Hello,

Suppose I have a closed Nef_polyhedron_3 N, and I construct a plane with 
Nef_polyhedron_3 in this manner

Nef_polyhedron_3 N;     // closed

// now constructing a plane Nef
Plane_3 pl(1, 1, 1, 0);
Nef_polyhedron_3 N_plane(Nef_polyhedron_3(pl) * !Nef_polyhedron_3(pl, 
Nef_polyhedron::EXCLUDED));

// Now I intersect these 2 Nef:

Nef_polyhedron_3 N_res = N * N_plane;

Now N_res is actually a Nef_polyhedron_2, but is there a way to convert it 
into a Nef_polyhedron_2
and then explore it accordingly?

Thanks in advance.
Max
