Dear Tina,

if i understood well, you tried to use the CGAL surface mesher (e.g. 
CGAL::make_surface_mesh).
If you use the oracle that intersects a polyhedron, the surface can be 
"open".
You should use the Manifold_with_boundary_tag (or the Non_manifold_tag), 
rather than the Manifold_tag
that tends to close the surface quote: "but after triangulation I will 
get a close object which all of the borders are connected".

Here is a link to the documentation : 
http://www.cgal.org/Manual/last/doc_html/cgal_manual/Surface_mesher/Chapter_main.html

Yours,
Nad.
