In the late 1980s, The Boeing Company committed to build the 777, a twin-engine, wide-body passenger jet. The forward thinking leaders at Boeing chose to design that airplane without the traditional class 3 physical mockups that made the design, planning, and manufacturing so expensive. They chose, instead to use 100% electronic mockup with the Computer Aided Design(CAD) being done on Dassault Systemes' CATIA product.
