Hello

Does anyone know a similar function to BRepAlgoAPI_Common? I want to get the common Surface of two shapes.
With BRepAlgoAPI_Common, the calculation last al least 2 or 3 minutes. Thats much to long for my Application.
I also tried BRepAlgo_Common. This is much faster, but the result is not really correct.

Regards
Joachim
