The Elements of a CAD System

Abstract

The key component in any CAD system is, by definition, a computer. The fact that it may also be the one which is superficially the least obtrusive makes it all the more important to remember that all the rest of the paraphernalia which go to make up a complete system play a subsidiary role. The different kinds of display technology and the various combinations of input and output devices, which we will be discussing later in the chapter, are basically no more than a means of ensuring that the interaction between designer and computer should be as easy, efficient and effective as possible.
