The term CAD/CAM is a shortening of Computer-Aided Design (CAD) and Computer-Aided Manufacture (CAM). The term CAD/NC (Numerical Control) is equivalent in some industries. Most CAD/CAM software was developed for product development and the design and manufacturing of components and molds, but they are being used by architects with greater frequency. CAD/CAM software uses CAD drawing tools to describe geometries used by the CAM portion of the program to define a toolpath that will direct the motion of a machine tool to machine the exact shape that was drawn.
