Hi  Sebastien,

Thank you for your response. In that case, can I check placement or cost before removing? Because after sequential edge remove I see that the edges look weird.  How to remove edges in this case organized way?

Maybe can directly call:

CGAL::Euler::collapse_edge()

if the edge satisfy the link condition

CGAL::Euler::does_satisfy_link_condition()
