Hi Joe,

I had the same problem a few months ago, did you try triangulating your polyhedrons before converting them to nef ? This solved it for me :)

Good luck,
Laure

I still could not find solution. Any other requirements on polyhedron besides "closed" and "valid" to make sure the intersection go through?

Hi All,

Intersection of Nef_polyhedron_3 failed When I tried to compute
the intersection of two polyhedra (see attached files). I am using
Exact_predicates_exact_constructions_kernel. Both of the polyhedra
are closed and valid and have been converted to Nef_polyhedron_3
successfully. It failed when executing the intersection of
converted Nef_polyhedron_3. The version of CGAL is 3.4 with Visual
Studio 2008 (SP1) and Win XP Professional.

Anyone can help with this?

Thanks.
Joe
