Yeah, I see Build123D being referenced a lot here. I'll give it a try, though I suspect I'll probably stick with Bowler Studio because I actually use the physics and robo simulation stuff a lot.
Bowler Studio was entirely new to me, so thanks for mentioning it.
One random mention: Nick Lockwood's ShapeScript, which is another code-CAD thing based around a mesh CSG environment (and pretty unusually runs on iOS)
Bowler Studio was sort of revelatory for me, because it gave me the ability to model a functional part and immediately test it. The physics engine obviously isn't going to be the most accurate of all time, but for a lot stuff that hobbyists do it can be useful, and being able to play with servos and motors really does open a lot of possibilities to avoid wasting time and prints.
I've actually played with ShapeScript but I admit that I didn't do anything terribly crazy with it.
Yeah I've only dabbled with it myself. Again it was part of this process of me orienting myself towards "thinking in 3D" and I'm really grateful to much more 3D-literate developers than me that we have so many choices.
This is a browser-based JS CAD thing built around an Emscripten cross-compilation of OpenCascade -- the fact that it works at all was revelatory to me about the capability of Emscripten, which had passed me by a little.
