Hi GestaltDesign,
thanks for the info, and for the link to your thread :)!
I guess I'll just stick around with the Alpha 0.6 for this particular project, and hope that Ondra will be able to resolve the issue in future versions. Up till now neither do I process the STEP / IGES files myself, nor do i have any influence at what kind of data is being delivered, very unfortunate. But good to know the issue is known!
Thanks a lot again, and thank you Ondra for doing the incredible job out there :)
CheerZzz,
G.S.
