What is the difference between floor plans and ceiling plans in Revit?

The distinction between floor plans and ceiling plans in Revit is primarily based on their focus and representation in the vertical space of a building. Floor plans are horizontal representations that depict various elements located at a specific level, typically showing walls, doors, furniture, and other components situated on that floor level. They provide a top-down view of the layout of spaces and the arrangement of elements on the floor.

Ceiling plans, on the other hand, specifically concentrate on the ceiling elements. They show details such as ceiling finishes, lighting fixtures, HVAC components, and other systems that are installed on or near the ceiling. Essentially, while both plans are horizontal views, ceiling plans are dedicated to the features that are above the floor and below the roof or structure.

This means that the understanding of floor plans primarily involves the functional use and organization of a room or space, while ceiling plans focus on the design and arrangement of the overhead elements. Hence, the correct option highlights this critical distinction, clarifying the specific purpose of each plan in Revit.
