ISO 10303-214:2010(E)
An Edge_loop is a closed loop made up of a sequence of edges. In this sequence the start vertex of an edge coincides with the end vertex of its preceding edge and the first vertex of the Edge_loop coincides with the last vertex.
NOTE The Edge_loop is used for topological representation.
The data associated with an Edge_loop are the following:
edge
The edge specifies the edges that compose the Edge_loop.
See edge_loop to oriented_edge_curve for the application assertion.
