class Ifc4::IfcSubedge : public Ifc4::IfcEdge

Definition from ISO/DIS 10303-42:1999(E): A subedge is an edge whose domain is a connected portion of the domain of an existing edge. The topological constraints on a subedge are the same as those on an edge.

Informal propositions:

The domain of the subedge is formally defined to be the domain of the parent edge, as trimmed by the subedge start vertex and subedge end vertex. The start vertex and end vertex shall be within the union of the domains of the vertices of the parent edge and the domain of the parent edge.

NOTE Corresponding ISO 10303 entity: subedge. Please refer to ISO/DIS 10303-42:1999(E), p. 194 for the final definition of the formal standard.
