Computer-aided design (CAD)
Computer-aided design (CAD) is a computer technology that designs a product and documents the design process. Cad can facilitate manufacturing processes by transferring detailed product diagrams, processes, tolerances and product dimensions to specific conventions for the product in question. It can be used to create two-dimensional or three-dimensional diagrams that can then be rotated to view from any angle, even from within. A special printer or plotter is often required to print a professional design render.
