Hi Bernard,

> Is it related to the "problem" I had with mesh symmetry ?

Yup! A closed loft should behave better now and not have the slight shift in it that caused your previous symmetry problem.

The quad meshing improvement also helps with symmetry - this enables an n-gon that looks exactly like a single column of quads to be split into quads instead of triangulated (in quads & triangles export mode). This also improves symmetry for that shape you previously posted.
