAlign   `json:"vAlign,omitempty"`
}

type SolutionNature​

SolutionNature classifies the solution set of a geometric query such as closest-point: how many equally good answers exist.

type SolutionNature int32

const (
    // UnknownSolutionNature means no solution strategy could be determined.
    UnknownSolutionNature SolutionNature = 0
    // UniqueSolution means there is exactly one solution.
    UniqueSolution SolutionNature = 1
    // DistinctlyManySolutions means finitely many, equally good solutions exist.
    DistinctlyManySolutions SolutionNature = 2
    // InfinitelyManySolutions means a continuum of equally good solutions exists
    // (e.g. the closest point to a circle queried from its center).
    InfinitelyManySolutions SolutionNature = 3
    // NoSolution means no solution exists.
    NoSolution SolutionNature = 4
)

func (SolutionNature) String​

func (n SolutionNature) String() string

String returns the classification's stable name.

type SplineFitMethod​

SplineFitMethod selects the parameterization an interpolation spline uses to fit its points (M06-F11, Oblikovati/Oblikovati#626). The default is SplineFitSmooth, which matches the behavior shipped before the field existed.

The values are a frozen block matching the reference API's spline-fit enum; never renumber them.

type SplineFitMethod int32

const (
    // SplineFitSmooth uses centripetal parameterization (the default).
    SplineFitSmooth SplineFitMethod = 26369
    // SplineFitSweet uses minimum-energy fitting.
    SplineFitSweet SplineFitMethod = 26370
    // SplineFitChord uses chord-length parameterization — the reference
    // API's third, legacy-drafting-compatible fit method.
    SplineFitChord SplineFitMethod = 26371
)

func ParseSplineFitMethod​

func ParseSplineFitMethod(s string) (SplineFitMethod, bool)

ParseSplineFitMethod resolves a wire spelling back to its method.

func (SplineFitMethod) String​

func (m SplineFitMethod) String() string

String returns the fit method's wire spelling.

type SplitType​

SplitType is the kind of split a split feature performed: trim a solid to one side of the tool, split its faces only (imprint), or split the body into separate solids. The reference declares kSplitPart sharing id 32769 with kTrimSolid; "trimSolid" is the canonical spelling here.

type SplitType int32

const (
    TrimSolidSplit  SplitType = 32769
    SplitFacesSplit SplitType = 32770
    SplitBodySplit  SplitType = 32771
)

func ParseSplitType​

func ParseSplitType(s string) (SplitType, bool)

ParseSplitType resolves a wire spelling back to its type.

func (SplitType) String​

func (t SplitType) String() string

String returns the split type's wire spelling.

type StartupActionType​

StartupActionType is what the application opens with — the StartupActionTypeEnum equivalent, narrowed to the actions the host implements (M05-F11, #618). The zero value preserves the historical behavior: a fresh part document ready to model in.

type StartupActionType uint8

const (
    // StartupNewPart opens a new part document at launch (the default).
    StartupNewPart StartupActionType = 0
    // StartupEmptyWorkspace opens with no document — the Get Started (ZeroDoc)
    // ribbon, for users who always begin from File ▸ Open.
    StartupEmptyWorkspace StartupActionType = 1
)

func (StartupActionType) String​

func (a StartupActionType) String() string

String returns the action's stable name ("new-part", "empty").

type StyleLocationEnum​

StyleLocationEnum is where a style lives in the cascade: in both the document and the style library, only locally in the document, or only in the library. A local style overrides the library style of the same name. The numeric ids are stable, frozen values (51201–51203).

This is the canonical Apache-2.0 definition; the GPL implementation aliases it.

type StyleLocationEnum int32

const (
    // BothStyleLocation: the style exists in both the document and the library (51201).
    BothStyleLocation StyleLocationEnum = 51201
    // LocalStyleLocation: the style exists only locally in the document (51202).
    LocalStyleLocation StyleLocationEnum = 51202
    // LibraryStyleLocation: the style exists only in the style library (51203).
    LibraryStyleLocation StyleLocationEnum = 51203
)

func AllStyleLocations​

func AllStyleLocations() []StyleLocationEnum

AllStyleLocations returns every defined style location.

func (StyleLocationEnum) IsValid​

func (s StyleLocationEnum) IsValid() bool

IsValid reports whether s is a defined style location.

