Hi Michael T - do you still have the previous Dec-19 v2 beta installed?

If so could you please give it a try with that one and see if you get different results with the same files?

I did do an update of the STEP/IGES/SAT import/export libraries for this last Feb-21 beta, so it would be good to know if it is something related to the updated library or not.

If you do not have the Dec-19 beta still installed, you can e-mail me at moi@moi3d.com and I can get it sent to you.

- Michael
