The summary ceiling plan in Revit is reduced from the filing space under the ceiling. All systems should not only be interconnected, but also the distance between the grilles and the fire sensors, between the ducts and the fire sensors, between the lights and the fire sensors should be maintained. Between the sprinklers and the air ducts. Fire supervision thoroughly checks these regulatory distances. Therefore, the summary plan in Revit ceilings is the most important stage in the interconnection of engineering networks. This file regulates the arrangement of ceiling elements. Elements_folk_rev01
