I am unfamiliar with refind, but from my experience with systemd & grub dual boot, if you do not change your boot order in bios, there is a high chance that the windows boot manager will brick your Linux one, even across drives. My advice for dual booting is to ditch the convenience of using one boot manager. But once again, this may not be an issue you have.
I would recommend making your own post to get more help. On the cad side of things the alternatives are free cad, on shape, or blender; I don’t have that much experience with them, but just based on my fusion experience, I would assume they can all do the same things, just in completely different ways since fusion had it’s own special way for literally everything.
