Hi Andre,

Did you ever figure this out?
I have a very similar issue..

It looks like the OFF_to_nef_3() function manually projects all polygons into 
a 2D plane, performs a constrained triangulation before constructing the Nef 
from the triangles. Since this functionality is not specific to OFF files, it 
would make sense to have a more robust builder which could construct Nef 
polyhedrons from polygon meshes, including Polyhedron_3.

Kind Regards,
