class Ifc4x2::IfcVertexLoop : public Ifc4x2::IfcLoop

Definition from ISO/CD 10303-42:1992: A vertex_loop is a loop of zero genus consisting of a single vertex. A vertex can exist independently of a vertex loop. The topological data shall satisfy the following constraint:

Informal propositions:

A vertex loop has zero extent and dimensionality. The vertex loop has genus 0.

NOTE Corresponding ISO 10303 entity: vertex_loop. Please refer to ISO/IS 10303-42:1994, p. 121 for the final definition of the formal standard.
