National CAD Standard is voluntary, however adopting companies and agencies can require its use by their associates. National CAD Standard The National CAD Standard (NCS) is a collaborative effort in the United States among computer-aided design (CAD) and building information modeling (BIM) users. Its goal is to create a unified approach to the creation of building design data. Development of the NCS is open to all building professionals in a collaborative process led by the buildingSMART Alliance. The NCS is composed of CAD layer guidelines from the American Institute of Architects, uniform drawing system modules from the Construction Specifications Institute, and BIM implementation
Computer-aided dispatch mobile data terminals (MDTs) or mobile data computers (MDCs). CAD systems consist of several modules that provide services at multiple levels in a dispatch center and in the field of public safety. These services include call input, call dispatching, call status maintenance, event notes, field unit status and tracking, and call resolution and disposition. CAD systems also include interfaces that permit the software to provide services to dispatchers, calltakers, and field personnel with respect to control and use of analog radio and telephone equipment, as well as logger-recorder functions. Computer-assisted dispatch systems use one or more servers located in a
