Architects Engineers Car designers Town planners Kitchen Planners The list is endless …………………. CAD / CAM ? Many industrial systems link the computer aided design system to their computer aided manufacturing process so that the complete process from design to manufacture can be automated. This is known as CAD / CAM. Computer Simulation What is a Computer Simulation? ? A computer simulation is a system which has been created to behave as if it is real life. ? Simulations are often used to test conditions that could be dangerous, expensive or life threatening if the “real thing” was used.
