Complex and intricate designs always demand viewing at various angles and different perspectives, to get a better understanding of it. Computer Aided Design is a mix of computer hardware and software that allows an engineer or technical designer to draw complex scaled drawings to particular specifications. In addition to the necessary CAD software, a CAD system must provide high-quality digital imagery via a good-to-excellent quality monitor; highly accurate printing to scale, often via a specialty printer; and the means to input data, either via scanner, light table, or light pen. A CAD program is a computerized drafting board. Computer-aided design or drafting software (CAD) is a convenient computer program allowing users to draw objects with exact precision. It is used for multiple applications at home and in the workplace. CAD has a steep learning curve, but once the basic functions are mastered it is an invaluable and even fun tool. Anyone who enjoys challenging puzzles can pick up a CAD program and bring objects to life with a few clicks of the mouse.

Video game animators use CAD Animation programs to bring characters to life. Animators construct three-dimensional objects and plot paths to simulate movement using CAD techniques. Drawing and creating storyboards are also important features for creating video games, all of which may be done with the aid of CAD programming. Graphic designers rely on CAD programs to visually communicate in print and multimedia. Designs for illustrations and advertisements are drafted using layout principles and design concepts achieved with CAD.
