Hi Dalton, Does python tell you which line it doesn't like?
>From the TypeError, it seems like it would be this line: steptopo = TopoDS_Face(BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e- 6).Shape()) If so, try breaking the line into parts: brep = BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-6).Shape() steptopo = TopoDS_Face(brep) I would imagine the error would then be on the second of these lines. If so, try displaying brep with the simpleGUI to make sure it looks like a face (a surface bounded by a wire). If the display doesn't look right, there's something wrong with your surface. Let me know what you find, and we'll go from there. - Charles _______________________________________________ Pythonocc-users mailing list Pythonocc-users@gna.org https://mail.gna.org/listinfo/pythonocc-users
