Ritn3D: Floor Plan to 3D Model

Convert a 2D floor plan photo into an interactive 3D model in under two minutes. Upload JPG, PNG, or PDF. No CAD software, no 3D modeling skills, no install required.

The fastest way to convert a floor plan to 3D: phone-camera photos, scanned blueprints, screenshots from real estate listings, and architectural PDFs from AutoCAD, Revit, or SketchUp all work. Drag furniture in (Pro), share a live 3D link that opens in any browser, or export GLB or STL for 3D printing (Pro+).

HOW IT WORKS
1. UPLOAD. JPG, PNG or PDF floor plan to 3D 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. 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 so you can 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, in your downloaded GLB, and on the share links you send.

SHARE A 3D LINK WITH ANYONE
Generate a browser link to your 3D model. Recipients open it in any browser on phone, tablet, or laptop. No app install, no account, no friction. They get the same view 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.

GLB EXPORT
Standard 3D format that opens in Blender, SketchUp, Unity, and web viewers. Use Ritn3D as the conversion step, then refine in your existing 3D toolchain.

PBR TEXTURES AND PER-ROOM LIGHTING
Realistic walls, floors, doors, and windows with proper material physics. Warm per-room lighting and ambient shadows make the output look like a real space, not a wireframe.

EVERY COMMON FLOOR PLAN FORMAT
JPG floor plan to 3D, PNG floor plan to 3D, PDF floor plan to 3D, single-page or multi-page. Phone-camera photos of printed plans work. Screenshots from real estate listings work. Scanned blueprints work. Architectural PDFs from AutoCAD, Revit, and SketchUp work.

PRICING
Free plan with three 3D renders every month, no credit card required. Pro unlocks unlimited walkthrough mode, drag-and-drop furniture, HD textures, longer share lists. Pro+ adds GLB and STL downloads. Pro starts with a 7-day free trial.
