A display from a computer-aided design (CAD) package showing the layout of a ventilation system in an underground facility at the CERN research centre, Geneva. CAD is invaluable in designing the optimum layout of such systems, as changes to the design may be effected instantly and the impact on the overall facility may be quickly determined. In this image, the ventilation trunking may be seen in purple.
