MAC (Multi-Agent CAD): A decoupled multi-agent framework for text-to-CAD generation via constrained test-time compute
Using AI to generate 3D models
A curated list of valuable open-source CAD (Computer-Aided Design) software, libraries, and tools, organized by category.
Learning Hierarchical and Geometry-Aware Graph Representations for Text-to-CAD
CAD/CAE Copilot — an AI-native CAD/CAE/CAX workbench for AI agents. Text-to-CAD, text-to-CAE, real build123d/OpenCASCADE geometry, editable parameters, stable topology pointers, deterministic critique, and MCP server tools.
AI CAD 建模 Agent:一句话需求进来,调研、提问、出 BOM,逐件完成真实 CAD 建模并导出装配 STEP(参数化 BRep,不是图片或网格);几何与碰撞检查不过关就不交付。Windows 封闭 Beta。An AI CAD modeling agent: real parametric geometry from a one-line brief, gated by geometry and interference checks.
An open source harness for generating CAD models [forked of https://github.com/earthtojake/text-to-cad]
This project uses a Large Language Model (LLM) with Retrieval-Augmented Generation (RAG) to convert natural language descriptions into executable FreeCAD Python scripts for 3D modeling.
CATIA Works
Text23D Mechanical CAD Explorer is an AI-assisted mechanical design platform for generating and refining 3D parametric CAD models from conversational input.
AI-native CAD agent converting natural-language requests into validated OpenSCAD artifacts with automated geometry repair and manufacturing validation.
Free, MIT-licensed CAD for every discipline — parametric modelling, drawings, FEM, CAM, PCB and BIM, chat-driven and offline-first. No accounts, no cloud, no billing. Part of Vulos.
A reliable text/image to CAD Agent harness that supports different MCPs and LLMs
Anvilate is an open-source, local-first design agent for mechanical engineers. Describe a part in plain English and receive a physics-validated, parametric STEP or DXF file that drops straight into CATIA, SolidWorks, NX, or AutoCAD, alongside the editable Python source code.
