Many successful companies employ technical illustration to provide a clear and vivid explanation of product functionality in sales brochures user manuals and point of sale material.

CAD visuals can be used as a photo realistic image of a product before it is built. Cut-a-ways are an effective way of showing the outside and inside of a product.

Illustrations are the best way of showing a customer how to assemble a product or a service agent how to disassemble and reassemble - replacing parts if required.
