Hello,

you can adapt the hybrid domain example by replacing the 
CGAL::Polyhedral_mesh_domain by a 
CGAL::Polyhedral_mesh_domain_with_features_3.

Then you should be able to use detect_features().

If you knew the polylines a priori, and regarding the images you sent, I 
think the most adequate mesh domain would be the 
Polyhedral_complex_mesh_domain_3 [1]

Jane.
