That software helped to develop Dassault’s Mirage fighter jet. CATIA started as an in-house development by French aircraft manufacturer, Avions Marcel Dassalt(AMD). Changes to the drawing were so key because the final output was so clean. It was debatable whether CAD was more productive than traditional techniques as it was all 2-dimensional. Only the most progressive companies had access to computer aided design. IBM even had a parametric sheet metal package in 1985-86 before PTC but they never took to market. Yamaha had developed a home grown system for product development, as well as Boeing & HP, because there was nothing on the market. In the 1960s, large Automotive and Aerospace companies began to develop their own proprietary CAD/CAM systems for internal use. Mainframe first followed by Unix based processors and Windows NT circa 1993 before moving on to Dell Precision mobile workstations. From 2D line drawings to 3D CAD tools and in turn, these always placed a demand on the speed and innovation of the computers that operate them. At Design-engine we call CAD communication tools. CAD communication tools have evolved over the past 60+ years.
