These code base cad systems are pretty great. But all of them are imperative languages and as such can only solve imperative constraints. Including declarative constraints would be very welcome. I mean, sure, Theoretically we could enter the turing tarpit and build our own constraint solver, but it would be nice to see one included as a standard library.

I am trying to think of an example, declarative constraints are usually the domain of a graphical cad system(like solvespace). but I suspect it would look like a set of relationships you can enter in any order and it solves for the missing one. so... prolog? has there ever been a cad system in prolog?

I'll throw my hat in on the feedback... looks great!

My pet use case is: "My naive approach as a programmer would be: `pen := new Pen(q,r,s,t); box := new Box( pen.L, pen.W, pen.H )`" along with being able to sometimes work with the whole pen, and sometimes touch the pen vs. the cap separately.

Since it's all javascript, it seems like there's a chance that this use case would work (ie: `p = Pen(...).render().getWidth()`)? Additionally, your intermediate step screenshots really makes it seem like a SketchUp-ish GUI would be perfect! Obviously a ton of work, but SketchUp's "grab face + extrude / push", but if it were "sticky" to the underlying parametric components seems like it'd be an awesome combo... something like group/components, but backed by code instead of GUI-only (or GUI-centric) editing.

This looks incredible, great job!

I've been revisiting OpenSCAD recently but find it very frustrating. I just got started with build123d which is great but I'll definitely be trying this. The workflow is exactly what I'm looking for.

I'll drop an issue if I have feedback. Are you open to PRs?

The thing that made Flash magical was that it had the approachability of a design tool (and it really did have some of the best design tools ever), with the extensibility of a scripting language. You could start by drawing on a canvas and grow into programmatically generating designs.

This looks like it could do the same thing for constraint modeling. That's awesome!

I don't know much about CAD but it is surprising to me this hasn't existed before seems so natural. great work

Impressive to see parametric CAD running in the browser. Curious how you handle precision with floating point — that's usually the first wall you hit with geometry in JS. Does it support STEP or DXF export?

Nice work and kudos for programming it by hand! Starred the project and plan to try it out soonish.

Why use this rather than Maker.js?

Really interesting! Is there a list of all supported CAD operations? Can I “revolve” 2D sketches? Can I make assemblies?

I've been working on this exact idea! But it's late, will remember to come back and check this out to compare notes.

This looks great. I just started trying to generate some models using golang and the ecosystem doesn't seem great. Will check this out, might work out better.

This looks awesome.

What geometry kernel is it using?

Which operations are supported? (Booleans? ...)

Where's the API link?

...finally, was this vibe-coded?

Inquiring minds want to know!
