Technology Computer Aided Design (CAD) can make the design of buildings, homes, car engines, and aircraft by using the Graphics Pads. Graphics is an input input pads for drawing objects on the monitor. Graphics pads used to have two types. First, using a needle (stylus) which is connected to the pad or pads using low voltages, which are included on the bearing surface of the touch-sensitive membrane (touch sensitive membrane surface). Low voltage that is sent is then translated into the coordinates of X - Y. Second, using a touch sensitive pad (touch sensitive pad) without using needles. The way it works is to put on a pad of drawing paper, and inscribed in pencil.
