Hello!
i would like to receive your tips about the extension Buildingbook or "Gebäudebuch" (in german). It belongs to the same extension as Roombook and Areabook.
We have a relative big project with 9 floors, and we would like to calculate the preliminary costs of it by getting first the volume of each wall, ceilings, etc. sorting them by material.
I have used a while the Buildingbook and it seems to work well, but what i cannot find is the option for floor ceilings! the same for floors covering. I just can select the suspended ceiling. I´ve chosen all the levels but they still dont appear..as I cannot see them on the list of Families and Types. How could I include them in the calculation, so I know how much concrete or isolation do they have?
Many thanks for your help! 
Victor
