How one representation item models its shape.

Finer than crate::solid::SolidKind, which groups every sweep as Swept: a rule check that allows extrusions but not directrix sweeps needs the distinction. The concrete IFC type is reported beside the kind, so a caller that needs more detail than the kind states can read it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Extrusion

IfcExtrudedAreaSolid: a profile swept along a straight direction.

TaperedExtrusion

IfcExtrudedAreaSolidTapered: an extrusion lofted to an end profile.

Revolution

IfcRevolvedAreaSolid: a profile swept about an axis.

TaperedRevolution

IfcRevolvedAreaSolidTapered: a revolution lofted to an end profile.

DirectrixSweep

IfcFixedReferenceSweptAreaSolid or IfcSurfaceCurveSweptAreaSolid: a profile swept along a directrix curve.

SweptDisk

IfcSweptDiskSolid or IfcSweptDiskSolidPolygonal: a circular disk swept along a curve.

SectionedSpine

IfcSectionedSpine: cross sections interpolated along a spine.

Brep

A faceted or advanced boundary representation, with or without voids.

Csg

IfcCsgSolid, IfcBooleanResult or IfcBooleanClippingResult: a boolean tree.

CsgPrimitive

A CSG primitive: IfcBlock, IfcSphere, IfcRightCircularCylinder, IfcRightCircularCone or IfcRectangularPyramid.

HalfSpace

A half space. Infinite; only meaningful as a boolean operand.

BoundingBox

IfcBoundingBox: a proxy extent, not a shape.

Tessellated

IfcTriangulatedFaceSet or IfcPolygonalFaceSet.

SurfaceModel

IfcShellBasedSurfaceModel or IfcFaceBasedSurfaceModel. Never a solid, even when every shell is closed.

Face

IfcFaceSurface or IfcAdvancedFace: one bounded face on a carrier surface. Never a solid: a single face encloses nothing.

GeometricSet

IfcGeometricSet or IfcGeometricCurveSet.

Curve

Any IfcCurve.

Surface

Any IfcSurface.

Point

IfcPointOnCurve or IfcPointOnSurface.

Implementations

impl BodyKind

pub fn classify(type_name: &str) -> Option<Self>

None for IfcMappedItem (resolved, not classified) and for anything that is not a representation item family this crate interprets.

pub fn is_swept_area(self) -> bool

Is this a swept-area family, whose profile crate::SweptSolid describes?
