TextoCAD

TextoCAD is an AI-powered text to CAD engine that turns plain English descriptions into editable parametric models and exports files for 3D printing.

TextoCAD is a source-available text to CAD engine that generates CadQuery and OpenSCAD scripts from plain English prompts. Users can describe a part in natural language to receive an editable model with named dimensions, allowing adjustments without making new AI calls. It supports four distinct modes including printing, precision, organic, and robotics for different design requirements. The software works with various AI providers such as OpenAI, Anthropic, Google Gemini, xAI, DeepSeek, OpenRouter, Mistral, Groq, Together, and Fireworks. It exports formats like STEP, STL, GLB, 3MF, and URDF for manufacturing, robotics, and 3D printing.
