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.
Tell GrandpaCAD what you need in plain English. Include dimensions when they matter.
GrandpaCAD picks the right engine for the job. Functional parts get routed to parametric CAD, so they're dimensionally accurate and watertight.
Keep chatting to add features, adjust dimensions, or fix problems. Context carries forward between messages.
