That is good news! Thank you.

You need a other version of OCCT. In OCCT7.5.0 there is a step issue. On OCCT7.5.3 it will probably work. It works here in OCCT7.6.0 flawless. Greetings user1234 I see. Good to know it works with next OCCT version. Updating OCCT will require to recompile whole FreeCAD from sources, correct? As usua...
