cad - Computer Definition
The use of computers and software in design work. CAD is used extensively in architecture, aeronautical engineering, civil engineering, electrical engineering, genetic engineering, mechanical engineering, facilities planning, and interior design.
(Computer-Aided Design) Using high-speed desktop computers to design products. Either a mouse or graphics tablet is used for the physical drawing, and a scanner may be attached for additional input. The output of a CAD system is often electronically transmitted to a computer-aided manufacturing (CAM) system or 3D printer, which builds the objects (see CAD/CAM and 3D printing). Generic or Specialized CAD software is available for generic design or specialized uses, such as architectural, electrical and mechanical. The software may also be highly specialized for creating products such as printed circuits and integrated circuits. Solid and Parametric Modeling More complex forms of CAD are solid modeling and parametric modeling, which allows objects to be created with real-world characteristics. For example, in solid modeling, objects can be sectioned (sliced down the middle) to reveal their internal structure. In parametric modeling, objects have meaningful relationships with each other (a door must be on a wall, not the floor; holes cannot be drilled too close to the edge, etc.). See wireframe modeling, surface modeling, solid modeling, parametric modeling, graphics and CAE.
