Summary

CADAM is an open-source, browser-based web application transforming natural language and images into 3D CAD models. It targets designers and hobbyists seeking intuitive 3D asset creation, offering AI-powered generation, interactive parametric controls, and multiple export formats. The project leverages WebAssembly for in-browser CAD operations, aiming to simplify and democratize 3D modeling.

How It Works

CADAM employs AI to interpret natural language prompts and images, generating initial 3D geometry. This is rendered interactively using React and Three.js, with OpenSCAD compiled to WebAssembly (WASM) handling client-side CAD operations. Users can dynamically adjust model dimensions via parametric controls, benefiting from "smart updates" for efficient re-rendering. A Supabase backend supports data management and API interactions.

Quick Start & Requirements

Clone the repository, install Node.js dependencies (npm install), start Supabase services (npx supabase start), serve functions (npx supabase functions serve --no-verify-jwt), and run the dev server (npm run dev). Prerequisites include Node.js, npm, Supabase CLI, and ngrok. Environment variables for Supabase and Anthropic API keys must be configured.

Limitations & Caveats

Requires external API keys (Anthropic, Supabase) for functionality. Local development necessitates ngrok for webhook integration. The setup complexity and dependency on external services could be adoption barriers.
