OpenPlan3D

What it is

OpenPlan3D is a free floor plan editor that runs in a web browser, with tools to draw layouts in 2D and view them in 3D. You can add walls, rooms, doors, and windows, set measurements, use grid snapping, and work in imperial or metric units. For furnishing a design, the editor includes more than 140 models and can import GLB and glTF meshes. It can also import Apple RoomPlan JSON scans and identify walls, doors, and windows in those scans. Export a plan from the editor as PNG, SVG, DXF, PDF, or JSON; DXF exports can be used with AutoCAD and other CAD software. OpenPlan3D Capture is the iPhone and iPad app for RoomPlan scans. It requires an iPhone or iPad Pro with a LiDAR sensor and saves PNG, SVG, DXF, PDF, and USDZ files directly to the device. OpenPlan3D supports multi-floor design and AR visualization. Its plans are stored in the browser, according to the maker. The editor is open source under the MIT License, with source code on GitHub. It is built and operated by the independent studio theLodgeStudio.
