Hi all,

It seems that the CGAL Triangulation_3 does not support holes. When I build 
such a triangulation by manipulation the data_structure "by hand", then 
the validity check on the data structure fails with "Euler relation 
unsatisfied". I guess that could be expected since the manual mentions how 
the triangulation is actually a covering of the 4D sphere.

Can anyone comment on the problems of using the CGAL Triangulation for 
genus > 0 objects? It is at least possible to traverse the object. Could I 
disable the check for conformity to the Euler relation and have something 
workable, or would I be bound to run into troubles along the road?

If so, are there plans to support such triangulations in the future?
