I use F360. Partly because it’s popular with the Astromech Builders Club so there’s lots of things available in .f3d format, but it also was an interface I could actually understand. I’ve tried various “modeling” programs in the past, and they never really made sense to me, but F360 does.
Maker’s Muse having a lot of videos on it helped too - I was already watching his videos so the cognitive cost of seeking out and trying to understand a tutorial was a lot lower. Searching YouTube for a tutorial isn’t as straightforward as it sounds; there’s an effort and cost involved in figuring out how to understand what the video is telling you.
@VagabondElf - I agree, Fusion really does make sense. It is definitely my preferred CAD program. I enjoy using it enough that I finally bought a license for it even though I still only use it for hobby purposes.
I have also started getting into Rhino a bit with the intention of learning Grasshopper. For work I use Cadwork but a few people in the office use Rhino for certain projects.
Blender is also on my list to learn in the hopefully near future.
So much to learn, so little time.
