From scan to design tools with USDZ

Every scan in Scanstead — single room or whole house — exports as a USDZ file with one tap. USDZ is Apple's flavor of Universal Scene Description, the same format Pixar built for film pipelines, and it's become the lingua franca for AR and 3D on Apple platforms.

What's in the file

The export isn't a raw mesh soup. It's the structured model: walls as walls, openings as openings, rooms grouped and positioned. That structure survives the trip into other tools, which makes it usable as a starting point rather than a reference photo.

Where it goes

  • Quick Look, instantly. Anyone with an iPhone or Mac can open a USDZ with no software — clients included. Text them the file; they can spin their house in AR on the kitchen table.
  • SketchUp / Blender. Import the model as your as-built base and design on top of it. The existing-conditions modeling session you used to bill a day for is now a lunch break.
  • Estimating workflows. Send the scan to the office directly from the app — measurements arrive structured, ready to price.

As-builts are the hidden win

Designers rarely lack ideas; they lack accurate existing conditions. A USDZ scan captured during the first site visit means the design conversation starts from reality — real wall positions, real window heights, real ceiling lines — on day one, not after a measuring appointment.
