Neat, what sort of feature recognition are you looking into doing? Any particular use? > 1. determination of surface type(cylinder/sphere/plane/freeform) from IGES > file. I don't know how to do this yet, I'll admit. :-) > 2. determination of edge type(convex/concave/tangent). I think I remember seeing this as a method of TopoDS_Face surfaces, or something.

You can probably do this by importing math and retrieving the coordinates of various points. Check into the OCC.Utilities.Topology stuff. > 5. extraction of axis of a cylindrical surface. Look into the gp_Axis() classes. > 6. creation of a cylinder. You can find that in cylinder.py, an example script distributed with pythonOCC. - Bryan http://heybryan.org/ 1 512 203 0507 _______________________________________________ Pythonocc-users mailing list Pythonocc-users@gna.org https://mail.gna.org/listinfo/pythonocc-users
