Got this email from Autodesk that Fusion is increasing their annual price by a huge amount. I subbed for 1 year a couple years ago for I think $380. Then I was able to get an educational sub after that. Fusion is still the cheapest CAD software out there, not including the free stuff like FreeCAD, but still, this price increase is massive.
It should be noted that it’s still free to use for personal use minus the extra features.
So most of the big packages have a cheap or free tier for hobbyist/maker use, and I think they all do for educational use. The rub with most of these is that they are either not for commercial use (OnShape, Solid Edge CE), or they have “gotcha” thresholds ($1000 revenue for F360, $2000 profit for Solidworks).
Now if you wanted to go completely free-as-in-beer and still retain full commercial rights, you really have to go open source. Then there’s also DesignSpark Mechanical, which is Windows only and not truly parametric, but is much more advanced than something like TinkerCad. They’ve got their own issues with feature erosion in the free tier, but because the company’s main business is selling components, they haven’t removed commercial use from it yet.
