Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. The design of geometric models for object shapes. CAD is more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD often must convey also symbolic information such as materials, processes, dimensions, and tolerances, according to application-specific conventions. CAD may be used to design curves and figures in two-dimensional 2D space; or curves, surfaces, or solids in three-dimensional 3D objects.
CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising, technical manuals. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.
CAD/CAM Engineers use CAD to automate manual design processes in order to reduce the time consumed and dependence on human skills. This saves time, resources and ensures reliability and standardisation for the client.They work with service industries, utilities, construction, transportation, automotive and manufacturing industries. Alternatively, they can also find employment with consulting firms. related fields.
