ABSTRACT
This chapter introduces computer-aided design (CAD) to those who are not yet familiar with either its capabilities or the computer hardware and software necessary for its implementation. The concept of CAD is similar in that it involves the storage of graphical primitives. The benefits to be derived from CAD systems encompass all stages of the design, drafting, and production process. CAD is appropriate for a wide range of design and drafting disciplines: architecture; civil engineering; interior design and office layout. Two main alternatives are available for the storage of CAD software and the drawing images and symbol libraries that are purchased or created. They are: floppy disks and hard disks. Two types of input/output ports are generally available for microcomputers: serial and parallel. The video display devices selected for a CAD microcomputer are a prime determinant of the overall cost of the system, because acceptable alternatives range from perhaps $600 to well over $5,000.
