What's in here

I generate a wall-mounted headphone hook from scratch in this video. The workflow is simple: describe what you need, refine with follow-ups, and correct specific dimensions. All in plain English.

Describe, don't design

Tell GrandpaCAD what you need in plain English. Include dimensions when they matter.

Automatic engine selection

GrandpaCAD picks the right engine for the job. Functional parts get routed to parametric CAD, so they're dimensionally accurate and watertight.

Iterative refinement

Keep chatting to add features, adjust dimensions, or fix problems. Context carries forward between messages.

Prompts from this video

Copy these prompts to try the same workflow yourself.

  1. 1

    Wall mounted headphone hook, 40mm wide, 3mm thick walls

    Describe what you need with dimensions

  2. 2

    Add two mounting holes, 4mm diameter, 30mm apart

    Refine by adding details in follow-up messages

  3. 3

    Make the hook curve deeper, 25mm instead of 15

    Correct specific measurements conversationally

Try it yourself

Open GrandpaCAD and paste the first prompt. That's it.
