Hi Monique,

yes I have had a look.

But it seemed to work with the 3d Delaunay Triangulation and so it
didn`t matter.

But now I found this situation.

So plz tell me if I`m wrong:

Because I don`t know which wall is a vertical or a horizontal wall and
so on I would use:

CGAL::Triangulation_euclidean_traits_xy_3<K>
CGAL::Triangulation_euclidean_traits_xz_3<K>
and CGAL::Triangulation_euclidean_traits_yz_3<K>

for every of my fassades and then merge the results of all of them?

Could this work? Or is there a more simple way to do this?

Two other questions:
How do I get the points of an edge of a 2d Delaunay Triangulation:

for(Delaunay::Finite_edges_iterator ie = T.finite_edges_begin(); ie !=
T.finite_edges_end(); ie++)
{
    ie->first->vertex(ie->second)->point() // doesn`t work so far
    ie->first->vertex(ie->third)->point()
}

What`s wrong on this:
for(Delaunay::Finite_faces_iterator it = T.finite_faces_begin(); it !=
T.finite_faces_end(); it++)
{
                Triangle_3 delaunayTriangle = T.triangle(*it);  // error
}
