Ritn3D: Floor Plan to 3D Home

About

Floor plan photo to walkable 3D interior in under two minutes. Upload JPG, PNG, or PDF and Ritn3D generates an interactive 3D interior model you can orbit, walk through, drag furniture into, and share with a link. No CAD software, no 3D modeling skills, no install required for anyone you share with. Ritn3D is built for phones from day one — native iPhone, iPad, and web on one account. Take a photo of a floor plan on-site, generate the walkthrough on the way home. Every common floor plan format is supported: JPG or PNG photos of printed plans, single or multi-page PDF, scanned blueprints, and architectural PDFs from CAD software. How it works 1. Upload. JPG, PNG, or PDF floor plan. 2. Review. The AI detects walls, doors, windows, and rooms automatically. Fix anything off in the side-by-side editor. 3. Generate. An interactive 3D model in under 2 minutes. Walk through every room Walk at eye level with on-screen joystick controls. Evaluate sight lines, corridor widths, and room proportions the way you would standing inside the real space. Open doors. Look out windows. Stand in the kitchen and see the living room. Drag-and-drop furniture Place sofas, beds, dining tables, chairs, side tables, desks, and more. Every piece carries real-world dimensions — sanity-check whether a king bed fits past the closet door before you buy it. Swap wall and floor finishes Pick from sprayed paint, plaster, wallpaper, laminate, hardwood, stone, carpet, tile. What you choose shows up in the app and on the share links you send. Share a 3D link with anyone Share a live 3D link that opens in any browser — no install, no login. Recipients open it on phone, tablet, or laptop and see exactly what you see. 3D print your house Export print-ready STL files for 3D printing. Manifold geometry, sealed walls, slicer-ready for Cura, PrusaSlicer, Bambu Studio, and Lychee. Print at 1:200, 1:100, or 1:50 scale on FDM, SLA, or SLS printers.
