CGAL users discussion list

All:

I've just downloaded CGAL and I am totally impressed
with the amount of functionality provided.

My interest is in doing some 3D Boolean operations
and the Nef3 Polyhedra look like it will be more than
adequate for my purposes.

I modified the Nef3 stack demo to write out .nef3
files and I was wondering if the file format is
documented anywhere?

If not, is there a code example that iterates over
all of the exterior facets and provide both the
exterior polygon boundary and the any internal
polygon hole boundaries?  (Please excuse my use
of terminology, I am an electrical engineer by
training, so I frequently use the incorrect words
when I am in the mathematics/geometry domain.)

Any help would be greatly appreciated.
