Cad-induced changes in design work

Abstract

CAD systems are a new aid for design processes that can be used to solve both simple and complex tasks. Sometimes, it is possible to perform tasks, such as the dynamic simulation of movement and finite element analysis, which could not have been done without the aid of computers. But, even the ability of the computer to perform less time-consuming tasks leads to changes in design activities. Advances in design methodologies and organization have been made, leading to better fulfillment of functions, better manufacturing-oriented design, and better scheduling of design and manufacture. Using computers for design, new design processes have become possible due to the computational speed and large storage capacity of modern computers, and to advances in software. The process of merging conventional and computer-aided design processes for a new computer-aided design technology is not finished: a methodology based on CAD still has to be developed. This paper will explain some developments in CAD systems that are changing the design activities. The aim of CAD systems development is to change the need for the designer to work within the limited possibilities of today's CAD systems. In the new systems, support will be easier and the information will be better integrated so that they can better serve the design demands.
