Thank for your reply, but i still can't find what i am looking for in the options view model.
I am looking for the following :
For each zone created, there is in plan view a label with the name of the zone, its surface and as optional parameters the material name of the walls, the florr, etc... I would like to show in this label the name and the materials of the wall and the floor, but not the surface.
Is it possible?
