What is CAD? - CAD stands for Computer Aided Design which uses specialist computer software to produce designs that are either real or virtual. These designs can be in 2D (two dimensions) or 3D (three dimensions).

Computer-aided design (CAD) is a computer technology that designs a product and documents the design's process. CAD may facilitate the manufacturing process by transferring detailed diagrams of a product’s materials, processes, tolerances and dimensions with specific conventions for the product in question. It can be used to produce either two-dimensional or three-dimensional diagrams, which can then when rotated to be viewed from any angle, even from the inside looking out. A special printer or plotter is usually required for printing professional design renderings.

The concept of designing geometric shapes for objects is very similar to CAD. It is called computer-aided geometric design (CAGD).

CAD is also known as computer-aided design and drafting (CADD)
