From 2D Napkin Sketch to 3D Model — The Secret iPad Pro Workflow

Oct 11, 2025

 You know those freehand design sketches we all make on napkins—or these days, on our iPads—the ones where proportions feel right but there’s no literal scale?

In my latest video, I show you exactly how to turn those sketchiest, funkiest napkin drawings into accurate, to-scale 3D models using nothing but your iPad.

The process starts in Procreate or Morpholio Trace, where I’ll show you how to add a quick digital scale, export your sketch, and then import it directly into SketchUp for iPad—no desktop required. You’ll see how I align, scale, and set out guides that make it easy to start modeling walls and forms in real 3D space.

What I love most about this workflow is how natural it feels. You’re not abandoning the freehand energy that made the idea exciting—you’re just giving it structure.

And here’s the kicker: all of it happens on one device.
No exporting, no file conversions, no mouse clicks—just pencil, sketch, and scale.
