Do you plan to extend your > project beyond CSG features? The main reason I switched to PythonOCC is, I couldn't get past assertion failures and crashes with CGAL, even while performing CSG operations on some simple geometries. Probably my lack of understanding of CGAL, but I was blocked nonetheless. With PythonOCC features however I got things working in only couple of days. Never faced in crashes, or incurred errors that I couldn't understand. In near term I am interested only in CSG operations, but in future I would like to add more functionality. Could you please elaborate on why you said switch from CGAL to PythonOCC may be hazardous? The Polyhedron class in cadmium is roughly an equivalent of BRepPrimitive in PythonOCC (or Nef_Polyhedron when it was using CGAL). Do you think that may be an incorrect abstraction? I see that PythonOCC has support for a lot of features (NURBs, arbitrary BRep construction, etc), I believe we can come up with simple abstractions on top of these powerful features to provide some cool solid modeling functionality.

I sure will. Thanks for the feedback. _______________________________________________ Pythonocc-users mailing list Pythonocc-users@gna.org https://mail.gna.org/listinfo/pythonocc-users
