CAD
Computer-Aided Design (CAD)
Computer-Aided Design (CAD) is a technology used in the design of structures, sites, and machines (just to name a few). CAD replaced hand drafting as the preferred method of designing during the 1990's. For visualization, CAD files can be created in either 2-D or 3-D, enabling the use of fly-through technology for viewing designs before they are constructed. CAD is a vital part of the BIM process in that extractions produced from BIM rely on CAD processes for generating construction documents.
