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 models in minutes without the freelance render cost. Builders cutting change orders. 3D print hobbyists making scale models for display or gifts.

Opening a saved plan, editing it and tapping Discard used to remove the whole plan from your account. It now puts the plan back exactly as it was when you opened it. • Sliding doors. A new door type in the editor, with its own plan symbol — and plans that already contain one now open correctly. • Curved walls. Room areas now follow the curve instead of measuring straight across it, so the figure matches the room you drew. • Half walls, knee walls and loft edges. Wall heights now go down to 1.5 m. • Door heights now fit the wall they sit in, so the plan and the 3D render agree before you spend a render. ### 2.2.1 — 2026-08-04 Adjust any uploaded plan before you turn it into 3D. NEW • Wall Review now opens straight into the editor with every wall, door and window that was detected — adjust anything before you render • Add and delete doors and windows right in Wall Review • Set the scale from a distance you know. Size is estimated from door widths and can be off by 10-15% — measure one wall and the whole plan corrects • Draw your own floor plan from scratch on a snap-to-grid canvas: walls, doors, windows and rooms. No photo needed • Curved walls — draw an arc and dial in exactly how much it bends • Trace mode — import a floor-plan photo or PDF and draw right on top • Export your plan as a JPG or PDF with dimension lines, scale bar and compass • Cloud sync — your plans follow you across your phone and the web app • Switch between metres and feet at any time • Pick a PNG or JPEG from Files, not just Photos IMPROVED • Rooms are detected properly when walls cross • Your trace photo is locked once you start drawing, so a stray pinch can't shift it • Windows draw in blue and doors in green, so they're easy to tell apart FIXED • Traced plans keep their photo after you save and reopen them • Walls you draw match the thickness of detected walls • 3D renders are no longer washed out on the sunlit side ### 2.2.0 — 2026-08-03 Adjust any uploaded plan before you turn it into 3D. NEW • Wall Review now opens straight into the editor with every wall, door and window that was detected — adjust anything before you render • Add and delete doors and windows right in Wall Review • Set the scale from a distance you know. Size is estimated from door widths and can be off by 10-15% — measure one wall and the whole plan corrects • Draw your own floor plan from scratch on a snap-to-grid canvas: walls, doors, windows and rooms. No photo needed • Curved walls — draw an arc and dial in exactly how much it bends • Trace mode — import a floor-plan photo or PDF and draw right on top • Export your plan as a JPG or PDF with dimension lines, scale bar and compass • Cloud sync — your plans follow you across your phone and the web app • Switch between metres and feet at any time • Pick a PNG or JPEG from Files, not just Photos IMPROVED • Rooms are detected properly when walls cross • Your trace photo is locked once you start drawing, so a stray pinch can't shift it • Windows draw in blue and doors in green, so they're easy to tell apart FIXED • Traced plans keep their photo after you save and reopen them • Walls you draw match the thickness of detected walls • 3D renders are no longer washed out on the sunlit side ### 2.1.0 — 2026-07-31 The floor plan editor is here, and it's free forever. Draw a plan from scratch on your iPhone or iPad — tap to place walls, add doors and windows, curve a wall into an arc, and let Ritn3D name each room as you close it. Or load a photo or PDF of an existing plan and trace straight over it. Export as JPG or PDF with dimension lines, a scale bar and a compass, then convert to 3D whenever you want. Also new: switch between metric and imperial, rename plans from My Plans, cloud sync across your devices, and a "Trace it instead" option when the AI can't read a photo. ### 2.0.4 — 2026-07-05 • Ritn3D now speaks 13 languages — including yours. • Fixed a share-sheet crash on iPad. • Small polish across the app. ## More apps by Rajesh Konatala - [Open3D: STL & 3D Model Viewer](https://appshunter.io/ios/app/open3d-stl-and-3d-model-viewer/id6772109964) All apps by Rajesh Konatala: https://appshunter.io/developer/1882436576 ## Related topics [floor plans pdf](https://appshunter.io/ios/topics/floor-plans-pdf) · [3d floor plan design](https://appshunter.io/ios/topics/3d-floor-plan-design) · [floor plans house](https://appshunter.io/ios/topics/floor-plans-house) · [floor plan creator house](https://appshunter.io/ios/topics/floor-plan-creator-house) · [floor plans grapholite](https://appshunter.io/ios/topics/floor-plans-grapholite) · [floor plans making](https://appshunter.io/ios/topics/floor-plans-making) · [3d drawing plan](https://appshunter.io/ios/topics/3d-drawing-plan) · [home design app free floor](https://appshunter.io/ios/topics/home-design-app-free-floor) · [3d floor plan creator](https://appshunter.io/ios/topics/3d-floor-plan-creator) · [wallpics 3d](https://appshunter.io/ios/topics/wallpics-3d) · [3d scratchpad](https://appshunter.io/ios/topics/3d-scratchpad) · [apps to draw plans](https://appshunter.io/ios/topics/apps-to-draw-plans) · [3d print house](https://appshunter.io/ios/topics/3d-print-house) · [home design app free plan](https://appshunter.io/ios/topics/home-design-app-free-plan) · [home layout app](https://appshunter.io/ios/topics/home-layout-app) · [aplicacion para aser planos de casa](https://appshunter.io/ios/topics/aplicacion-para-aser-planos-de-casa) · [floor plans sketch](https://appshunter.io/ios/topics/floor-plans-sketch) · [free layout floor](https://appshunter.io/ios/topics/free-layout-floor) · [3draw](https://appshunter.io/ios/topics/3draw) · [design maker architect](https://appshunter.io/ios/topics/design-maker-architect) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
