Built for Space Designer 3D Scan a room, generate a 6-character share code, and open the project in Space Designer 3D on the web with a single tap. Walls, openings, and furniture are preserved so you can start editing, furnishing, and rendering immediately — no remodeling required. Print-ready PDF floor plans, to scale Export dimensioned 2D plans directly from your iPhone. Every wall, door, window, and furnishing is rendered as a clean technical drawing with measurements in metric or imperial. Choose your scale (1:50, 1:100, 1:200) and share a PDF ready for clients, contractors, or permit submissions. Scan rooms in minutes Point your iPhone and watch the room build in real time. LiDAR automatically detects walls, doors, windows, openings, and common furnishings. Each scan is saved as a 3D model you can preview on the spot. Merge rooms into a full home Scan room by room and combine captures into a single, connected floor plan. Ideal for apartments, houses, offices, and any multi-room project where one big scan isn't practical. Organize scans into projects Group scans by property, job site, or client. Add an address, operator name, and notes so every project stays clear, searchable, and ready to revisit. Preview in 3D before exporting Rotate and zoom through a clean 3D view of each scan to verify accuracy before you export a PDF or share with Space Designer 3D. Works offline, syncs when you're back Scans are saved locally and sync automatically in the background. Capture confidently on-site, basement to attic, even without a connection. Sign in with Apple or email — your projects stay in sync across iPhone and iPad. Requirements iPhone or iPad with a LiDAR sensor. iOS 17 or later.
