Dear All,

I am working on the inverted problem of Thiago (I am interested what is left 
after to polyhedrons are subtracted form each other)  and have the same 
issues as Thiago and Taus. Some clarification would be really great.

Please keep posting about any insights you may get, I will do the same as I 
go along.

Best wishes,
Merlin :)

Subject: Re: [cgal-discuss] Nef_polyhedron and 
Exact_predicates_inexact_constructions_kernel

I have run into the same problem. I have a hard time know what kernel are 
usable for what. Even though the exact and inexact construction kernel models 
the same concepts, they seem to be different in some ways. I have found that 
the Exact_predicates_exact_construction_kernel
works for use with with Nef_polyhedra_3.
