Enum SurfaceKind 

pub enum SurfaceKind {
    Plane,
    CylindricalSurface,
    SphericalSurface,
    ToroidalSurface,
    SurfaceOfLinearExtrusion,
    SurfaceOfRevolution,
    CurveBoundedPlane,
    CurveBoundedSurface,
    RectangularTrimmedSurface,
    BSplineSurface,
    BSplineSurfaceWithKnots,
    RationalBSplineSurfaceWithKnots,
}

Which IfcSurface subtype an entity is.

Dispatch on the type name once, then construct the matching view. Returning None rather than an error keeps “not a surface” separate from “a surface we cannot read”, which callers scanning a representation need.

Variants

Plane

IfcPlane.

CylindricalSurface

IfcCylindricalSurface.

SphericalSurface

IfcSphericalSurface.

ToroidalSurface

IfcToroidalSurface.

SurfaceOfLinearExtrusion

IfcSurfaceOfLinearExtrusion.

SurfaceOfRevolution

IfcSurfaceOfRevolution.

CurveBoundedPlane

IfcCurveBoundedPlane.

CurveBoundedSurface

IfcCurveBoundedSurface.

RectangularTrimmedSurface

IfcRectangularTrimmedSurface.

BSplineSurface

IfcBSplineSurface and its non-knotted form.

BSplineSurfaceWithKnots

IfcBSplineSurfaceWithKnots.

RationalBSplineSurfaceWithKnots

IfcRationalBSplineSurfaceWithKnots.

Implementations

impl SurfaceKind

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

Classify by IFC type name, None if not an IfcSurface subtype.

pub fn is_elementary(self) -> bool

Is this an IfcElementarySurface?

The distinguishing property is not “analytic” but unbounded: these are the surfaces that need a container to supply their extent.

pub fn is_bounded(self) -> bool

Is this an IfcBoundedSurface?

The only branch that carries its own extent, so the only branch that can be meshed without asking its container how far to go.

pub fn is_swept(self) -> bool

Is this an IfcSweptSurface?

pub fn has_basis_surface(self) -> bool

Does this surface delegate its shape to another surface?

True for the trimming and curve-bounding wrappers, whose BasisSurface must be resolved before anything can be evaluated. A consumer that does not follow the chain silently drops the geometry.
