(CAD) orcomputer-aided design and drafting
(CADD), form of automationautomation,automatic operation and control of machinery or processes by devices, such as robots that can make and execute decisions without human intervention. The principal feature of such devices is their use of self-correcting control systems that employ feedback, i.e.

The technology is used for a wide variety of products in such fields as architecture, electronics, and aerospace, naval, and automotive engineering. Although CAD systems originally merely automated drafting, they now usually include three-dimensional modeling and computer-simulated operation of the model. Rather than having to build prototypes and change components to determine the effects of tolerance ranges, engineers can use computers to simulate operation to determine loads and stresses. For example, an automobile manufacturer might use CAD to calculate the wind drag on several new car-body designs without having to build physical models of each one. In microelectronicsmicroelectronics,

Among the benefits of such systems are lower product-development costs and a greatly shortened design cycle. While less expensive CAD systems running on personal computers have become available for do-it-yourself home remodeling and simple drafting, state-of-the-art CAD systems running on workstations and mainframe computers are increasingly integrated with computer-aided manufacturingcomputer-aided manufacturing

computer-aided design
computer-aided design (CAD)
the use of COMPUTERS in the DESIGN of new components or products and in the re-design of existing products. Unlike hand drawings, CAD design specifications can be shown on a visual display unit and redrawn to produce different versions of the components or product. CAD can also be linked to computer-aided process planning (CAPP) to determine the best methods by which to manufacture a product. Moreover, a component or product can be subjected to various tests of strength, performance, etc. using computer-aided engineering (CAE) software without having to build prototypes; thus changes in product design can be made quickly and cheaply (see NEW PRODUCT DEVELOPMENT). CAD is particularly useful in designing and classifying components and products used in GROUP TECHNOLOGY production and in FLEXIBLE MANUFACTURING SYSTEMS. See COMPUTER-AIDED MANUFACTURING.computer-aided design (CAD)
The use of computer software to assist in performing standard architectural and engineering design services. Products range from the most basic shareware home design and landscaping software to sophisticated systems with three-dimensional flyover and walk-through capabilities,project budgeting,and timeline creation.
