I am linking OCC with an external mesher.
To do so, for each face of a solid, I have to know an orientation :
taking the first edge of this face, I have to know wether the face is on the left or on the right of this edge.
I tried to use the Orientation() method of TopoDS_Edge, but it gives sometimes the right result, sometimes not.
So I assume that there is something related with the orientation of the underlying Geom2d_Curve ?
Can someone explain me how to get this information ?
