In the past I used CAD 95% of the time in the form of Solidworks, so I had to use windows. The other 5% of the time I used excel, so i probably could have dual booted, but I never bothered. Fortunately (kinda) my current job uses it a lot less, so I main Linux and for small prototypes I use FreeCAD on Linux and dual boot windows for the bigger projects that demand the speed in Solidworks
