Upload Your PDF
Import your floor plan PDF directly from your device. Ritn3D reads vector and raster PDFs alike, extracting wall lines at the document's native resolution for maximum accuracy.
PDF to 3D in seconds
Convert PDF Floor Plans to 3D Models
Turn architectural PDF floor plans into fully interactive 3D interior models. Ritn3D processes your PDF at full resolution, preserving the crisp vector lines and precise measurements from your original document. The AI detects walls, rooms, doors, and windows directly from the PDF and generates a realistic 3D model you can explore, walk through, and share.
How It Works
Three simple steps to your interactive 3D model
- 2
Review Detected Layout
The AI parses your PDF and identifies structural elements automatically. Review the detected walls, doors, windows, and room labels, then fine-tune anything that needs adjustment.
- 3
Generate 3D Model
Generate your interactive 3D model with one tap. Explore every room in orbit or walk-through mode, then share a browser link with clients or collaborators.
Everything You Need
Professional 3D visualization made simple
High-Fidelity PDF Processing
Ritn3D reads your PDF at native resolution, whether it contains vector graphics from CAD software or high-resolution raster scans. No quality loss during import.
Multi-Page PDF Support
Upload multi-page PDF documents and select the page containing your floor plan. Ritn3D handles standard architectural PDF exports from tools like AutoCAD, Revit, and SketchUp.
Automatic Wall Detection
The AI identifies wall lines, openings, and room boundaries from your PDF layout automatically. Clean architectural PDFs achieve high detection accuracy with minimal corrections needed.
Interactive 3D Exploration
Orbit around your model or walk through rooms at eye level. The interactive viewer gives you a true spatial understanding that flat PDF drawings cannot provide.
Share Without Software
Generate a shareable link that opens your 3D model in any browser. Clients and stakeholders can explore the space interactively without installing any applications.
Frequently Asked Questions
Everything you need to know. Can’t find the answer you’re looking for? Feel free to reach out.
Architectural PDFs exported from CAD software like AutoCAD, Revit, or SketchUp produce excellent results thanks to their clean vector lines. Scanned PDFs also work well as long as the scan is legible and the walls are clearly defined.
Yes. When you upload a multi-page PDF, Ritn3D lets you select which page contains the floor plan you want to convert. Each page is processed independently at its native resolution.
Higher quality PDFs with clear wall lines and minimal annotations produce better detection results. Vector PDFs from CAD tools generally give the best accuracy, while low-resolution scans may require more manual adjustments in the review step.
Ritn3D detects wall positions and room proportions from the visual layout of your floor plan. While it maintains accurate relative proportions, the 3D model is generated at a normalized scale rather than preserving exact metric dimensions.
The AI focuses on detecting structural elements like walls, doors, and windows. Furniture symbols and text annotations are filtered out during detection. Heavily annotated plans may occasionally need minor corrections in the review step.
