text-to-cad plugin extension is now live on codex! - generate 3D models as STEP, STL, 3MF, or GLB - DFM for printing, sheet metal, CNC, injection moulding - connect to fab services like bambu and sendcutsend 100% open source and free, runs locally inside the codex desktop app

to install: codex plugin marketplace add earthtojake/text-to-cad codex plugin add text-to-cad@earthtojake quit and reopen codex happy cadding

big thanks to @amypretzel for helping build the new ui and teaching me a lot about how professional mechanical engineers use these tools! we have more to share next few weeks

Testing it out right now

how does it feel to kill 100 startups in one tweet?

Having DFM checks for sheet metal and CNC built in is what makes this useful for real parts. Does it warn about stuff like bend radius before sending to a fab service?

yes it does! add /dfm before your prompt or just ask for a DFM check

A /dfm prefix is a nice touch, way easier than digging through settings. Being able to send straight to a fab service after the check closes the loop well.

this is sick

Nice work!

STEP + GLB local is the bit I care about. Testing a printable bracket tonight. OH YES.

I gotta find some time this weekend to try this out!

killing it @earthtojake - just killing it

Tools like this make me wonder: is there still a rational reason to go to university, beyond networking? Most of the practical knowledge and hands‑on examples are now available at home, without the fluff and bad‑mood professors.

Excited to send a sheet metal shop a part that only exists in a language model's imagination

xie xie nin

How accurate is this?

Because the plugin connects model generation to CAD formats, manufacturing checks, and fab services, a design can move from prompt to production workflow without leaving Codex.

How much token burn for a build like this ? Does it check assembly clearances too?

cool! how’s the dmf for complex organic shapes like my planters?

There is a PR up for organic-cad and organic shape generation, still a wip

cool

The standard-parts lookup in the repo is a nice touch. Starting with the actual screw or bearing dimensions beats designing a lovely bracket and then discovering the hardware aisle disagrees.

Very cool

@grok il s'agit de quel logiciel qu'il a utilisé ?

now the backlog needs shelf space

sick! open cascade as the geo kernel?

Yes boss

To me, assembly fit is where this gets really interesting. Can it check tolerance stack-ups between mating parts, or is that still a separate review?

thanks for building that I made a enclosure for my resin 3D printer with that no more fumes and poison in the air 🙏😭

This is a brilliant use of AI

If you need any help understanding how aerospace uses CAD or more about workflows beyond design feel free to ask, this is awesome. I’m a 20 yr experience in industry guy

OMG! I am gonna have so much fun recreating factories using this. This is fire 🔥

Do you plan to have the agent specific plugins end up being the recommended install method over npx package?

Planning to support the plugins and raw skill installs. Plugins give you nice ui support within a desktop client (Codex, Claude, etc) but both are valid setups! All of the code (including the ui to view STEP files) is in a Python package cadgen

DFM 别只看生成成功：3D 打印的最小壁厚和悬垂角、钣金的折弯半径，模型给的参数经常卡在工艺边界上，出图后还是得人工过一遍。STEP 比 STL 好在还能改特征，STL 只能重来。

Claude code mod coming?

I’m waiting on the Claude plugin review if any Anthropic friends can help @trq212 Exploring code mods this weekend

Could this click and prompt feature work in cursor or grok build?

yes, working on cursor plugin now. does grok build have a desktop app?

congratulations
