About the unit:
Computer Aided Design (CAD) and Computer Aided Manufacture (CAM) have rapidly changed the way
that products are conceived, designed, manufactured, tested, evaluated and promoted. This option
explains these impacts in detail and also assesses their effect on the environment, society and
economics.
