what if you write
typedef CGAL::Triangulation_face_base_2<Et> Fb;
instead of using K as template parameter there?


Face? That I haven't tried, since I thought it was the vertices which had to contain the z info.

It looked strange to me not to use the same traits for both vertex and face. As I said, it was just a try...

Anyway, I get the same errors I did before:

.../CGAL-3.3.1/include/CGAL/Triangulation_hierarchy_2.h:471: error: no type named ‘Compare_distance_2’ in ‘class Et’

It seems the "Et" does not provide a valid geometrical kernel for the hierarchycal triangulation (even if it does for the regular trinagulation).

Seems so, but I don't know this traits well enough to confirm firmly.
Note that you had not said anything about the error message in your first e-mail. The precision you just sent should now help somebody to give you the correct answer.
