I think you’ll find if you make more complex things with more than a few knobs to turn with this the model will just shit out

I've got it managing a reasonably complex project at the moment, the secret sauce is in the reference system that helps me guide the agent to look at specific parts of STEP file topology, and ignore the rest

@curtisfloras can u explain a little further , how do you set up your codex agents. the workflow ?

Jake Fitzgerald profil fotoğrafı
Jake Fitzgerald6 ay önce

@curtisfloras Yep! All you have to do is ask Codex or Claude Code to clone this repo into your project, then you’re good to go. The agent will read the AGENTS/SKILL files which tell it how to generate 3D models. Nothing fancy or opinionated.

Cool work! I’ve also been also exploring Text-to-CAD and some Python libraries recently, but I’ve encountered a real-world feedback from enterprises: what they need is the 2D CAD engineering drawings acutally, with detailed dimensioning (including tolerances), chamfers/fillets,

build123d has good state management and leans into modern Python standards that the models have lots of training data on!

@earthtojake This is cool! Can it produce x-wing drone bodies? OnShape is awful. It can’t produce rounded edges. They look like huge steps. No smooth gradient for wing angles running into drone body. Would this potentially be able to create that? I attached one for context.

To generate 3D models in Codex with text-to-cad: Start a new project, write your prompt for a 3D model, and include a link to clone the text-to-cad repo. Codex handles the rest. The repo is open source and all scripts / ui run locally. Link below.

You can build your 3D models directly from a prompt into Claude code. All thanks to this beautiful python project, build123 a parametric modeling framework for 2D and 3D CAD. It is built on the Open Cascade geometric kernel and it is suitable for 3D printing.

Yes, CAD! Releasing today – my second open-source project. With AI rapidly learning how to output 3d models, I feel like I needed an app that standardized the way I made fast iterations, controlled versions per-chat, custom tools and interactions per-project and files ready to print at home! You can fork the entire thing! Change what you don’t like or even contribute with some cool features 🫶. It’s not a full-CAD app yet. I’ve been focusing on UI/AI first and then iterate on editable mode. So many cool features I wanna add to this, you can’t even imagine.

Over the weekend, I added multiplayer "paint ball" dogfight to Tiny Skies, so players can fly around pelting each other with colourful paint balls, just for fun. I tried meshy and tripo to generate some 3D models for the game and the mesh vertices count are really high and lags the game a lot (probably because my game is a globe with thousands of objects - albeit mostly instanced). To my surprise, I found Gemini 3.1 Pro to be really quite good at generating good looking 3D models that are low in poly count. It generated 3D models at a much higher quality than Opus 4.6, Sonnet 4.6 and GPT 5.4. You can see the upgraded biplane models and some objects in the video below. #vibejam

When u use Fable / Opus to generate models it can be quiet a pain in the ass to do small iterations. I also needed a way for the model to easily visualise the results of what he built so he could iterate over it. So I built a custom model viewer it can access and where I can easily fine tune models manually if needed. Used it for my game Valoria

New open-source 3D world-generation model. I'm rendering a couple of worlds in the video, so check it out. You'll find the GitHub and the Hugging Face links to the model below. This is a multi-modal world model that you can use for a bunch of things: • To generate new worlds • To reconstruct worlds • To simulate 3D interactive worlds from a prompt, images, or a video You can edit the 3D outputs in Unity and Unreal Engine (they export as meshes, 3DGS files, and point clouds). You can also generate 3D characters in the world and walk around. Pretty fun stuff!

My buddy who works in CAD said AI isn't good enough for him yet. I took that as a challenge and wanted to prove to him this is a limitation of CAD tools, not the models. 3 beers later, we decided to try something out. Personal CAD software that builds CAD models. I'll let you be the judge...

KYRALL TURNS "I NEED THIS PART" INTO SECONDS, WITHOUT OPENING CAD you describe the part. the AI generates it. no SolidWorks. no Fusion. no hours of setup. why this matters to you: modeling a part in CAD is slow and technical. sketch, constrain, extrude, fillet — for every bracket, housing or fixture. and simple one-off parts eat the same ceremony every time. for an engineer, that bottleneck stalls the whole project. Kyrall skips it: → prompt → 3D part ready → exports to STEP and STL, the formats you already use → for when you need the geometry now, not in three days it doesn't compete with CAD suites on millimeter control. it competes on getting you to a usable part first. idea → part → keep building. link below :)

Introducing CADGenBench: measure how well AI systems produce engineering-grade 3D parts! While current models can generate 3D parts, they are far from precise enough to build functional parts. We built a benchmark to systematically measure their capabilities on two tasks: 1. Generation from an engineering drawing of a part 2. Editing: given an existing STEP file and a requested change The benchmark is tool-agnostic. It makes no assumptions about how you build the model. You can vary the LLM, and you can vary the environment. Use build123d, Onshape, Autodesk, or a model without an LLM entirely. We open sourced the scoring engine and a reference baseline on top of build123d. A collaboration between Hugging Face and Mecado! Submission space: Code repository:

Only if education could be this interactive ❤️‍🔥 I've had a looong wish to build something genuinely useful through vibe coding, and I finally did it. A 3D human anatomy application built with Three.js using GPT 5.6 Sol. It all started with a single design image that I created using GPT Image 2.0. I then used it to generate every 3D organ image, one by one. Next, I converted each of those images into 3D models using Tripo (and no, they didn't sponsor this 😄). After that, I opened Codex, wrote a master prompt based on the design, and gave it the prompt, the design image, and all the 3D models. Codex built the first version beautifully, but there was one big problem. Every single 3D model was nearly 120-150 MB. That obviously wasn't practical for the web and was giving a performance of 16fps. After a few iterations, Codex optimized each model down to roughly 2–5.5 MB while preserving the visual quality, reducing the total asset size from ~900 MB to just 28.6 MB. And each model loads on demand. Along the way, Codex also generated those anatomical illustrations showing where each organ sits in the human body, and even created the interactive hotspot markers that explain different parts of every organ. It handled all of that. The process wasn't exactly one shot, but it also wasn't difficult. You just have to do it step by step. It genuinely felt like building something that could make learning anatomy much more engaging. The inspiration came from Dilum Sanjaya's 3D animal plant cell project. I remember seeing it and thinking, "I want to build something like this one day." And I did it :D Live: Code:
