What is it?

CADAM is a web application that turns plain-language descriptions and reference images into 3D CAD models. The generated models are written as parametric OpenSCAD code, so the main dimensions show up as adjustable controls. Users can change a value with a slider and see the model update without regenerating it through the AI.

The OpenSCAD engine runs as WebAssembly inside the browser, so the editing and rendering workflow needs no local installation. Finished models can be exported as STL, SCAD, or DXF files. The project also bundles the BOSL, BOSL2, and MCAD OpenSCAD libraries and uses Three.js for the live preview.

The stack is React 19, TypeScript, TanStack Start, and Supabase for auth, storage, and PostgreSQL, with Anthropic Claude as the AI backend. Running it locally requires Node.js, the Supabase CLI, and API keys for the model providers.

Key features

  • 01Generates 3D models from natural language and reference images.
  • 02Exposes model dimensions as interactive parametric sliders.
  • 03Runs OpenSCAD in the browser via WebAssembly.
  • 04Exports models as STL, SCAD, or DXF files.
  • 05Includes BOSL, BOSL2, and MCAD libraries.

Use cases

  • Quickly prototyping mechanical parts such as knobs, brackets, or threaded fittings.
  • Creating a parametric starting point that can be tweaked for 3D printing.
  • Learning how OpenSCAD code maps to geometry without installing desktop software.

Quick start

  1. 1

    Clone the repository

    git clone https://github.com/Adam-CAD/CADAM.git
  2. 2

    Enter the project folder

    cd CADAM
  3. 3

    Install dependencies

    npm install
  4. 4

    Start Supabase, then run the development server

    npx supabase start && npm run dev

Things to know

  • Needs Supabase CLI, Node.js 20.19+ or 22.12+, and API keys for AI providers such as Anthropic to generate models.
  • Local setup also requires ngrok for webhook development.
  • Licensed under GPL-3.0, a copyleft license that requires derivative works to remain open source.
