This page collects tools for making 3D assets with AI, and it splits them by what they produce. The first section lists services and models that build avatars and 3D objects from images or video, including Tencent's Hunyuan3D-2.1 with PBR materials. The middle section covers motion. Tencent's HY-Motion 1.0 is a text-to-motion model built on a Diffusion Transformer and Flow Matching, and the note lists its project page, GitHub repo, Hugging Face card, and technical report. The last section covers ForgeCAD, an AI-native CAD tool where parametric models are written in JavaScript so coding agents can generate and edit them. It notes the model-as-code API, the validation loop, the export formats, and the use cases.

CAD / Parametric Modeling
ForgeCAD
An "AI-native" CAD: parametric models are written in JavaScript (*.forge.js) instead of being built by hand in a GUI, so AI coding agents can generate and edit models directly.
- Model as code:
param()creates sliders, plus primitives and booleans (union/subtract),fillet(), patterns, a standard part library (lib.bolt(),lib.nut()generate real helical threads), and SDF (sdf.gyroid()) for lattices and organic shapes — all in the same language. - Validation loop: installs as a native CLI (
forgecad run bracket.forge.js), runs deterministic checks, and emits a report before manufacturing. - Export: STEP, STL, 3MF.
- Use cases: 3D-printed products, mechanical parts, assemblies/joints/colliders for robotics simulation, and generating model variants as AI training data for spatial reasoning.
- Website: https://forgecad.io/ #CAD #parametric #3D #robotics #agent
ForgeCAD keeps the model in a JavaScript file so an agent can edit it like source code. param creates sliders, and union or subtract combine primitives. fillet and patterns shape the part, while lib.bolt and lib.nut add real helical threads. sdf.gyroid builds lattices. The CLI runs deterministic checks and writes a report before export to STEP, STL, or 3MF.