func (StyleLocationEnum) String​

func (s StyleLocationEnum) String() string

String returns the style-location's user-facing name.

type SurfaceContinuity​

SurfaceContinuity is the geometric-continuity order a Class-A surfacing operation holds to its neighbours across a seam: G0 (position), G1 (tangent), G2 (curvature), G3 (curvature-rate). It is the public vocabulary for operations that take a continuity choice — the boundary fill (M36-F07), and reusable by match/extend. It is a string enum so it reads self-describingly on the wire; the kernel maps it to its internal derivative order via SurfaceContinuity.Order.

type SurfaceContinuity string

const (
    // ContinuityG0 holds position only (the surfaces meet at the seam; tangents may break).
    ContinuityG0 SurfaceContinuity = "g0"
    // ContinuityG1 holds tangency (a shared tangent plane along the seam).
    ContinuityG1 SurfaceContinuity = "g1"
    // ContinuityG2 holds curvature (no curvature jump across the seam) — the common Class-A choice.
    ContinuityG2 SurfaceContinuity = "g2"
    // ContinuityG3 holds curvature-rate (a level beyond G2).
    ContinuityG3 SurfaceContinuity = "g3"
)

func ParseSurfaceContinuity​

func ParseSurfaceContinuity(s string, fallback SurfaceContinuity) (SurfaceContinuity, bool)

ParseSurfaceContinuity resolves a wire spelling to a continuity; the empty string maps to the supplied fallback so a caller can pick its own default (e.g. the fill op defaults to G2).

func (SurfaceContinuity) Order​

func (c SurfaceContinuity) Order() int

Order returns the derivative order the continuity imposes: G0→0, G1→1, G2→2, G3→3. An empty or unrecognized value returns -1 (use ParseSurfaceContinuity to validate and default first).

func (SurfaceContinuity) String​

func (c SurfaceContinuity) String() string

String returns the continuity's wire spelling.

type SurfaceGeometryForm​

SurfaceGeometryForm is the surface representation classification (flag values, frozen to the reference).

type SurfaceGeometryForm int32

const (
    SurfaceFormClosedUVLoops     SurfaceGeometryForm = 1
    SurfaceFormNotClosedUVLoops  SurfaceGeometryForm = 2
    SurfaceFormNURBS             SurfaceGeometryForm = 4
    SurfaceFormNotNURBS          SurfaceGeometryForm = 8
    SurfaceFormProceduralToNURBS SurfaceGeometryForm = 16
)

type SurfaceType​

SurfaceType identifies a transient surface's concrete kind.

type SurfaceType int32

    BSplineSurfaceKind        SurfaceType = 5897
)

func (SurfaceType) String​

func (t SurfaceType) String() string

String returns the kind's stable name.

type SweepDefinitionType​

type SweepDefinitionType int32

const (
    PathSweepDef                 SweepDefinitionType = 59137
    PathAndGuideRailSweepDef     SweepDefinitionType = 59138
    PathAndGuideSurfaceSweepDef  SweepDefinitionType = 59139
    PathAndSectionTwistsSweepDef SweepDefinitionType = 59140
    // SolidSweepDef sweeps a tool BODY along the path (the reference
    // SolidSweepDefinition) — Oblikovati extension id.
    SolidSweepDef SweepDefinitionType = 59141
)

func ParseSweepDefinitionType​

func ParseSweepDefinitionType(s string) (SweepDefinitionType, bool)

ParseSweepDefinitionType resolves a wire spelling back to its type.

func (SweepDefinitionType) String​

func (t SweepDefinitionType) String() string

const (
    // NormalToPath keeps the profile perpendicular to the path tangent.
    NormalToPath SweepProfileOrientation = 59649
    // ParallelToOriginalProfile translates the profile without rotating it.
    ParallelToOriginalProfile SweepProfileOrientation = 59650
    // AlignToVector keeps the profile normal locked to a fixed vector.
    AlignToVector SweepProfileOrientation = 59651
)

func ParseSweepProfileOrientation​

func ParseSweepProfileOrientation(s string) (SweepProfileOrientation, bool)

ParseSweepProfileOrientation resolves a wire spelling back to its orientation.

func (SweepProfileOrientation) String​

func (o SweepProfileOrientation) String() string

String returns the orientation's wire spelling.

