What OpenPlan3D is
OpenPlan3D is a free browser-based editor for drawing floor plans in 2D and viewing them in 3D. Its drawing tools cover walls, rooms, doors, and windows, with measurements, grid snapping, and imperial or metric units. Designs can be furnished with more than 140 models or supplemented with imported GLB and glTF meshes. The editor can import Apple RoomPlan JSON scans and detect walls, doors, and windows in them. Plan exports include PNG, SVG, DXF, PDF, and JSON. OpenPlan3D Capture is an iPhone and iPad app that uses Apple RoomPlan; it requires an iPhone or iPad Pro with LiDAR and can save PNG, SVG, DXF, PDF, and USDZ files directly to the device. The maker says plans in the editor are stored in the user's browser rather than on its servers. The editor is open source under the MIT License, with source code available on GitHub. Its listed uses include real estate listings, remodeling, interior design, furniture planning, rentals, and CAD workflows.
