CAD

(pronounced: kad)

Also referred to as "Computer-Assisted Design," CAD software is a program used by architects, engineers, and 3-D artists who want to visualize and manipulate the objects or spatial environments they are designing. CAD systems make it possible to view a design from any angle and to zoom in or zoom out for close-ups or long views. If the user changes one value in a graphical model, the system automatically changes all of the other values that depend on it. One of the most popular of these programs is AutoCAD by AutoDesk.
