Reflected ceiling plan

"A "reflected ceiling plan" shows a view of the room as if looking from above, through the ceiling, at a mirror installed one foot below the ceiling level, which shows the reflected image of the ceiling above. This convention maintains the same orientation of the floor and ceilings plans - looking down from above. Reflected Ceiling Plans or RCP's are used by designers and architects to demonstrate lighting, visible mechanical features, and ceiling forms as part of the documents provided for construction." [Floor plan. Wikipedia]
The reflected ceiling plan example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Reflected Ceiling Plans solution from the Building Plans area of ConceptDraw Solution Park.
