Having to shut my main work computer down and swap out the hard drive to Windows just for one program really sucks though, so I will continue to use Onshape for CAD work, and Estlcam (via Wine) for simple 2d paths. I also find the forced use of the middle mouse button in F360 to be infuriating, none of the other input options are better and you can't just map the buttons to your liking. I tried Autohotkeys to remap mouse buttons which does work but every few minutes all button input freezes for up to five minutes, which is even worse. Fortunately time spent doing CAM work is a smaller percentage of overall design than doing CAD work, so swapping out the hard drive when I need CAM is a workable arrangement for now. If I'm feeling rich some day it might be worth buying a whole new computer just to have F360 ready to use at any time without disrupting day-job work. Yes, I
