Text-to-CAD that exports tweakable OpenSCAD code

What it does

CADAM is a web app that generates 3D models from plain-language prompts or reference images. It uses OpenSCAD compiled to WebAssembly for browser-side geometry evaluation, renders the result with Three.js, and lets you export as .STL, .SCAD, or .DXF. Adjustments happen via automatically generated parametric sliders that tweak dimensions without re-invoking the AI.

The interesting bit

Rather than producing a static mesh, the system keeps the model parametric. That means resizing a hole or thickening a wall happens locally in the browser—no second LLM call required. It is essentially a conversational front-end for a classic programmatic CAD engine.

Key highlights

• OpenSCAD WASM runs the geometry evaluation client-side
• Real-time preview via Three.js and React Three Fiber
• Supports both natural-language and image-guided generation
• Auto-extracted parametric controls for dimension tweaking
• Bundles BOSL, BOSL2, and MCAD libraries
• React 19 + TanStack Start frontend with Supabase backend

Caveats

• The README’s demo section is currently empty placeholder comments
• Self-hosting requires a broad collection of API keys (Anthropic, OpenAI, Google, FAL, etc.) plus Supabase and ngrok
• The “browser-based” claim applies chiefly to rendering; AI generation and auth are server-dependent

Verdict

Worth a look if you want generative CAD that stays parametric, or if you are building tools for the 3D-printing workflow. Skip it if you need a fully offline, zero-dependency modeler.
