Frequently Asked Questions
Everything you need to know about Ritn3D — pricing, features, file formats, sharing, and more.
General
Ritn3D is a mobile app that converts 2D floor plans (PDF or image) into interactive 3D interior models. Upload a floor plan, review the auto-detected layout, and generate a 3D model you can orbit, walk through, and share via a link — no CAD skills or 3D software required. Available on iOS and Android.
Ritn3D is available as a native app on iOS and Android. Shared 3D models open in any web browser — recipients do not need to install the app.
It works well on clean, legible floor plans — printed, digital, or PDF. Heavily annotated or low-resolution plans may need more manual corrections. Hand-drawn floor plans are not currently supported. The review step before generating lets you fix anything the detection missed.
Most floor plans are converted into a full 3D model in under two minutes. Processing time depends on the complexity of the plan — larger multi-room layouts may take slightly longer.
Ritn3D is built for anyone who works with floor plans — real estate agents, architects, interior designers, homeowners, and builders. No technical expertise is needed to get started.
Pricing & Plans
Ritn3D has three tiers. Free: 3 renders/month, standard quality, bird's-eye view. Pro ($9.99/month): 20 renders, Full HD textures, walkthrough mode, no watermark, 90-day cloud sync. Pro+ ($19.99/month): everything in Pro plus 10 STL downloads/month for 3D printing, GLB file exports, and commercial use rights. All paid plans include a 7-day free trial.
Free gives you 3 renders per month with a bird's-eye view, standard textures, and up to 5 share views per project (with a Ritn3D watermark). Pro unlocks 20 renders per month, Full HD textures, walkthrough mode, no watermark, up to 50 share views per project, and 90-day cloud sync across devices.
Yes. Cancel anytime through your App Store or Google Play subscription settings. No cancellation fees.
Yes — all Pro and Pro+ subscriptions come with a 7-day free trial. Cancel anytime during the trial and you will not be charged. The Free tier also lets you test the full pipeline (upload, detect, render, share) with 3 renders per month, no trial required.
Subscriptions are handled through the Apple App Store and Google Play Store, so any payment method accepted by those stores works — credit/debit cards, carrier billing, gift cards, and more.
3D Printing
Yes. Pro+ subscribers can export any generated 3D model as a print-ready STL file. The STL is a single watertight mesh — open it in your slicer (Cura, PrusaSlicer, Bambu Studio, OrcaSlicer), choose a scale, and print. No manual mesh repair needed.
Pro+ is $19.99/month and includes everything in Pro plus 10 STL downloads per month, GLB file downloads, and commercial use rights. Extra STL downloads are available at $4.99 each. It is designed for users who need physical scale models — 3D print shops, architects, and real estate agents producing keepsakes or presentation models.
You can export at 1:50, 1:100, 1:200, 1:350, or 1:500 — or enter a custom scale. The STL file is pre-scaled so you print without resizing in the slicer. A 1:100 single-floor model typically fits on a standard 220×220 mm print bed.
Download the STL and upload it to an online print service like Craftcloud, PCBWay, or JLC3DP. Many local libraries and makerspaces also offer 3D printing. Costs typically run $5–$20 per model depending on size and material.
Features
Walkthrough mode lets you orbit, rotate, and explore every room of your 3D model interactively — not just from above. It's included in the Pro plan.
Pro subscribers get 90-day cloud sync — your models are available across devices for 90 days. Free renders are available for 7 days after generation.
Pro+ subscribers can download their 3D models as GLB files — the standard format used by Blender, Unity, Unreal Engine, Sketchfab, and other 3D tools. GLB files preserve textures, lighting, and materials. Pro+ also includes STL export for 3D printing physical scale models.
Tap the share button on any saved project to generate a unique link. Recipients open it in any web browser and see your 3D model in an interactive viewer — no app install or login required.
Technical
Ritn3D accepts PDF floor plans, JPG images, and PNG images. Both digital and scanned floor plans work. Heavily annotated or low-resolution plans may need manual corrections in the review step. Hand-drawn floor plans are not currently supported.
Higher-resolution files produce better detection results. For scanned plans, 200 DPI or above is recommended. Blurry, cropped, or low-contrast images may require more manual corrections in the review step.
Yes. Your uploads are processed securely and never shared with third parties. Shared 3D model links are access-controlled and can be revoked at any time from within the app.
Currently, each upload generates a single-floor 3D model. For multi-story buildings, upload each floor separately. Multi-floor stitching is on the roadmap.
After detection, you can adjust walls, doors, windows, and room labels before generating the 3D model. This ensures the final result matches your floor plan even if the AI missed or misidentified elements.
