Hi Michael,

Sorry for my late reply ! You're programming too fast. Users can not follow you anymore, hehe ! ;-)
Here's a Zip file containing
- Two screenshots showing the mesh object with default mesh resolution and lowest mesh resolution.
- The 3dm file (object was created with 4 curves and closed loft command)
- The low resolution .obj file

As you mentioned, it is always possible to cut the object in two pieces and create a symmetry object in a poly modeler. It is just an extra step that I'd like to avoid.

Brand new beta looks great !

Edit : Sorry, I just noticed that the circles to highlight the "problem" area on "Screenshot_2.jpg" are not exactly at the right place. It can be a bit confusing...
