IfcVertex: public Ifc4x1::IfcTopologicalRepresentationItem¶
Definition from ISO/CD 10303-42:1992: A vertex is the topological construct corresponding to a point. It has dimensionality 0 and extent 0. The domain of a vertex, if present, is a point in m dimensional real space RM; this is represented by the vertex point subtype.
NOTE Corresponding ISO 10303 entity: vertex. Please refer to ISO/IS 10303-42:1994, p. 129 for the final definition of the formal standard.
HISTORY New Entity in IFC Release 2.0
