Que : 11. Define the term CAD. What are the advantages of using CAD?
Answer:

CAD (computer aided design) can be defined as, “The use of computer systems to assist in the creation, modification, analysis or optimization of a design.”

Computer aided design is the technology concerned with the integrated design activities using a digital computer. This includes computer generation and modification of graphic images on a video display, analysis of design data, electronic storage and retrieval of design information and printing these designs as a hard copy on a plotter or printer.

The generation of design drawings interactively by the user supplying information to the computer via commands or with a menu driven series of instructions, is called computer aided drafting. These drawings can easily be edited, manipulated and stored for future usages.

ADVANTAGES OF COMPUTER AIDED DESIGN AND DRAFTING

The advantages of CAD are as follows:

1. High productivity with reducing lead time

2. Accurate designing

3. Standardisation of design

4. Modifications in designs are easy and quick

5. Automatic database creation assists in the creation of manufacturing documentation

6. Better control over the complete project

7. Better communication and presentation of design

8. Optimised solutions as a result of detailed engineering analysis
