It emphasizes shared CAD “language” by prescribing predefined layers, uniform graphic symbols, and consistent terminology for mechanical, plumbing, and fire protection information.

embraces the idea that computer-aided design (CAD) has become indispensable to the architecture/ engineering/ construction (AEC) industry. Not only has CAD software improved drafting efficiency and the overall productivity of the construction professional, but now building owners are realizing the potential of automated controls and electronic record keeping and are requesting data in electronic format from construction professionals.  \nNow that they have learned to communicate with the computer, many designers and builders are using computers to improve communications with each other. In order to share electronic information efficiently, it’s essential that all parties speak the same language. For members of the endorsing organizations, it’s important that the mechanical, plumbing, and fire protection information be labeled and located consistently in CAD files so that it is easily found and manipulated. For building owners and design professionals, it’s important that such data be consistently stored within their own CAD files in accord with a mutually agreed protocol or standard. To ensure consistency it is important to organize data into predefined “layers”, to apply identical graphic symbols to components, and to use consistent terminology and abbreviations.  \nSCS is designed to encourage consistency by building upon the second edition of the National CAD Standard (NCS) published by the National Institute of Building Sciences in 2001. NCS incorporates the efforts of the American Institute of Architects (AIA) and its CAD Layer Guidelines as well as the Construction Specifications Institute (CSI) and its Uniform Drawing System. As an organization with contributing members on the NCS Committee, SMACNA is committed to improving electronic communication between members of the AEC community and the overall quality of their work.  \nIn this current edition ofSCS, SMACNA has extended NCS by drawing upon the considerable experience of its own CADD Task Force. SCS articulates the CAD standards that will enable SMACNA members and the rest ofthe AEC community to apply CAD effectively to mechanical, fire protection, and plumbing design and construction.  \nThis document is available in electronic format by accessing [http://www.smacna.org](http://www.smacna.org on the)[ on the](http://www.smacna.org on the) Internet.  \nSHEET METAL AND AIR CONDITIONING CONTRACTORS’NATIONAL ASSOCIATION, INC.  \n SMACNA CAD Standard 􀀁 Second Edition iii  \nCADD TASK FORCE  \nRichard E.