type SweepProfileScaling​

SweepProfileScaling controls how a guide rail scales the profile.

type SweepProfileScaling int32

const (
    // XYProfileScaling scales the whole section with the rail distance.
    XYProfileScaling SweepProfileScaling = 59393
    // XProfileScaling scales only along the rail direction.
    XProfileScaling SweepProfileScaling = 59394
    // NoProfileScaling lets the rail control orientation only.
    NoProfileScaling SweepProfileScaling = 59395
)

ParseSweepProfileScaling resolves a wire spelling back to its scaling.

func (SweepProfileScaling) String​

func (s SweepProfileScaling) String() string

String returns the scaling's wire spelling.

type SweepType​

SweepType is the placed feature's sweep kind (the SweepFeature property mirroring its definition type).

type SweepType int32

const (
    PathSweepType                SweepType = 104449
    PathAndGuideRailSweepType    SweepType = 104450
    PathAndGuideSurfaceSweepType SweepType = 104451
    PathAndSectionTwistSweepType SweepType = 104452
)

func ParseSweepType​

func ParseSweepType(s string) (SweepType, bool)

ParseSweepType resolves a wire spelling back to its type.

func (SweepType) String​

func (t SweepType) String() string

String returns the sweep type's wire spelling.

type TextHorizontalAlign​

TextHorizontalAlign is how sketch text is positioned horizontally about its anchor point (left/center/right, the standard MCAD horizontal text alignments). String values are frozen — they appear in the .obk document and on the wire.

type TextHorizontalAlign string

const (
    TextAlignLeft   TextHorizontalAlign = "left"
    TextAlignCenter TextHorizontalAlign = "center"
    TextAlignRight  TextHorizontalAlign = "right"
)

type TextVerticalAlign​

TextVerticalAlign is how sketch text is positioned vertically about its anchor point (baseline/lower/middle/upper, the standard MCAD vertical text alignments). Baseline keeps the text's baseline on the anchor; the others measure from the text's cap box. String values are frozen.

type TextVerticalAlign string

const (
    TextAlignBaseline TextVerticalAlign = "baseline" // baseline on the anchor (sketch-text default)
    TextAlignLower    TextVerticalAlign = "lower"    // text below the anchor
    TextAlignMiddle   TextVerticalAlign = "middle"   // cap box centred on the anchor
    TextAlignUpper    TextVerticalAlign = "upper"    // text above the anchor
)

type ThemeKind​

ThemeKind classifies a theme as one of the two shipped built-ins or a user copy. It picks the right default seed and tells the editor which themes are read-only (built-ins) versus editable (custom).

type ThemeKind string

const (
    ThemeLight  ThemeKind = "light"
    ThemeDark   ThemeKind = "dark"
    ThemeCustom ThemeKind = "custom"
)

func (ThemeKind) Editable​

func (k ThemeKind) Editable() bool

Editable reports whether the user may recolor a theme of this kind (only customs).

type ThemeToken​

ThemeToken names one semantic color slot of the UI theme — the curated, stable vocabulary the host styles itself from and add-ins read to match the host's look. One token may drive several concrete Dear ImGui colors (e.g. ChromeAccent feeds the active tab, the checkmark, and the slider grab), keeping the user-facing palette small. The string values are the wire/file keys; treat them as frozen.

Tokens cover the application shell only — window, menus, viewport 2D overlays, and 3D gizmos. They deliberately do NOT cover 3D body appearance, which the material/ appearance subsystem owns.

type ThemeToken string

Chrome — the windowed shell drawn by Dear ImGui (menus, panels, ribbon, controls).

