How to create 3d model for a house with 2 levels, and have the architectural plans for each level as a floor to that level
Hi,

I am using SweetHome3D-6.0 to build a 3d model, of a house with 2 levels, with architectural plans for each level.

I create the first level like so:
- Add the architecture plan for the first level as background image (Plan -> Modify background image),
- Create rooms and walls on top of the background image
- Display the background image (Plan -> Modify rooms -> Display floor)
- Export to 3d model (3D View -> Export to OBJ object)
The result is a level1.obj file, which I can open with e.g. meshlab with the architecture plan displayed - good!

I create the second level by repeating the steps, but replacing the first level architecture plan, with the second level architecture plan
If I export all levels into allLevels.obj file, meshlab shows the 2 levels with the first level architecture plan, as background image.
If I export level2 into level2.obj file, meshlab shows the level2 without any architecture plan, as background image.

How can I create allLevels2.obj, so that the second level architecture plan, serves as background image for the second level?

Thanks,
Avner
