In Archicad 20, I'm making a reflected ceiling of a level with a loft and some drop ceilings drawn with the slab tool. I've set up a 3D Document with floor plan projection set to "reflected ceiling" Objects above and below the height of the slabs are visible, and the layer the slabs are on is turned on. Is there a setting somewhere to make slabs visible when "reflected ceiling" is checked? Some of the slabs are on the story the 3D document was created and others are one story up.
