| Computer-aided design (CAD) is deployed for designing real and virtual objects. CAD frequently involves more than just shapes. The output of CAD frequently must also contain symbols, for instance processes, dimensions and tolerances according to application-specific conventions. CAD may be deployed to design curves and figures in 2-dimensional (2D) space, and curves, surfaces and solids in three-dimensional (3D) space. Computer-aided design is extensively deployed in a number of applications, including automotive, ship-building and aerospace industries, industrial and architectural design, prosthetics and others. CAD is also widely deployed to make computer animation for special effects in movies, commercials and technical instructions. CAD is deployed for designing tools and machines and for drafting and designing all kinds of architectural structures, from residential buildings to large commercial and industrial buildings, such as hospitals and factories. Computer-aided design is primarily used for detailed engineering of 3D models and 2D drawings of physical components, but it is also deployed in the engineering process. Computer-aided design has become an exceptionally significant technology among computer-aided technologies, because it spares time and money. In the late Eighties when the CAD programs became readily available, there started massive redundancies in drafting departments of small and mid-size firms. A CAD operator could supplant three-five drafters deploying traditional technologies. Moreover, many engineers started to do their own drawing projects, hence the need for traditional drawing departments vanished. As a result of, a great many drafters were laid off. Being high-priced, the advances were primarily bought by large companies. Hence, small businesses were unable to contend against giant companies that widely deployed CAD. At present, prices are lower. Even high-end packages need less expensive platforms and some even support multiple platforms. |
