I have a little problem.

In 3D view in options, i can choose to show all levels of my house = no problem [:)]

But when i select show only selected floor then the 3D show me the selected AND the underlying floors also [:((]

i mean when i selected the basement:
i see only the base in 3D.

When i select the first floor:
i see the basement AND the first floor in 3D.

When i select the second floor:
i see basement AND first floor AND second floor in 3D.

Is there a system to see ONLY the selected floor
so when i select the second floor i see ONLY the second floor in 3D.

The solution that i have for the moment is to save al the floors in different file's.

Thanks for help en sorry for my bad english [:p]
