In 1991, the McDonnell Douglas Systems Integration groups, including Unigraphics, were acquired by EDS (then a part of General Motors Corp., later part of HP Enterprise Services, now part of DXC Technology). EDS branded the acquired business as EDS Unigraphics. Eventually, in 1997 EDS set up its Unigraphics division as a wholly owned subsidiary called Unigraphics Solutions. EDS took Unigraphics Solutions public while continuing to own majority controlling shares in Unigraphics. During this time, Unigraphics acquired a few companies itself including Engineering Animation, Inc., the former Ames, Iowa-based visualization company.
