Ritn3D

Ritn3D converts existing floor plans into interactive 3D layouts for homeowners and property professionals who want to review or share a design without building a model from scratch. It is a focused single-floor tool, not a fit for projects that need multi-storey output or generous model-export allowances.

Overview

The service uses neural networks to identify walls, doors, windows, and rooms in PDF, JPG, and PNG plans, including CAD exports, scans, and photos of printed drawings. Users can check and adjust the detected layout before generation, which is valuable when recognition misses a detail. The company says most conversions take under two minutes, though complex plans can take longer.

Generated models are interactive and can be explored or walked through. Shared models open in a browser, so recipients do not need an app or an account. The FAQ says uploads are processed securely and not shared with third parties; shared links are access-controlled and revocable. Free renders remain available for seven days, while Pro includes 90-day cloud sync.

Key features

• Plan recognition with correction: Automatic detection can reduce the work of tracing a plan, and the review step gives users a chance to fix the layout before generating a model. Hand-drawn or heavily annotated plans may still need manual corrections.
• Interactive browser sharing: Recipients can explore a model without installing software or signing in, a practical advantage for client or household review.
• Single-floor conversion: Each upload creates one floor only, so multi-level projects require a different workflow.
• Design integrations: Ritn3D can embed its editor and viewer in another product; partner API arrangements are discussed with prospective partners. This is aimed at product teams, not ordinary individual use.

Pricing

Ritn3D has a free plan and month-to-month paid plans, plus a 7-day trial. The listed starting price is $14.99/user/mo, while the plan prices below are published separately.

Free suits occasional layout checks, but three monthly renders, bird’s-eye viewing, and seven-day render retention constrain ongoing collaboration. Pro is the step up for users who need walkthroughs, higher sharing limits, and longer cloud sync. Pro+ is for heavier render use or downloads, though its ten included GLB/STL files per month make frequent exports a metered cost. Enterprise is the relevant option for organizations seeking custom volumes or an embedded, branded experience.

Platforms

Ritn3D supports Android, iOS, web, and Windows. It accepts floor-plan images rather than creating a floor plan from a text prompt; image-to-floor-plan and measurement input are supported. Export formats include JPG, PDF, GLB, and STL.

Who it's for

Real estate agents can share an explorable view of a property layout, while architects, interior designers, builders, and homeowners can use it to review a proposed or existing single-floor plan. It is less suitable for teams whose core need is detailed multi-floor modelling, or for plans whose hand-drawn or heavily annotated content would require substantial correction.

Pros and cons

Pros

• PDF, JPG, and PNG input covers CAD exports, scans, and photographed printed plans.
• Layout review before generation allows corrections to detected architectural features.
• Browser sharing avoids requiring recipients to install an app or create an account.
• Pro provides walkthroughs and 90-day cloud sync, while Pro+ includes GLB/STL downloads.

Cons

• Uploads produce a single floor, limiting its usefulness for multi-storey projects.
• Hand-drawn and heavily annotated plans may need manual correction.
• Free includes only three renders per month and seven days of render retention.
• Pro+ limits included GLB/STL downloads to ten per month, with extra downloads priced at $3.99 each.

Alternatives

Planner 5D is worth considering if a broader design workflow matters: its Premium plan includes floor-plan upload and conversion to a 3D project, alongside a full premium furniture catalog, for $59.99 a year billed Pay annually.

RoomSketcher is another option for users who want both 2D and 3D floor plans and snapshots; its Free plan includes one AI floor-plan conversion and two starting credits.

Treform is an alternative for users seeking a different AI editing and rendering workflow, with a free plan and a Student quarterly plan at $69 a month billed billed once per term.

CubiCasa may suit users whose priority is a 2D floor plan with room dimensions and PNG or JPG output; its LITE plan is free.

Luw.ai Studio is an alternative for users looking for general AI image creation, with a free tier that provides two daily credits at 512×512 resolution and includes a watermark.

FloorLens is worth comparing for scan-based sharing and exports: its free plan includes one web scan and PDF, image, 3D model, and MP4 exports, with the link and QR code auto-deleting after 14 days.

CamPlan is an alternative for users who want a LiDAR-based room-planning workflow, with one project per month on its free plan.

Drafted is another option for users seeking free PDF, CAD, or BIM downloads, with a separate free add-in for Revit 2025 and 2026.

Verdict

Choose Ritn3D when you need to turn an existing single-floor plan into an interactive model that is easy to share and can be corrected before generation. Its combination of file-format flexibility and account-free browser viewing is compelling for quick review; look elsewhere for multi-storey output or frequent, high-volume model exports.
