Launch HN: Adam (YC W25) – Open-Source AI CAD
GitHub zachdive ● Covered by 2 sources
Adam, a Y Combinator W25 startup, launched CADAM, an open-source AI platform that generates 3D CAD models from natural language prompts and converts them to parametric OpenSCAD code. The system supports multiple AI models (Claude, Gemini, GPT) with in-browser WebAssembly compilation and exports to .STL, .SCAD, and other formats. Users can now generate mechanical designs through text descriptions and adjust dimensions with interactive sliders without requiring new LLM calls.
Why it matters
Hey HN! I'm Zach from Adam (https://adam.new/). We're building AI agents for mechanical CAD software. We’ve built the company on two fundamental beliefs:- AI will be the primary medium for creating mechanical designs just like it is in software today.- The best paradigm for CAD generation is to generate CAD as code (text -> code -> CAD).We’re building CADAM, an open source Text to CAD platform. It's a React app (TanStack Start) with a Supabase backend for auth, database, and file storage. Think of it like AI TinkerCAD.Demo: https://www.youtube.com/watch?v=iESOr7EGWqk Try it: https://adam.new/cadam/What it does:- Generates parametric 3D models from natural language, with support for both text prompts and image references.- Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension tweaking- Exports as .STL or .SCAD (plus OBJ, GLB/GLTF, FBX, and DXF)Under the hood:- One agentic endpoint with two modes that swap system prompts a
