After an hiatus of over four years, CAD software is back in the KaOS repositories.
Freecad was still Qt4 based in 2017 (as were many of the needed depends), and had to be removed with the Qt4 removal.
Now PySide2, Shiboken, Pyside2-tools, Coin, Soqt, VTK, Med, Opencascade & FreeCAD are solidly ready for Qt5 & Pyhton3, so the whole stack is added again.
This has always been a very labor intensive stack, and takes a lot of time and effort to properly maintain, but having absolute nothing to offer for Computer Aided Design Software is not desirable.
Please report here if you find issues with this stack, or if you find something missing (Matplotlib is missing in FreeCAD, build with it, but the FreeCAD buildsys does not find it yet).
