Engineering animations may be used as tutorials for courtroom purposes or to illustrate products and their functions.

A courtroom tutorial can illustrate how systems operate when they are complex or difficult to see with conventional video. Systems can be broken down to their component parts and slowly assembled to illustrate their working relationships. Transparency and color can be used to highlight key componenets.

Product animations can illustrate an existing product or one in the design or manufacturing process. They are useful for getting approvals or for product brochures or web advertising.
