I think I was able to trace back to the source of the problem.
If I use the output_surface_facets_to_off function, I can see that some facets are not considered on the surface, and thus are not output in the final model. I assume that the dangling vertices belong to those facets.
Is there a reason why this would be the case after a make_surface_mesh() operation?

Hello Sebastien,
Here is how dangling vertices are detected:
We convert the mesh to a polyhedron, using:
CGAL::output_surface_facets_to_polyhedron
then loop through the vertices with
for( VCI vi = polyhedron.vertices_begin(); vi != polyhedron.vertices_end(); ++vi)
{...}
then the faces with
for( FCI fi = polyhedron.facets_begin(); fi != polyhedron.facets_end(); ++fi)
{...}
as part of the conversion to our own mesh class.
Any vertices not part of a face are considered "dangling".
Could you indicate how you detect that there are dangling vertices?
Sebastien.
