Polylines to protect?

[d-v-t]

As I was using surface to volume mesh, I discovered that the algorithm currently doesn't do a very good job at conserving straight lines. I looked in the code to see if there's any compatibility CGAL's polylines to protect, but couldn't find anything. Is there support for this? Is this in progress?

This really happens? Seeing is believing, please attach a surface mesh so I can try it out for myself. :smile_cat: I can try and fix it then.

These are a. the surface mesh of a simple hexagonal extrusion and b. the results of the surface to volume mesh. I consider the .vtk file to have reasonable mesh sizing but somewhat poor edge node accuracy. I'd attach these in a post on the error report, but Github doesn't like the filetypes.

You can zip the file and attach it.

hex_test.zip Slipped my mind

Did somebody work on this? A simple solution is to add a call to detect_features in generate_from_off.cpp for single body cases.
