I'm posting here this regression:
Even a simple Part container, with some simple objects inside, would be exported as an empty STEP file by the stable and the daily FreeCAD release...
I have reported this at mantis
The regression is based on the interaction of OCC7.2 code and the FC exporting routines ...
What I'm asking here is if we would need to:
1) step back stable release to OCC7.1 until we found a patch
2) offer a stable release with OCC7.1 (in 7z for win, appimage for linux and dmg for mac)
This is a very big issue on STEP interoperability since these great enhancements reached since Jul 11, 2017
I'm very sorry I didn't catch the issue before the stable came out, but I had very little time to test between release 13488 and 13509.
