Ritn3D converts 2D floor plans into interactive 3D models that users can explore, walk through, and share. It accepts PDF, JPG, and PNG plans, including CAD exports, scans, and photos of printed plans. Neural networks detect walls, doors, windows, and rooms; users can review and adjust the layout before model generation. The site says most conversions take under two minutes, depending on plan complexity. Shared models open in a browser viewer without requiring recipients to install the app or log in. The free plan includes three renders per month, a bird’s-eye view, standard textures, and sharing with up to five people. Pro costs $9.99 a month and includes 20 renders per month, walkthroughs, furniture, Full HD, sharing with up to 50 people, no watermark, and 90-day cloud sync. Pro+ costs $19.99 a month, with 40 renders and 10 GLB or STL downloads monthly; extra downloads cost $3.99 each. Free renders remain available for seven days. Each upload currently creates one floor, and hand-drawn or heavily annotated plans may need manual corrections. Ritn3D is listed for Android, iOS, web, and Windows.
