Many a great idea has first taken shape as a simple drawing sketched by hand on a piece of paper, but in an increasingly high-tech world, such drawings are more often being created--or at the very least perfected--with the aid of a computer. And in today's highly automated workplace, manufacturing a finished product from that great idea will likely require assistance from a computer-based tool. In this article, the author defines computer-aided design (CAD) and computer-aided manufacturing (CAM) and relates career opportunities in these growing fields. Additional resources are listed at the end of this document, to learn more about some of the companies whose products are used in CAD/CAM.
