What's in here

In this video I generate a protective cradle for an Arduino Uno. GrandpaCAD automatically searches for the real board dimensions, mounting hole positions, and port locations. I didn't open a single datasheet.

Auto-search for specs

GrandpaCAD looks up real-world dimensions (board size, mounting holes, port locations) so you don't have to.

Engineering intent

Parts are built with actual specs, not guessed shapes. Mounting holes line up. Port cutouts are where they should be.

Beyond text-to-3D

This isn't shape generation. It's CAD with real-world data baked in, backed by specs instead of approximations.

Prompt from this video

Copy this prompt to try it yourself. GrandpaCAD will search for the real Arduino Uno specs automatically.

Describe the part and the AI searches for real board dimensions

Try it yourself

Open GrandpaCAD and describe any part that fits a real-world component. It'll look up the specs for you.
