Actual 3 dimensional models made of paperboard or cardboard can help as well. In some
cases, the models are built in actual scale. Such models sometimes are used as preliminary

Materials to build 3D models
(e) Virtual Prototyping (VP)
VP enables animation, showing, for example, the operation of a product, in a computer screen.
Computer software can even simulate the handling of product for immediate responses to the
audience in an interactive mode.
