I’m using plasma on Gentoo, Arch and Ubuntu with barely any issues, on desktops, work laptop and older Thinkpad, Nvidia and AMD. Since 6.1+ and on wayland even the multi-monitor stuff works as expected.
The only thing I’m still missing on 6.x and wayland is a replacement for khotkey.
If you have zero experience with CAD, but some experience with programming languages or things like LaTeX, JSON, XML, HTML, etc., I’d suggest giving OpenSCAD a try. While it is definitely for more advanced users, it managed to instantly click with me, in contrast to FreeCAD and others I just couldn’t get into (or rather back into, since my AutoCAD lessons back in school >20 years ago). That it allowed me to work work on CAD drawings in Emacs helped too…
