How to Create a Floor Plan with Your iPhone

Q: Do I need to know how to draw or use CAD?

No — the plan is generated from the scan. Walls, doors, windows, openings and 16 kinds of furniture are detected automatically and drawn to scale. There's nothing to sketch and nothing to trace.

Q: What's the difference between the USDZ and PDF exports?

PDF (and JPEG) export the 2D top-down plan — best for printing, emailing and listings. USDZ exports the 3D model, which opens in Apple's Quick Look and 3D tools like Cinema 4D or Shapr3D. JSON exports the raw captured-room data for developers.

Q: Can I edit the floor plan after scanning?

You can rename the project and add address and author details, and view the plan in 2D or 3D from any angle. The geometry itself comes from the scan — if a wall looks off, the fix is a quick rescan of that area rather than manual redrawing.

A floor plan used to mean graph paper, a tape measure and an afternoon — or CAD software and a learning curve. With LiDAR it means walking around the room while your phone draws.

Before you start

Device: a LiDAR iPhone or iPad — Pro models (see the device list).
Light: normal room lighting is fine; LiDAR brings its own lasers, but the camera still helps recognition.
The room: open doors between areas you want captured as one space; you don't need to tidy up.

The scan

Open RoomKit and choose Single Room (or Multi-Room with Pro for a whole floor — see the whole-house guide).
Hold the phone at chest height, slightly tilted down, and sweep along each wall as you walk the room's perimeter.
Watch the live outline: walls, doors, windows and furniture appear as they're captured. Anything missing? Point the camera at it again.
Finish. The plan generates in seconds.

What you get

A 2D top-down plan with wall dimensions — the classic blueprint view, pan/zoom with your fingers.
An interactive 3D model of the same scan — orbit around it to sanity-check the geometry and see detected furniture in place.
The measurement sheet: surface area, volume, perimeter, plus counts of rooms, bedrooms, bathrooms, doors, windows and objects.
Project metadata: name, address and author — useful when plans go to clients or listings.

Export it

Four formats from the share sheet, each with a job:

PDF — US-Letter, print- and email-ready. The format for listings, landlords and contractors.
JPEG — the 2D plan as an image, for messages and docs.
USDZ — the 3D model; opens in Apple Quick Look and tools like Cinema 4D, Shapr3D and AutoCAD-compatible pipelines.
JSON — the raw captured-structure data, for developers and archival.

Scan quality tip: move slowly and keep walls in frame — speed is the enemy of clean geometry. If a wall comes out kinked, rescanning the room takes less time than fixing it any other way would.

FAQ

Do I need to know how to draw or use CAD?

No — the plan generates from the scan, to scale, automatically.

What's the difference between the USDZ and PDF exports?

PDF/JPEG are the 2D plan; USDZ is the 3D model for Quick Look and 3D tools; JSON is raw data.

Can I edit the floor plan after scanning?

Metadata yes (name, address, author); geometry comes from the scan — rescan an area to correct it.
