Glossary (Version 8.4)

A representation that describes, simplifies, clarifies or provides an explanation of the workings, structure or relationships within an object, system or idea.

This can be either a physical model, such as in a scalemodel of a car or house, to show the form of a final production design, and is made with tools, jigs and fixtures; or virtual, such as a simulator program that demonstrates the capabilities of a vending machine through interaction with a computer user.
