Don't bother with FreeCAD. You are not a hobbyist, capitalist society is already cruel enough without you shooting yourself in the foot with weaker software.
As an Electrical Engineer I use GStarCAD (AutoCAD clone), it runs well on Wine. There are a few pre-cracked versions on 1337, some of them do not work well. I run it on Bottles on Flatpak.
Could you be studying Mechanical Engineering perhaps? Just dual boot for that. You should give up any attempt at getting those programs to run on Linux. You could use a virtual machine but you'd need a powerful computer.
