Hi Monique,

how can avoid a crash? Is it enough to check for "is_valid()"?

I read the manual and solved the problem with the edges and the points.

But I don`t understand how I get the 3 Points of a face with the help
of  the following loop?

for(Delaunay::Finite_faces_iterator it = T.finite_faces_begin(); it !=
T.finite_faces_end(); it++)
{
}

I thought about:
(*it).vertex(1)->point()
(*it).vertex(2)->point()
(*it).vertex(3)->point()

Is that right?

Best,
Dennis
