I spent 2 days crash coursing freeCAD (this is with a general understanding of the theory of 3D design already) to try and make an adapter plate for my car. A plate with 6 holes in precise spots and tapped. It was absolutely brutal and after the first 3D print trial had the a couple holes misaligned, I trashed freecad got the free fusion360.
No shit, in 20 minutes I had made the exact part I needed. The program actually worked the way you would expect. I didn't even need a tutorial it was so intuitive. Even if I hadn't spent the previous 2 days getting bent by freecad, I'm pretty sure it would have taken me only an hour max with a blank slate mind in fusion.
Now I'm getting angry writing this. If the FreeCAD guys see this, thanks for the hard work, but understand your minds must work completely differently than even the average engineers.
