Gemini 3.1 whilst not the best agentic coding model, has extremely strong vision (which makes it reason spatially very well).

Fable 5 was top for a brief moment, whilst it was around!

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Thursday June 18, 2026 @01:15PM (#48588492)
yup!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Thursday June 18, 2026 @01:15PM (#48588490)
Could I see what you tried to generate?
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Thursday June 18, 2026 @01:15PM (#48588487)
To be completely honest CADAM is not at all a revenue driver for us. The majority of our customers are on our flagship app: https://adam.new/ which uses OpenCascade and allows you to connect to your CAD, PLM & PDM tools.

We built CADAM largely to give back to community and support a tool for hobbyists and individuals.

Thank you for giving it a shot!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @08:24PM (#48578896)
CADAM is pretty good at building Gridfinity
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @08:08PM (#48578781)
nice!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @07:02PM (#48578224)
yep
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @06:15PM (#48577708)
Sweet!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @06:15PM (#48577703)
Most of our users on CADAM are makers/tinkerers. Their #1 usecase is to generate a printable stl file for which openSCAD is ideal (LLMs are very good at generating it)

For professional workflows you can use https://adam.new/ which can work natively in your CAD software and generate .STEP via build123d

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @05:58PM (#48577502)
You can use https://adam.new/ if you want to connect to your CAD applications or generate real breps
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @05:54PM (#48577442)
tackling all that in: https://adam.new/

don't you worry ;)

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @05:29PM (#48577181)
This is so the .scad file stays the canonical state. With -D, the rendered geometry diverges from what the file says.
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @05:00PM (#48576830)
I agree openSCAD isn't anywhere near powerful enough for professional workflows. Hence why I framed this as AI TinkerCAD.

However, you can drive any professional CAD software though code. As we drive Autodesk Fusion via python through agents.

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @04:41PM (#48576573)
The same principles of an agent writing cad as code and then visualing inspecting the output in a loop runs through all our products. Whilst CADAM uses OpenSCAD, Fusion uses Python, Onshape use FeatureScript etc..

The majority of our enterprise traction is on our flagship product: https://adam.new/

Here you can connect to your engineering software and use AI to generate:

- CAD - Renderings - Slides for design review - BOM

and much more!

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @04:09PM (#48576133)
Honestly I would've liked to MIT. It's mainly that the openscad wasm we use is GPL
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @04:08PM (#48576128)
Yes it can! You can even use mesh mode which is very strong for this!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @04:01PM (#48576019)
I strongly believe that by scaling up LLMs we will get there. I write about this here in more detail: https://adam.new/blog/bitter-lesson-ai-cad
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @03:42PM (#48575789)
yes i agree, this would probably fix it
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @03:42PM (#48575783)
curious how this compares to on baseline: https://adam.new/

let me know!

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @03:37PM (#48575691)
Yes I intentionally called this AI TinkerCAD
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @03:03PM (#48575163)
I largely agree with you. It's case by case and the ideal ux imho is to have both.
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @03:02PM (#48575140)
generally professionals our flagship app at https://adam.new/

hobbyists and makers use CADAM

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @02:45PM (#48574860)
Fable is considerably better from my experience: https://x.com/LLMJunky/status/2065229625702109340?s=20

Fingers crossed it comes back!

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @02:39PM (#48574760)
you can upload an image or a sketch! we actually have drawing suppor in our extensions, but we've found our users use it far less than we expected!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @02:22PM (#48574506)
Thanks!!
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @02:22PM (#48574497)
I write about this in detail here: https://adam.new/blog/bitter-lesson-ai-cad

This is improving greatly in recent model releases

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @02:13PM (#48574361)
That's more of an example to address the point. We've find our users often use this feature in our onshape/fusion extensions in complex assemblies. Being able to select faces and edges as context in addition to prompts can be quite a powerful interface in more complex projects where users need to adjust tolerances or edit multiple objects to prevent interference
Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @01:30PM (#48573690)
Yes and we have a number of mechanical engineers using our extensions! AI in CAD is defo a WIP but when you trace the progress it's not too hard to envisage what the future will look like.

For the Fusion demo we intentionally didn't include the block or any accessories in the visualization as we wanted demonstrate Adam's ability to reason through the mechanical workings of an engine, like how the cams push the valves or the way the the crankshaft drives the connecting rods.

Re:Launch HN: Adam (YC W25) – Open-Source AI CAD on Wednesday June 17, 2026 @01:15PM (#48573456)
We could defo update our readme! What do you think of this?: https://x.com/aaronli/status/2064876123109089742?s=20

Fable 5 in our Fusion Extension.
