I saw the example using Delaunay Triangulation 2.5D and everything works fine.

Is it possible to use Conforming Delaunay Triangulation with CGAL::Projection_traits_xy_3?

I'm trying using this setup:

typedef CGAL::Exact_predicates_inexact_constructions_kernel K;

typedef CGAL::Projection_traits_xy_3<K> Gt;

typedef CGAL::Triangulation_vertex_base_with_info_2<std::string, Gt> Vb;

typedef CGAL::Constrained_triangulation_face_base_2<Gt> Fb;

typedef CGAL::Triangulation_data_structure_2<Vb, Fb> TDS;

typedef CGAL::Exact_predicates_tag Itag;

typedef CGAL::Constrained_Delaunay_triangulation_2<K, TDS, Itag> CDT;

typedef K::Point_3 Point_CDT;

I can't insert a Point_3 on a CDT. I tried using CGAL::No_intersection_tag to avoid create new points with no success.

Is there a way to use Conforming Delaunay Triangulation 2.5D?
