Computer Aided Design
An overview of Computer Aided Design (CAD).
INTRODUCTION
The aim of CAD is to apply computers to both the modeling and communication of designs. There have been two different approaches – which are often used together – namely:
?· at a basic level, to use computers to automate or assist in such tasks as the production of drawings or diagrams and the generation of lists of parts in a design;
?· at a more advanced level, to provide new techniques which give the designer enhanced facilities to assist in the design process.
The bulk of the development in CAD (computer aided design) has been in modeling the form of products (i.e. in providing techniques to assist in the representation of form using conventional drawings or new modeling techniques) or in systems to assist in the production of diagrams and the subsequent evaluation of designs represented by these diagrams.
The driving force behind the provision of computer assistance for conventional modeling techniques has been the desire to improve the productivity of the designer by the automation of the more repetitive and tedious aspects of design, and also to improve the precision of the design models.
