On paper, different drawing for each view is to be produced. Computer aided design or CAD used for designing objects with a computer.
5. Computers in manufacturing
Computers play important role in product design. In some factories, computers control virtually everything. Example, automobile plants use robots to perform tasks such as painting, welding and cutting and bending metal for body parts. Manufacturing with computers and Robotics is also called Computer aided manufacturing or CAM.
