Hello,

Have you looked at the following example : 
https://doc.cgal.org/latest/Subdivision_method_3/Subdivision_method_3_2Customized_subdivision_8cpp-example.html 
? You can customize your Loop subdivision's mask, e.g. to have vertices 
not moving and new subdividing points being middle of existing edges, 
which is what you wish to have if I understand correctly.

Best,
Mael
