I'm to so familiar with the underlying geometries behind TopoDS Shells so I have this problem:
I intersect to shells to find the intersection lines. Now I want to cut away a peace of one of the shells by this intersection line(s). but because these lines dont need hit the outer wire of my shell I must extend the intersection line.
So, can anybody tell me how I can get a line ON A SURFACE out of two point which are on the surface.
Thanks a lot
