OpenPlan3D review
A free, capable home design tool for simple multi-floor planning and Apple AR workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenPlan3D is a free, open-source tool for drawing 2D floor plans and turning them into 3D home designs. It is aimed at homeowners, renovators, interior designers, real estate professionals, and others planning spaces. The browser-based editor supports walls, doors, windows, snapping, undo and redo, while its iPhone and iPad companion app supports Apple RoomPlan and LiDAR imports. Multi-floor building design, furniture placement, and 3D visualization make it suitable for residential layout work rather than a narrow room-sketching task.
Its strongest advantage is the combination of accessible planning tools and Apple-focused capture and AR features. Users can place, resize, and rotate 140+ furniture models, then inspect designs with orbit, pan, zoom, textures, lighting, and shadows. Apple RoomPlan and LiDAR imports can turn captured rooms into editable floor plans, while USDZ export supports Apple Quick Look. The product also supports GLB and glTF mesh imports, giving users a way to bring additional 3D assets into a design.
Export coverage is another practical strength for different planning and documentation workflows. OpenPlan3D can export PNG, SVG, DXF, PDF, JSON, and USDZ files, supporting printed plans, vector work, CAD workflows, structured data, and Apple AR viewing. Its main constraint is platform coverage: the product runs on the web and iOS, so it is best suited to Apple users who want straightforward home design and AR-ready outputs. Choose it for free multi-floor planning with Apple capture and export options; consider an alternative if you need broader platform coverage or a more specialized professional ecosystem.
