I don't use it, but I am told that a big chunk of the features are being removed from the "free" version of Fusion 360. Key among them are an active model limit of 10 models OR drawings, a one sheet limit on drawings, print only output of drawings, and pulling of ALL the useful file format outputs, such as STEP, IGES, etc. NO CAM output at all. There are other things that I do not understand the significance of, because I have never used Fusion at all. In other words, Fusion 360 free will be essentially out of the picture as a competitor to Alibre or Atom, with the first stages (quite a lot of the above) happening as of Oct 1 2020. The description given to me was that it is being "Nerfed", the new version relates to the prior version as a nerf ball relates to a standard US baseball..... does not much useful. While beyond annoying to the Fusion users, it is a plus for Alibre, most likely. I expect many saw this coming, but many others likely did not. With the October deadline affecting the allowed file export formats, a lot of folks will probably need to spend a lot of time exporting files pretty soon.
