Open CASCADE classes respecting/ignoring edge orientation
Class Supports Orientation Description
Poly_PolygonOnTriangulation No The polygon you get from the triangulation of an edge/face does not provide the vertices in the order they appear in the edge but in the curve. So for a reversed edge, the vertices appear in reversed order
BRepAdaptor_Curve No The edge is traversed along the curve's orientation. A possible reversed orientation of the edge is ignored
