Hi everyone,
I have a CDT with info base for every triangle, which is initially
partitioned in sub-areas, in a manner that a collection of adjacent
triangles have a specific ID attribute.
How can I create a new CDT with those triangles, refining the sub-CDT with
different constrain criteria?
 
I've tried copying the CDT and deleting the triangles not having the
specific ID, with no luck. 
(By copying the CDT and then either: 1.
//cdt_copy.delete_face(faces_iterator) or
2.faces_iterator->set_marked(false);)

The problem is that I cannot iterate through all the border triangles and
taking the edges since the iteration is not linear and I wouldn't also know
the orientation, in order to create the constrains for the new CDT.

Thanks a lot,
Fotis
