Engineering is the process of turning ideas or drawings into programs that can be run by computer controlled machines. With the use of a computer aided drafting program engineers are able to turn basic dimensions into three-dimensional representations of the parts. Through this process they generate a code that is read by the machines on how a part should be built.
Engineering is also able to create detailed drawings that help to aid the production crew. Engineering takes a basic drawing and starts the process to transform the idea into a reality.
