Manufacturing giant Siemens AG of Germany owns NX, Solid Edge and a host of supporting CAM, CAE, ECAD, and PLM programs – plus the crucial kernel and constraints programs Parasolid and D-Cubed. Today, no significant CAD software is owned by a manufacturer, although some manufacturers run in-house CAD systems strictly for internal use. Unigraphics was enhanced by aircraft manufacturer McDonnell Douglas, and now is known as NX at Siemens PLM Software. Catia was developed by Dassault Aviation, and now is the flagship MCAD program for Dassault Systemes. Figure 1: Siemens PLM Software CEO Tony Hemmelgarn speaking at the opening keynote session at the company’s annual PLM Connection Americas 2018 Conference.Many MCAD software programs were incubated in the 1970s and 1980s by the colossi of manufacturing, but were later spun off when those players no longer wanted to be in the software business.ĬoCreate, for example, was created by HP but is now known as Creo by PTC.
