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
