A full-featured 2D + 3D CAD application built in Rust with GPU-accelerated rendering. Native DWG & DXF read and write, paper space, ACIS solids, dimensions, layouts. An open source community project by Hakan Seven, recognized and promoted by the OpenAEC Foundation.

AI slop? You can't build stuff like this by hand in a few months.

what solver does it use?

claude is a co-auther, so yeah.

oh also the openaec foundation endorsement means literally nothing, they didn't exist three months ago, their website is all vibecoded, and they linkjacked the name of an existing organisation with the same name incorporated in japan.

I hate AI slop as much as the next guy... but what if this is useful.. been looking for CAD software on Linux for ages -.-

been looking for CAD software on Linux for ages

FreeCAD has become pretty good lately. If you have tested it before v1.1 (March 2026) you should certainly give it a go again.

If you're fine with programming your CAD instead of visually composing it, OpenSCAD is fine as well.

If the latest builds aren't able to meet your needs I've been thinking about trying blender+ a parametric cad plugin. There are some limitations, but it might be able to do what I need without having a painful to learn UX

But people have been telling me freecads latest releases (maybe the nightlies?) Have gotten much better so I'll probably give it another shot

1.1 and forward is night and day, yeah.

Solvespace has been working for me, but I don't do complicated cad. I recommend getting familiar with solvespace if you want to try the cadsketcher blender plugin since it is basically solvespace glued into blender.

I do like openscad but I must be using it wrong because it slows to a crawl when trying to array my models

On an unrelated note, if someone tries to rugpull a foss license, but Claude is listed as a committer, can the license be changed? I thought licensing ai code was basically a no-go since copyright has been scrapped for ai output???? I'm sure that won't last.

I love the simplicity of SolveSpace but I wish they'd have a loft or sweep feature and it would support free form modelling in some way. Then it would be perfect for me.

Maybe you can reduce the $fn parameter while you arrange your models and increase it once you're done? That's the most common thing I encountered.

There are some config flags you can set which might improve render times, maybe play around a little.

All in all it will take a long time to create meshes because most of the compute is done on CPU. For me it's very fast once it's done rendering, so I try not to render too often.

Slop or...? Edit: slop.

Not free, but Brics CAD oficially supports a few distros.

Whatever Claude put in

Does it matter if its made by AI if it works well? I see they got some other fun apps too that might be useful and where no human made alternative for exists

As far as I know the ruling specifically applies to cases where there there is no human involvement whatsoever, since copyright can only be granted to human authored works. If something has an element of human involvement it may be copyrightable even if generative tools were used in its creation.

It's not some sort of "anti-copyleft" deal where a single generated commit somehow nullifies the copyright of the human-authored parts. It's kind of a trend among slop-detractors to act like this is the case (that a single piece of generated text somehow turns the entire project into slop) but there's no legal basis for that I think.
