How to Create a Reflected Ceiling Floor Plan

The vector stencils library Registers, drills and diffusers contains 47 symbols of rectangular, circular, linear and troffer air handling inlet/ outlet components.
Use the design elements library Registers, drills and diffusers to draw reflected ceiling plans (RCP) and HVAC layout floor plans using the ConceptDraw PRO diagramming and vector drawing software.
"A ceiling is an overhead interior surface that covers the upper limit of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the floor or roof structure above.
Ceilings are classified according to their appearance or construction. A cathedral ceiling is any tall ceiling area similar to those in a church. A dropped ceiling is one in which the finished surface is constructed anywhere from a few inches to several feet below the structure above it. This may be done for aesthetic purposes, such as achieving a desirable ceiling height; or practical purposes such as providing a space for HVAC or piping. An inverse of this would be a raised floor. A concave or barrel shaped ceiling is curved or rounded, usually for visual or acoustical value, while a coffered ceiling is divided into a grid of recessed square or octagonal panels, also called a "lacunar ceiling". A cove ceiling uses a curved plaster transition between wall and ceiling; it is named for cove molding, a molding with a concave curve." [Ceiling. Wikipedia]
"... reflected Ceiling Plans (RCP)s showing ceiling layouts appear after the floor plans." [Plan (drawing). Wikipedia]
The shapes library "Registers, drills and diffusers" is contained in the Reflected Ceiling Plans solution from the Building Plans area of ConceptDraw Solution Park.

This reflected ceiling plan (RCP) sample shows lighting and HVAC layout.
"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."
