So we have legit text to 3d objects/cad/blender
but why is there not an equal for text to PCB/circuitry ? I tried one last year and it was not good at all.

Read through the McMaster catalogue.
My coworker was given this advice when they first started their mechanical engineering and design job. They originally thought it was some kind of hazing and after an hour of reading couldn’t put it down.

Isn't it fairly obvious? Art is completely abstract and permissive, while PCBs have real world constraints

Here is the full prompt for that part:
>The main cylinder axis is vertical along Z and centered at the origin.
>Create a central barrel with diameter 36 mm and height 70 mm, bottom at Z = 0.
>Around the barrel, add 12 horizontal circular cooling fins. Each fin is 2 mm thick in Z, has outside diameter 62 mm, and is spaced every 5 mm from Z = 10 mm to Z = 65 mm.
>Add a thicker base flange at the bottom, outside diameter 70 mm and thickness 8 mm, with six vertical mounting holes of diameter 5 mm on a 56 mm bolt circle.
>Add a top cap cylinder, diameter 44 mm and height 8 mm, from Z = 70 mm to Z = 78 mm.
>Add an angled spark-plug boss protruding from the side of the top cap. The boss is a cylinder of diameter 12 mm and length 24 mm, angled upward at 35 degrees from horizontal, with its axis pointing outward in the positive X direction.
>Add a 5 mm diameter hole through the boss along its own axis.
>Add small 1 mm fillets to the outer fin edges and base flange edges.
And the description still falls short, such as no room between the flange and fins to install nuts.
What a nightmare to describe all this in text! when the language of drafting is able to describe it perfectly, wordlessly and unambiguous, in a single drawing sheet. Yes, there are a few thing to learn beyond "draw a picture", but it's not a lot.
You can claim it's for "people who don't know CAD", but I have my doubts that those same people without those skills would be able to describe what they want in text.

#45Does something similar exist for buildings and Bonsai or FreeCAD with IFC?

#47I've been using Claude Opus 4.7 into OpenSCAD for creating hacked connectors for vibrating mesh nebulizers. It's incredibly powerful but still needs heavy manual checking to generate anything usable, but holy COW is it powerful when armed with the right info.
I've been playing around with this recently too and started getting much better results when I told it how to produce rendered PNGs of the file and to inspect it from several angles during iteration. I'm really only just getting going with it though, so if you have any tricks to share, I'd love to hear them!

genius, I have started doing this on web app test suites + playwright in other projects, makes a lot of sense to render shots from all the sides and ortho view and then feed that back to Opus 4.7 or similar as a smoke test.
I'm using it to rough out the skeletons for nebulizer power connector adapters so just throwing a lot of caliper measurements at it with detailed descriptions and reference photos of the connectors I'm duplicating has gotten me far.

#49Awesome tool! I gave it a spin last night and it worked surprisingly well. But apparently the AI had a different rotation view on the item as the stl browser preview? i tried to make a bottle-holder with the opening on top (which makes sense) and the whole element was rotated 90° to the side. i tried verifying with the AI and it said the opening was on top in their view when crosschecking against my screenshots. was…
This issue is fixed by the way!
Re: Text-to-CAD
#50In the benchmarks, there is a strange lack of measurements that I'd expect in a CAD process (EG in benchmark 1, the positions of the 4 holes are not specified at all). I'm assuming that's why the gussets in benchmark 3 overlap the holes and make a part that cannot be used. Does it actually handle positions correctly? Also the through-hole in benchmark 7 doesn't actually go through by the looks of the gif
The actual prompts are more detailed than what's in the table on the main page: https://media.githubusercontent.com/media/earthtojake/text-t... I'm just wondering why anyone would bother describing CAD models in text. Language is imprecise and ambiguous. If you want to create a full part definition, you need to be extremely thorough with your description. At that point it's just easier (less mental load) and faster t…
Not intentionally deceptive, the prompts are just too big to include on the home page!
I actually used GPT 5.5 Pro to generate the prompts from simpler one sentence prompts, so hypothetically it’s just an extra step in the harness for an agent to unpack / add detail to a prompt based on the user’s goal.
