Ritn3D

Draw a floor plan on your phone, or turn a photo of one into a walkable 3D interior in under two minutes. Upload JPG, PNG, or PDF. No CAD software, no 3D modeling skills, no install required. The editor is free forever with unlimited plans. Draw from scratch, trace over an existing plan, or upload one and let Ritn3D detect it — then convert to a 3D model you can walk through and share as a link. Built for phones first — iOS, Android and web on one account. Sketch on-site, generate the walkthrough on the way home. DRAW A FLOOR PLAN — FREE, UNLIMITED Tap to start a wall, tap to end it. Chain walls into rooms and each enclosed space is named automatically. Add single doors, double doors, open doorways and windows. Curve a wall into an arc when the room isn't square. Alignment guides keep it straight, undo and redo cover the whole session, and drafts auto-save so you can stop mid-room and come back. Export as JPG or PDF — unlimited, no watermark, on every plan including free. TRACE AN EXISTING PLAN Load a photo, screenshot or PDF as a tracing guide and draw your walls straight over it. Ideal for paper plans, hand-drawn sketches, and old blueprints. CONVERT A FLOOR PLAN PHOTO TO 3D 1. UPLOAD. JPG, PNG or PDF floor plan in seconds. 2. REVIEW. Walls, doors, windows and rooms are detected automatically. Fix anything off in the side-by-side editor. 3. GENERATE. An interactive 3D model and walkthrough in under 2 minutes. WALK THROUGH EVERY ROOM Walk at eye level with on-screen joystick controls. Judge sight lines, corridor widths and room proportions as you would standing in 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 and desks. Every piece carries real-world dimensions — check whether a king bed fits past the closet door before you buy it. SWAP WALL AND FLOOR FINISHES Sprayed paint, plaster, wallpaper, laminate, hardwood, stone, carpet, tile. What you pick shows up in the app, your GLB download, and the links you share. SHARE A LIVE 3D LINK Opens in any browser — no install, no login. Recipients view it on phone, tablet or laptop and see exactly what you see. 3D PRINT YOUR HOUSE Export print-ready STL with manifold geometry and sealed walls, slicer-ready for Cura, PrusaSlicer, Bambu Studio and Lychee.
