How It Works

Scan to 3D in Three Steps

Scan a room with iPhone LiDAR, get a floor plan and a 3D model, then edit and export them. Everything runs on your device.

01Step One

Scan with LiDAR

Open the app and walk slowly around the room. Your iPhone's LiDAR sensor and ARKit RoomPlan map walls, doors, windows, openings and furniture in real time, while on-screen guidance shows what is still missing. For cleaner results, the LiDAR scanning tips cover lighting, pace and difficult surfaces.

02Step Two

Automatic Floor Plan & 3D Model

When you finish the scan, LiDAR Room Scanner creates a 2D floor plan and a parametric USDZ model with room dimensions and total floor area. Nothing is uploaded to a server.

03Step Three

Edit & Export

Refine the plan in the editor: adjust walls, doors and windows, edit labels and measurements, and place furniture across three modes. Then export it in the format you need and share it through the iOS share sheet.

Object Capture for Single Objects

A separate mode for single objects. Instead of mapping a room, you walk around the object while the app takes photos, and your device reconstructs a textured 3D model with Apple's Object Capture. No internet connection is needed.

How Object Capture Works

Choose Object Capture, set the object on a flat surface and walk slowly around it while the app takes photos automatically. When you finish, your device reconstructs a textured 3D model; this runs on the device and takes a minute or longer. The model is saved to the same library as your room scans and exports as textured USDZ.

Tips for Accurate Scans

Use Even Lighting

Bright, even light helps the sensor read surfaces cleanly. Avoid dim rooms and strong glare from windows or mirrors.

Move Slowly & Steadily

A slow, smooth pace gives RoomPlan time to lock onto walls and furniture. Rushing leaves gaps the editor has to fix.

Cover Every Corner

Walk the full perimeter and pan up and down. Capturing each corner and opening produces a complete, accurate plan.

Mind Glass & Mirrors

Large mirrors and glass can confuse depth sensing. Approach them slowly and re-scan that area if geometry looks off.

Choose the Capture Mode

Standard keeps furniture exactly as scanned; High Fidelity replaces detected furniture with clean models. Measurements are identical in both modes.

Enable Location

Allowing location while scanning tags the plan with a true-north heading and address, so it is correctly oriented.

Common Questions

How long does a room scan take?
Capturing a room means one slow walk along its walls, so the time depends on the size of the room. The floor plan and 3D model are created on your device a few seconds after you finish, without an upload.
Which iPhones and iPads can scan?
Room scanning needs Apple's LiDAR sensor: iPhone 12 Pro or Pro Max or any newer Pro model, or iPad Pro from 2020 on, with iOS or iPadOS 18 or later. Object Capture needs the same iPhone models or an iPad Pro from 2021 on. The app itself installs on any iPhone or iPad running iOS 18; Building Studio, the floor plan editor and the library work without LiDAR.
Do I need an internet connection?
No. Scanning, floor-plan generation, editing and reconstruction all run on your device. You only need a connection if you choose to share an export.
How accurate are the scans?
iPhone LiDAR captures room geometry to within a few centimeters under good conditions, which is accurate enough for floor plans, furniture layout, real estate listings and as-built documentation. Even lighting and a slow pace give the best results; the capture mode does not affect accuracy.
Can I edit the floor plan after scanning?
Yes. The editor has three modes: Geometry to adjust walls, doors and windows, Labels to edit names and measurements, and Objects to place furniture. It includes undo and redo, grid snap and live measurements.
How is Object Capture different from room scanning?
Room scanning with RoomPlan maps an entire room into editable parametric geometry. Object Capture is a separate mode for a single object: you walk around it while the app takes photos, and your device reconstructs a detailed, textured 3D model from them. Both run entirely on your device.