const (
    TokenChromeWindowBg      ThemeToken = "chrome.window_bg"
    TokenChromePanelBg       ThemeToken = "chrome.panel_bg"
    TokenChromePopupBg       ThemeToken = "chrome.popup_bg"
    TokenChromeMenuBarBg     ThemeToken = "chrome.menu_bar_bg"
    TokenChromeHeaderBg      ThemeToken = "chrome.header_bg"
    TokenChromeText          ThemeToken = "chrome.text"
    TokenChromeTextDisabled  ThemeToken = "chrome.text_disabled"
    TokenChromeBorder        ThemeToken = "chrome.border"
    TokenChromeControlBg     ThemeToken = "chrome.control_bg"
    TokenChromeControlHover  ThemeToken = "chrome.control_hover"
    TokenChromeControlActive ThemeToken = "chrome.control_active"
    TokenChromeButton        ThemeToken = "chrome.button"
    TokenChromeButtonHover   ThemeToken = "chrome.button_hover"
    TokenChromeButtonActive  ThemeToken = "chrome.button_active"
    TokenChromeAccent        ThemeToken = "chrome.accent"
    TokenChromeScrollbar     ThemeToken = "chrome.scrollbar"
    // TokenChromeDanger flags an error/required affordance — e.g. a feature panel's
    // required-but-empty selector outline, or a validation message.
    TokenChromeDanger ThemeToken = "chrome.danger"
)

Viewport 2D — the sketch/grid/dimension overlays drawn into the 3D view.

const (
    TokenViewportBg       ThemeToken = "viewport.bg"
    TokenGridMinor        ThemeToken = "viewport.grid_minor"
    TokenGridMajor        ThemeToken = "viewport.grid_major"
    TokenGridAxis         ThemeToken = "viewport.grid_axis"
    TokenSketchGeometry   ThemeToken = "viewport.sketch_geometry"
    TokenSketchSelected   ThemeToken = "viewport.sketch_selected"
    TokenSketchCandidate  ThemeToken = "viewport.sketch_candidate"
    TokenSketchPreview    ThemeToken = "viewport.sketch_preview"
    TokenDimensionDriving ThemeToken = "viewport.dimension_driving"
    TokenDimensionDriven  ThemeToken = "viewport.dimension_driven"
    TokenSnapGlyph        ThemeToken = "viewport.snap_glyph"
    // TokenViewportActiveBorder is the outline drawn around the focused view tile in a
    // split (multi-view) layout, so the user can tell which view is active.
    TokenViewportActiveBorder ThemeToken = "viewport.active_border"
)

Gizmos 3D — manipulator/affordance geometry (work planes, selection highlight).

const (
    TokenPlaneFaint         ThemeToken = "gizmo.plane_faint"
    TokenPlaneHover         ThemeToken = "gizmo.plane_hover"
    TokenPlaneSelected      ThemeToken = "gizmo.plane_selected"
    TokenSelectionHighlight ThemeToken = "gizmo.selection_highlight"
    // TokenPlaneFill is the translucent fill of a work plane's display square — its
    // alpha sets how see-through the plane is, so the user configures the look here.
    TokenPlaneFill ThemeToken = "gizmo.plane_fill"
)

Icons — ribbon glyphs. An icon carries up to four color roles: primary main linework, secondary accent (the action/result element of the glyph), tertiary supporting detail (anchors, construction marks), and a background plate. Each role rasterizes to its own mask and is colored from these tokens when the theme applies, so one glyph set follows every theme.

const (
    TokenIconPrimary    ThemeToken = "icon.primary"
    TokenIconSecondary  ThemeToken = "icon.secondary"
    TokenIconTertiary   ThemeToken = "icon.tertiary"
    TokenIconBackground ThemeToken = "icon.background"
)

func AllThemeTokens​

func AllThemeTokens() []ThemeToken

AllThemeTokens lists every token once, in display order (Chrome, Viewport, Gizmos, Icons). A complete theme palette defines a color for each; the editor iterates this to render its grouped color rows. Keep new tokens appended to their group.

type Thermal​

Thermal groups a material's heat-related properties.

type Thermal struct {
    Conductivity   float64 `json:"conductivity" yaml:"conductivity"`     // W/(m·K)
    ExpansionCoeff float64 `json:"expansionCoeff" yaml:"expansionCoeff"` // 1/K (linear)
    SpecificHeat   float64 `json:"specificHeat" yaml:"specificHeat"`     // J/(kg·K)
}

type ThumbnailSaveOption​

ThumbnailSaveOption controls whether and how a preview thumbnail is captured when a document is saved (M03-F09, Oblikovati/Oblikovati#610). Thumbnails are git-ignored sidecar images, never document content (ADR-0020).

