Hi Per,

Wow! That compiles! Now I’m confused. Where is tds() defined?

I had been using the Tds from the:

typedef CGAL::Triangulation_data_structure_3<Vb> Tds;

Also, I looked at the documentation and realized I could delete vertices, so 
I was doing:

for(size_t i = 0; i < 4; i++)
        {
          /// Remove all vertices in the invalid cell
          D3->remove(cit->vertex(i));
        }

Thank you for your answer, sorry about the further question!
