With the release of the RPi 4, it contains a spec that is capable of running a native version of Windows 10 yet to be tested.
But in thinking of this it would be good to see if an SD Card image with a build of Fusion 360 specifically built for the RPi 4 is released, the benefits of this its gives as the RPi 4 supports dual 4k output, USB3 and Gigabit Ethernet, it makes for the perfect Pocket Design computer.
So this would be good, and of course if this is built on a custom build of Raspbian designed to be resource efficient, it would make the perfect design workstation.
