Hi!
I have done optimization for my model, got the results and have created geometry based on the results using OSSmooth. Model is not very big - just 2 blocks 900x300 mm.
But when i press safe&exit and the exporting progress reaches 100% (as shown below), hypermesh hangs in this state (also showing Not Responding) for hours and nothing happens, no STEP file is created.What could be the problem and how I could overcome it?

Thank You!
