Illustrations from CAD data, supplied or generated can produce images that are difficult or even impossible to achieved photographically. Achieving a consistent theme across different scales, balancing lighting and colours, creating exploded views and cutaways are where CGI renderings excel.

Often used for brochures and specification cut sheets, where hundreds of products need the same background and material finish etc, or showing how a product will look in different colourways or with applied graphics the uses are multiple but always consistent - even when no product actally exists.
