Original Wing Geometry

original_sweep = wing.get_sweep()
wing.set_sweep(original_sweep) 

Altered geometry

Thanks @lattaud for the find. Originally posted in this discussion.

Could you please provide a MWE? I tried to reproduce this with a recent version of the main branch as well as the release 3.5.0rc1 and failed, see attached files.
