Hi,
thank you for your reply!

The kernel choice was one of my guesses. I had found a segmentation fault
using a CGAL::Simple_cartesian<double> (as in AABB examples) and a lot of
errors in make_mesh/refine_mesh when choosing a
CGAL::Exact_predicates_exact_constructions_kernel (or
Exact_predicates_exact_constructions_kernel_with_sqrt).

Thanks again


You need a kernel with exact constructions only for computing the intersection points.

You probably need to use CGAL::Cartesian_converter
