A few days away and I miss a thread I might have actually been useful on ;)

Anyway I would also go for a dual boot setup - if any software is going to misbehave in a VM, CAD is usually somewhere near the top of the list.

Given the features of Fusion 360, I would expect you will find you'll use your old software less and less (unless you have a Solidworks/i-Machining combo). The only thing I am using Cut2D for these days is converting pdf plans into DXF, which I then import into Fusion for modelling and CAM. I haven't touched Cut3D or DeskProto since using Fusion, the latter of which I thought was a very good CAM package.

BTW - you might be interested in this video that showed up in my Youtube subs today, which I thought was a good intro/quick start for Fusion as well as helping users coming from AutoCAD: https://www.youtube.com/watch?v=s_Th0BDUUF4
