Design elements - Pipes (part 2)

The vector stencils libraries "Pipes 1" and "Pipes 2" contain 28 and 48 pipe, tubing and fitting symbols, respectively.
"Pipe is hollow cylinder used to conduct or transfer fluids (liquids and gases) from one place to other place. The main difference between pipe and tube is the critical dimension used to describe the pipe size or the tube size. For pipe, internal diameter (ID) roughly corresponds to the nominal pipe size for standard wall thickness. For tube, the outer diameter (OD) closely corresponds to the tube size. In current European standards pipes and tubes are nowadays described as outside diameter by wall thickness. The three standard types of pipe ends used in the piping industriesare; Plain Ends (PE), Threaded Ends (TE) and Beveled Ends (BE). In the past, many types of material have been used in conveying water from one point to another. Masonry and wood were probably the first materials used. Plastics are the newest, and are now being used quite extensively." [Piping. Wikipedia]
Use the design elements libraries "Pipes 1" and "Pipes 2" for drawing plumbing and piping building plans, schematic diagrams, blueprints, or technical drawings of waste water disposal systems, hot and cold water supply systems using the ConceptDraw PRO diagramming and vector drawing software.
The shapes libraries "Pipes 1" and "Pipes 2" are contained in the Plumbing and Piping Plans solution from the Building Plans area of ConceptDraw Solution Park.

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]
