## What is RoomTrace 3D?

Turn a real room into a 3D space you can inspect, save, and share by following simple on-screen guidance.

RoomTrace 3D is designed for people who want an easier way to scan indoor spaces. There are no complex settings to learn. Turn on the lights, walk slowly around the room, and follow prompts for distance, movement speed, and lighting while the app recognizes walls, openings, and common furniture.

GUIDED SCANNING
• A short three-step preparation guide
• Live prompts for distance, speed, and lighting
• Visible counts for recognized walls and objects

3D VIEWING
• Rotate and zoom the space as soon as scanning finishes
• Review walls, doors, windows, and recognized objects
• Keep recent scans saved locally on your device

FLEXIBLE EXPORT
• Export USDZ for Apple devices and AR viewing
• Export an OBJ material package for tools such as Blender and CAD
• Save or send files through the system share sheet
