Computer-aided design (CAD) is the use of computer technology for the design of objects whether 2D or 3D, real or virtual. It is heavily utilized in many applications, including animation, automotive, shipbuilding, aerospace industries, industrial and architectural design, prosthetics, and many others. 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.
