Get the CAD/VORON2_v2.4_Assembly.step.zip from https://github.com/VoronDesign/Voron-2 and try to import it to FreeCAD ran using `guix shell freecad -- FreeCAD` 2. Get the CAD/VORON2_v2.4_Assembly.step.zip from https://github.com/VoronDesign/Voron-2, extract it so that you have the unzipped STEP file and try to import it to FreeCAD ran using `guix shell freecad -- FreeCAD` Expect failure above for both cases Expected: Just work(TM) Hypothesis: Probably mising some runtime library, tried to use `guix shell qtsvg python-pyside-2 freecad -- FreeCAD` without success -- Jacob Hrbek, In support of ukraine sovereignty #supportUkraine
