What OpenPlan3D is

OpenPlan3D is a free floor-plan editor that runs in a browser, with tools for drawing layouts in 2D and viewing them in 3D. Create walls, rooms, doors, and windows with measurements, grid snapping, and imperial or metric units. Furnish designs with more than 140 models or import GLB and glTF meshes. The editor can also import Apple RoomPlan JSON scans and identify walls, doors, and windows in them. Export plans as PNG, SVG, DXF, PDF, or JSON; DXF exports are described for use with AutoCAD and other CAD software. OpenPlan3D Capture for iPhone and iPad uses Apple RoomPlan and requires a Pro device with a LiDAR sensor. It saves PNG, SVG, DXF, PDF, and USDZ files directly to the device. The editor’s plans are stored in the browser, according to its maker. The project is open source under the MIT License, and the maker says there is no account requirement, premium tier, or paywall.
