Hi Kamal

I am not sure to understand your problem
but still I make an attempt of solution :

you may insert whatever points you want (surface points in particular)
in the triangulation,
using
c3t3.triangulatiun().insert() before launching the meshing process.
These points will be preserved in the final mesh
if you next build the mesh using refine_mesh()

Hi Laurent,
I am looking for an example using the following function,
But before I want to know if this preserves the surface connectivity as well?

c3t3.insert_surface_points(...))

I tried also to add a contour (as a feature) from the respective surface using:

 domain.add_features(polylines.begin(), polylines.end());

this works perfectly but when I added all edges from the surface, I was not successful.

Is there any example for inserting surface points (with connectivity) 
into a volumetric mesh?

Please be more explicit. What do you call a volumetric mesh? The 'c3t3' 
created by the CGAL 3D mesh generator?


What you want is probably quite difficult to implement without knowing a lot of the internal of the CGAL 3D mesh generator.
