Oh I see what you are saying. This answers some questions I had. IIUC, you are saying that the name Polyhedron implies only topology, which sphere and cylinder are topology+geometry. Is that correct? I didn't think about that while naming the base class Polyhedron. I think I should rename it to "Primitive". Does that sound ok? Moreover could you tell me, is there a way for me to get only the topology of sphere/cylinder? As you said, they are tesselations, so OpenCASCADE does its best to generate as smooth a surface as possible to match the real curvature. But this results in lot of polygons. What option do I have to limit or control the number of polygons in the tesselations? Thanks for clarifying this. _______________________________________________ Pythonocc-users mailing list Pythonocc-users@gna.org https://mail.gna.org/listinfo/pythonocc-users
