Hello,

I'm trying to implement a limited 3D arrangement with multiple Nef_polyhedron_3.

Before approaching it, I'm struggling with the concept of "shells", specifically on how to iterate on shells of a volume.

From what I understand, iterating using shells_begin() would give me each time a shell, which is, from the documentation:

A Shell_entry_iterator is assignable to SFace_handle.

But, I'm not dealing with SFaces at all - I want the regular Halffaces.

Is there a better example for a case like mine or an explanation? I would really appreciate it.

Thanks,

Kobi
