Hello dimitris!

You should look into CGAL examples.
After You have installed CGAL You can find in installed folder of CGAL the
folder /examples/Nef_3
in this folder You can look e.g into the files
interface_polyhedron.cpp and nef_3_construction.cpp

You can do e.g. following operations:

Creation of Nef_polyhedron, e.g.:
  Nef_polyhedron N0;
  Nef_polyhedron N1( Nef_polyhedron::EMPTY);
  Nef_polyhedron N2( Nef_polyhedron::COMPLETE);
  Nef_polyhedron N3( Plane_3( 1, 2, 5,-1));
  Nef_polyhedron N4( Plane_3( 1, 2, 5,-1), Nef_polyhedron::INCLUDED);
  Nef_polyhedron N5( Plane_3( 1, 2, 5,-1), Nef_polyhedron::EXCLUDED);

You can make * (intersection), + (union), - (difference), ^ (symmetric
difference) operations on Nef_polyhedrons:
     N6 += N3;
     N0 = N6 * N3;

Look into documentation
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Nef_3_ref/Class_Nef_polyhedron_3.html#Cross_link_anchor_1174

Converting polyhedron into nef_polyhedron:

  Polyhedron P;
...
  if(P.is_closed()) {
    Nef_polyhedron N6(P);
  }

Converting nef_polyhedron into polyhedron:

  if(N6.is_simple()) {
    N6.convert_to_polyhedron(P);
  }

I wish You much success!

Best regards
