Dear Peter

I have bought a book in order to understand NEF polyhedron basics :-)
As you suggests, I think I'll start with the PLY format instead of the
STL: there is a library at
http://www.tecgraf.puc-rio.br/~diego/professional/rply/

If you can provide me an example for a simple (code made, with few
facets) polyhedron it'll be very usefull.

   thanks a lot

                    Andy
