class Ifc4x2::IfcVertex : public Ifc4x2::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.
