I'll have to see what I can do about assembling the IGES file. But even at best, it's still (obviously) a much bigger pain to work with - as compared to STEP, because the lack of naming structure and the sheer number of pieces to re-join.

In the meanwhile, I was at least able to get the Alias designer to send me a comprehensive screen grab of the potential export settings for STEP files, from Alias. Do any of these stand out as critical in regards to how MOI might best prefer?

Thanks!
