Hi,
Sorry about my English.
I've just discover this impressive (free!) software and thanks to the developers and the community.

I found un objet(shelves_storage_steel.obj : http://www.sweethome3d.com/models/contributions/shelves_storage_steel.zip ) and I found very pratical the internal editor of the sofware but I would like to go further and know if it's ("easily") possible to customize this objet or aoother similar and :
1) modify the numbers or trays
2) the gap between the trays

I did download MeshLab, Blender, ArtOfIllusion and I suppose i can be done with this sofwares but it will be too time consuming for me if however I can get there...

Thank you for your "magic" solution [:D]
