BRepAlgoApi_Common: Strange output between solid and shape

Davide Canalia's picture
Forums: 

I need to compute the common part of 2 shapes.
I'm using a prism shape (created by face extrusion with BRepPrimAPI_MakePrism) and a second shape loaded from and IGES file.

So i have:
TopoDS_Shape prism (this is the "tool")
TopoDS_Shape igesShape (this is a large model, my "base" shape composed only by TopoDS_Face entities, it is not a closed shell)

I use the BRepAlgoApi_Common funcrion and i get a resulting shape that is not the common area of the 2 input. It is a weird fusion of the 2.

What can i do?
