I'm the author, so I will address everyone's comments in here:

> Why

To scratch an itch. I wouldn't have ever made this if /I/ had to make it. I wanted a way to express the primitive solids in a way that my autistic brain understands (through rigid object definitions in code). I have another neurodivergent trait called aphantasia which doesn't let me easily (at all really) conjure images in my mind, everything is described as text in my head... literally like reading a book, bringing up an "image" takes me multiple seconds while I read through all my brain comments about an image, especially if I'm supposed to focus on one feature. So I had an LLM build a tool for me (why it is called JermCAD and not something more professional sounding) that works how my brain does.

> How does it compare

100% doesn't. All of those tools are light years more advanced, and while I did try to use a CadQuery JS port, and another threejs CAD plugin, I couldn't get them to work, and I'm not a fan of python, so I stuck with what I knew font-end, web development.

> AI Slop

Yes. But again, this is a personal project that scratched an itch for me. It is a testament to how far you can get something in a few hours with an LLM, that would have taken months or years, but likely never would have happened, because who is going to invest months into redefining CAD to work the way that their specific neurodivergence works (Well maybe an autistic person hyperfixated on it, or me when I was 25 years younger).

This software as it is probably isn't useful to anyone except for myself. I originally shared it a few days ago to start a conversation, it got no traction. I am not saying that this or any vibe-coded, AI slop should ever be production software, but why not use it for a very specific implementation of something?

How does it compare to OpenSCAD, bitbybit, JSCAD, FreeCad, CadQuery, Curv, implicitCad, libfive, RepCAD, etc?

I mean it's nice that it exists, I guess, but there are already quite a few project (my list here isn't exhaustive) that seem (on the surface at least) equivalent beside the input format (YAML, but maybe some support that, I don't know).

So I don't want to imply that this has been vibe coded just to avoid searching what already exist, why they exist, why they don't support one specific feature... but still now that we are in this situation, namely 1 more item on the least, how can we compare it with the rest in order to know which one to use for our own needs?

>code-based CAD solution

Worth mentioning OpenSCAD & ImplicitCAD. There's also Antimony which has a graph-based modeling approach.

Very predictable amount of snark being aimed at this, but to me it’s incredible that something of this complexity is even possible with a few hours of effort. It is irrelevant in this moment whether this has bugs or is useful to others; what it signals is pretty significant. In a year this kind of effort will be able to yield something even better.

tfw faster to build cad than learn cad. great job, isn't this how earliest incarnation of cad use to work, i think they had stylus, human interface support fair early, but before that one would expect just imputing coordinates in punched tape or something equally tedious but obvious to some brains.

This is really cool! All the best with this

If it is browser based where's the browser link?? I wish there was a downvote button for submissions.

Instead of spending half a day learning CAD basic, let's rebuild the worst version full of bug! Yays!

Also, there is an easy to learn basic cad. It's called Tinkercad.