The values are a frozen block matching the reference API's thumbnail-save enum; never renumber them. A host may implement a subset and reject the rest when the save options are written.

type ThumbnailSaveOption int32

const (
    // ThumbnailNone captures no thumbnail.
    ThumbnailNone ThumbnailSaveOption = 79873
    // ThumbnailIsoViewOnSave captures the isometric view at save time.
    ThumbnailIsoViewOnSave ThumbnailSaveOption = 79874
    // ThumbnailActiveWindowOnSave captures the active viewport at save time.
    ThumbnailActiveWindowOnSave ThumbnailSaveOption = 79875
    // ThumbnailActiveWindow captures the active viewport immediately.
    ThumbnailActiveWindow ThumbnailSaveOption = 79876
    // ThumbnailImportFromFile uses a caller-supplied image file.
    ThumbnailImportFromFile ThumbnailSaveOption = 79877
)

func ParseThumbnailSaveOption​

func ParseThumbnailSaveOption(s string) (ThumbnailSaveOption, bool)

ParseThumbnailSaveOption resolves a wire spelling back to its option.

func (ThumbnailSaveOption) String​

func (o ThumbnailSaveOption) String() string

String returns the thumbnail option's wire spelling.

type Tolerance​

Tolerance is an engineering tolerance: a flavor plus the deviation band from the nominal value (Upper, Lower, database units). The zero Tolerance means "standard/default tolerance, no explicit band"; Tolerance.Kind maps the zero Type onto ToleranceDefault, so a `t != Tolerance{}` has-explicit-tolerance check keeps working. Which value within the band the model consumes is the parameter's ModelValueType (the reference API splits Tolerance.ToleranceType from Parameter.ModelValueType).

type Tolerance struct {
    Type  ToleranceType
    Upper float64
    Lower float64
}

func (Tolerance) Kind​

func (t Tolerance) Kind() ToleranceType

Kind returns the tolerance flavor, mapping the zero value to ToleranceDefault.

type ToleranceType​

ToleranceType is the engineering-tolerance flavor attached to a parameter or dimension (parity: ToleranceTypeEnum). The numeric values are frozen at the reference API's ids and must never be renumbered.

This is the canonical, Apache-2.0 definition; the GPL implementation aliases it (ADR-0018).

type ToleranceType int32

const (
    ToleranceDefault                 ToleranceType = 31233
    ToleranceOverride                ToleranceType = 31234
    ToleranceSymmetric               ToleranceType = 31235
    ToleranceDeviation               ToleranceType = 31236
    ToleranceLimitsStacked           ToleranceType = 31237
    ToleranceLimitLinear             ToleranceType = 31238
    ToleranceMax                     ToleranceType = 31239
    ToleranceMin                     ToleranceType = 31240
    ToleranceLimitsFitsStacked       ToleranceType = 31241
    ToleranceLimitsFitsLinear        ToleranceType = 31242
    ToleranceLimitsFitsShowSize      ToleranceType = 31243
    ToleranceLimitsFitsShowTolerance ToleranceType = 31244
    ToleranceBasic                   ToleranceType = 31245
    ToleranceReference               ToleranceType = 31246
)

func ParseToleranceType​

func ParseToleranceType(s string) (ToleranceType, bool)

ParseToleranceType resolves a wire spelling back to its ToleranceType.

func (ToleranceType) String​

func (t ToleranceType) String() string

String returns the tolerance type's wire spelling.

type TransactionPoint​

TransactionPoint identifies a position on a document's transaction stream relative to the cursor — which step a transaction event or navigation acts on. A committed edit acts on the current point, undo acts on the previous one, redo on the next (M04-F05, Oblikovati/Oblikovati#613).

The values are a frozen block matching the reference API's transaction-point enum; never renumber them.

type TransactionPoint int32

const (
    // TransactionPointUnknown is the sentinel for "no particular step" (e.g.
    // a whole stream being deleted on document close).
    TransactionPointUnknown TransactionPoint = 3585
    // TransactionPointNext is the step ahead of the cursor (what redo acts on).
    TransactionPointNext TransactionPoint = 3586
    // TransactionPointPrevious is the step behind the cursor (what undo acts on).
    TransactionPointPrevious TransactionPoint = 3587
    // TransactionPointCurrent is the step at the cursor (what a commit produced).
    TransactionPointCurrent TransactionPoint = 3588
    // TransactionPointUpToSpecified addresses a span of steps up to a named one
    // (multi-step undo navigation).
