Ritn3D Downloads & RevenueRitn3D: Floor Plan to 3D Home · App Store & Google Play

Draw a floor plan on your iPhone, or photograph one you already have. Either way you get an interactive 3D interior you can orbit, walk through, furnish and share with a link — in about two minutes. No CAD software, no 3D modeling skills.
Built for phones from day one — iPhone, iPad 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 space is named and measured automatically. Add doors and windows, curve a wall into an arc when the room isn't square, and let alignment guides keep it straight. Undo, redo and auto-saved drafts throughout. Export as JPG or PDF with dimension lines, a scale bar and a compass — unlimited, no watermark, on every tier including free.
TRACE AN EXISTING PLAN
Load a photo, screenshot or PDF as an underlay and draw your walls over it — the route for paper plans, hand-drawn sketches and old blueprints. If an upload fails detection, tap "Trace it instead" rather than starting over.
CONVERT A FLOOR PLAN PHOTO TO 3D
Upload a JPG, PNG or PDF. The AI detects walls, doors, windows and rooms automatically, you fix anything off in the side-by-side editor, and the 3D model generates in under two minutes.
WALK THROUGH EVERY ROOM
Walk at eye level with on-screen joystick controls. Judge sight lines, corridor widths and 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 — reflected in the app and on every share link.
SHARE A 3D LINK WITH ANYONE
Whoever you send it to installs nothing and creates no account. They open the link 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. Print at 1:200, 1:100 or 1:50 on FDM, SLA or SLS printers.
GLB EXPORT AND PBR MATERIALS
GLB opens in Blender, SketchUp, Unity and web viewers. Models render with physically-based materials, warm per-room lighting and ambient shadows — a real space, not a wireframe.
DETECTION ACCURACY (Ritn3D internal benchmark set, June 2026)
• Vector PDFs from CAD software: 90–95% first-pass
• Scanned blueprints: ~80%
• Straight-on phone-camera photos: 75–85%
• Listing renders with wood textures: under 30% — ask for the line-drawing PDF
• Hand-drawn plans: trace them in the editor instead
WHO USES RITN3D
Homeowners visualizing a renovation before swinging a hammer. Real estate agents turning a listing plan into a walkable link. Interior designers walking clients through a layout before anything is moved. Architects producing study model

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.
