Why convert HD3D to OBJ?
People want .obj because it is a universal 3D mesh format that opens in Blender, SketchUp and game engines. But .hd3d only holds Home Design 3D's parametric room, wall and furniture data locked to that app, with no geometry export, so there is nothing to translate straight into an OBJ mesh.
How to convert HD3D to OBJ
Rebuild in Sweet Home 3D and export OBJ FREE
Recreate the floor plan in the free Sweet Home 3D, then use 3D View > Export to OBJ format to get a mesh you can open elsewhere.
Recreate in Live Home 3D
Redraw the rooms in Live Home 3D, which can export the scene to .obj/.dae for use in other 3D tools.
Share as image or PDF instead
If you only need to show the design, use the Home Design 3D share icon to export a screenshot or plan image rather than a 3D model.

Open .OBJ details →Quality & what to watch
- There is no automatic converter: any OBJ result means manually rebuilding the layout in another program.
- Furniture and textures from Home Design 3D will not carry over; you get only geometry you model yourself.
- Measurements may drift slightly when you redraw, so double-check wall dimensions after rebuilding.
