Hi Ralf,
thank you for this hint - never heard of CAD-Exchanger before. I will try it out now.
I just imported the Step into KeyShot 2 - it did not crash so Step import seems to be more robust in KeyShot 2. But in the KeyShot 2 import some parts are missing (i.e. the D-SUB9 connectors)
Thany you and kind regards,
Uwe
