The Computer in Design and Graphics Computers are widely used in engineering and related fields and their use is expected to grow even more rapidly than in the past Engineering and technology students must became puter literate, to understand the applications of puter and their advantages. Not to do so well place students at a serious disadvantage in pursuing their careers. Computeraided design (CAD) involves solving design problems with the help of Computer: to make graphic images on paper with a plotter or printer, analyze design data, and store design information for easy retrieval. Many CAD systems perform these functions in all integrated manner, greatly increasing the designer39。s productivity. Computeraided design drafting (CADD), an offshoot of CAD, is the process of Generating engineering drawings and other technical documents by puter and is more directly related to drafting than is CAD. The CADD user inputs data by keyboard and/or mouse to produce illustrations on the monitor screen that can be reproduced as paper copies with a plotter or printer. Engineers generally agree that the puter does not change the nature of the design process but is a significant tool that improves efficiency and productivity. The designer and the CAD system may be described as a design team: the designer provides knowledge, creativity, and control。 the puter generates accurate, easily modifiable graphics, performs plex design analysis at great speed, and stores and recalls design information. Occasionally, the puter may augment or replace many of the engineer39。s other tools, but it cannot replace the design process, which is controlled by the designer. Depending on the nature of the problem and the sophistication of the puter system, puters offer the designer or drafter some or all of the following advantages. 1. Easier creation and correction of drawings. Working drawings may be created more quickly than by hand and making changes and modifications is more efficient than correcting drawings made by hand. 2. Better visualization of drawings. Many systems allow different views of the same object to be displayed and 3D pictorials to be rotated on the CRT screen. 3. Database of dr
