My high school STEM classes taught us how to use Autodesk Inventor and I can use it very well now but it’s hard to pick up another CAD software without it feeling weird.
I'd recommend looking into the history of it a little. it's crazy how committed this guy was to the idea of blender and more importantly his principles.
in the last few years blender went from being a joke to not only formidable competition but possibly the best software for a lot of use cases. funnily enough blender3d is probably the best 2d animation tool out there.
I also remember blender was considered a hobbyist tool and in last couple of years it has been used more and more for hardcore professional stuff (note that I'm not in the field to know the specifics, might be for much longer).
You can get Solidworks for about $50/year for personal use. That’s cheaper than many entertainment streaming services. It’s not the full suite, but IMO it’s enough to be a really good deal for the features you do get.
Autodesk is evil. They buy out all the competition, kill any perpetual licensing, increase the prices and then kill the project when all the value is extracted.
