Hi Matthias,

you are probably using one of the projection traits like 
Triangulation_euclidean_traits_xy_3, right?

p_c from your example below should be of type Traits::Point_2
The point type of the projection traits class is Point_3. You should try 
something like

Traits::Point_2 p_c(2.0,3.2,42);
Face_handle fh = Delaunay.locate(p_c);

where you put 42 as the coordinate that is discarded by your traits.

hope that helps

Manuel
