Hi Padraig,

Thanks for your reply.
It actually pointed me towards the right solution. Here is what I do now:

for (Tr::All_facets_iterator it=t.all_facets_begin(); it !=
t.all_facets_end(); ++it) // loop through facets
{
  Tr::Facet f(*it);
  C3t3::Surface_patch_index sp = c3t3.surface_patch_index(f);

// now sp.first/second contain information to which domains the facets
belongs (on both sides)

// now get the vertices of the facet and add the triangle to the belonging
cells
...
}

This generally works well, however occasionally I get malformed regions,
where there is 1 or 2 triangles too many, so that the domain cant be closed
proplerly. Another problem is that the orientation of the triangles seems to
be random. is there a way to get oriented tris from CGAL?
And finally I haven't solved the first problem (of the inital posting) yet,
I can only open 3d data from files.

Thanks a lot.
