Class Documentation

class Ifc2x3::IfcSurface : public Ifc2x3::IfcGeometricRepresentationItem

Definition from ISO/CD 10303-42:1992: A surface can be envisioned as a set of connected points in 3-dimensional space which is always locally 2-dimensional, but need not be a manifold.

NOTE Corresponding ISO 10303 entity: surface, the following subtypes have been incorporated into IFC - elementary_surface (as IfcElementarySurface), swept_surface (as IfcSweptSurface) and bounded_surface (as IfcBoundedSurface). Please refer to ISO/IS 10303-42:1994, p. 68 for the final definition of the formal standard.

HISTORY New class in IFC Release 1.5

Informal proposition:

A surface has non zero area. A surface is arcwise connected.

Subclassed by Ifc2x3::IfcBoundedSurface, Ifc2x3::IfcElementarySurface, Ifc2x3::IfcSweptSurface
