class Ifc4::IfcEdgeLoop : public Ifc4::IfcLoop

Definition from ISO/CD 10303-42:1992: An edge_loop is a loop with nonzero extent. It is a path in which the start and end vertices are the same. Its domain, if present, is a closed curve. An edge_loop may overlap itself.

Informal propositions:

The genus of the IfcEdgeLoop shall be 1 or greater. The Euler formula shall be satisfied:(number of vertices) + genus - (number of edges) = 1; No edge may be referenced more than once by the same IfcEdgeLoop with the same sense. For this purpose, an edge which is not an oriented edge is considered to be referenced with the sense TRUE.

NOTE Corresponding ISO 10303 entity: edge_loop. Please refer to ISO/IS 10303-42:1994, p. 122 for the final definition of the formal standard.
