Hi, 

I'm trying to convert a Delaunay_triangulation_3 to a simple
Triangulation_3, but i have failed, here is the way:

First, typedefs:
typedef CGAL::Exact_predicates_inexact_constructions_kernel       K;
typedef CGAL::Triangulation_vertex_base_with_info_3<vertexInfos, K>      
Vb;
typedef CGAL::Triangulation_hierarchy_vertex_base_3<Vb>             Vbn;
typedef CGAL::Triangulation_cell_base_with_info_3<cellInfos, K>     Cb;
typedef CGAL::Triangulation_data_structure_3<Vbn, Cb>               TDS;
typedef CGAL::Delaunay_triangulation_3<K, TDS,CGAL::Fast_location>   
Delaunay;

typedef CGAL::Triangulation_3<K,TDS> Triangulation;

then i insert some points into an object of Delaunay: mydelaunay

I create an object of Triangulation: mytriangulation.

finally, I want mytriangulation.tds()=mydelaunay.tds(), but I got error of
compilation. 

can not anyone help me. thanks in advance
