I'm looking for a fast way to select all objects of a floor or building.
If a building is marked and space is pressed the visibility of all building objects is changed. I would like to select exact all these objects. The only way I found is to open all nodes (ALL, if a floor has nodes (roof) these has to opened too) click on the first object of the top (in widget) floor use shift and click on the last (in widget) floor.
Is there an easier way to select all objects of a building or floor in the gui.
