For me it's a bit different - just installing things to get build123d to work is an insurmountable obstacle. Because I'm not a programmer it's rage-inducing. But I guess that's how this stuff goes 😉

If you want the best tutorials on FreeCAD, check out mangojelly on youtube. He has a current 1.0 beginner series that starts right from the very beginning. And he goes slow enough to easily follow along.

Ignore the huge number of workbenches. You can even go to the Settings and turn the ones you don't need off so you never see them again. You are only going to use 2 workbenches 90% of the time-- Part Design and Sketcher. And as you get more experience, you might add another couple of workbenches as you go. Most of the third party workbenches are specialty things. For example, I sometimes need to design and make gears or do small sheetmetal work. So I have the Gear and sheetmetal workbenchs installed. You probably would never need it.

Learning CAD, no matter what flavor, does require effort. It's as much about learning how to think as it is about learning how to do.

I find the opposite. There's so many videos on FreeCAD its wonderful. And if you're stuck, ive posted to the forums and within a week someone literally took my file and made a video showing how to do what I couldn't figure out.

Such a fantastic community.
