I am working on a 4 story building. I have already drawn all the walls, floors, roofs, Int. Stairs ect. I want to change the thickness of my floor composites and keep my ceiling heights the same. I am trying to find the best way to do this without having to manualy adjust everything. I know the stair settings will have to change. Any tricks on adjusting the floors & walls quickly? It seems unlikely that floor thickness would be set in stone at early DesDev stages. This must be common. Thanks
