What is the correct statement about floor plans and their vertical height reference used in drawing conventions?

• A. Floor plans are views of the building from above, shown at 60 to 72 feet above the floor.
• B. Floor plans are sectional views at 12 to 18 feet above the floor.
• C. Floor plans are sectional views at 42 to 48 feet above the floor.
• D. Floor plans are elevations of the roof at 30 to 40 feet above the floor.

Answer: (C)

Floor plans are horizontal slices through a building used to show the layout of a single level as if you’re looking down from above. In drawing conventions for this context, that plan comes from a sectional cut taken at a fixed vertical reference above the floor, so interior details like walls and door placements appear clearly on one level. The specific height range given in this context—42 to 48 feet above the floor—is the standard reference used to produce that plan view. This distinguishes floor plans from other views: they aren’t simply a view from above at a distant height, they aren’t low vertical sections, and they aren’t elevations of the roof.
