Fusion is very easy to learn. If you can use tickercad.

Just draw sketches, learn to extrude, push pull, and it all depends on how good you are at sketching in 2d, setting up constraints, workflow is simple and it works most of the times but when it doesn't work, it's pain.

I am pretty sure fusions workflow sucks but I can't put my finger on why. I am still waiting for a better product which is also free and opensource.

Maybe llm vibe coding will unlock this finally. Where bunch of people come together to take up parameterized 3dmodeling.
