Hi Nick, I also did a tune-up for mirror so that with non-solid surfaces, the surface normal direction will stay consistent with the original when mirroring, instead of the normals getting flipped.

Kind of an overhaul of normals handling for non-solids in general. I think it should solve many of these problems but there are a fair number of changes so please be on the lookout for any bugs in this area for the next beta.

Thanks Michael, now I won't have to worry so much about only exporting solids.

Is surface assignments going to be in the next Beta?

Well, it can still be better to export solids. Even with these changes, MoI still does not know which direction should be the "outside" if you create an open surface initially.

However, there will now be more consistency, the normals of an open surface will now not flip when doing mirroring or when saving to .3dm, and I've also done some work to make the results consistent when you do stuff like cut something up into pieces.

However, none of this "maintain consistent direction" work will help in the case where the normal direction on an open surface is not initially going in the direction that you want. I do expect to have a Flip command at some point to let you see and change this though.

But keeping things consistent through operations and saving is a good step forward at least. It's one necessary part of the whole thing.

I hope so, but I still have a fair amount of work to do to finish it up though. I've been kind of side tracked for a bit with some other work to make the export meshing multi-core enabled to speed it up and make it not freeze the UI while it is calculating.

Sounds great all around Michael - thanks for your hard work!
