reflected ceiling plans
Plans that are viewed from above, but laid out as if they were projected downward onto the back of an upper surface, such as a ceiling. In such a plan all members seen on the left from below appear on the right in the plan. The term also refers to plans for ceilings depicted as if reflected in a mirror on the floor, within the context of the floor plan, with the goal of illustrating how the ceiling design or configuration relates to the floor plan.
