Overview

UGS Corp. was an American enterprise software company focused on product lifecycle management (PLM), computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), and related engineering collaboration technologies. Its roots reached back to United Computing, a software company founded in 1963 in Torrance, California. United Computing developed UNIAPT, released in 1969 and described as one of the earliest commercial end-user CAM products. It later acquired the ADAM drafting and machining code from MGS, using that technology as a foundation for UNI-GRAPHICS and the commercial Unigraphics product introduced in 1975. The business became part of McDonnell Douglas in 1976. Within the aerospace group, it was organized as the Unigraphics Group and expanded its CAD/CAM activities. The Unigraphics product evolved into a three-dimensional modeling platform, with a significant release in 1980. In 1991, the relevant McDonnell Douglas systems-integration activities were acquired by EDS, which operated the business first as EDS Unigraphics and later as Unigraphics Solutions. EDS established Unigraphics Solutions as a wholly owned subsidiary in 1997 and took it public while retaining majority control. During the EDS period, the company broadened its portfolio and corporate scope. It acquired Engineering Animation, a visualization software company, and acquired Applicon in 1999. In 2001, Unigraphics Solutions was renamed UGS. EDS subsequently repurchased the outstanding shares and acquired SDRC, a major former competitor, combining the two businesses into EDS PLM Solutions. This combination expanded UGS beyond its traditional CAD/CAM base into a broader product development and lifecycle-management platform. EDS sold EDS PLM Solutions in 2004 to a private-equity consortium comprising Bain Capital, Silver Lake Partners, and Warburg Pincus. Following the transaction, the business resumed operation under the UGS name and operated as an independent PLM software company. In 2005, UGS acquired Tecnomatix Technologies, strengthening its manufacturing-process planning and digital manufacturing capabilities. UGS's principal offerings included NX, a CAD/CAM/CAE suite, and Teamcenter, an integrated PLM and collaboration environment. Its wider portfolio included NX I-deas, NX Nastran, Solid Edge, Imageware, Tecnomatix, Jack, Femap, D-Cubed, JT, PLM Vis, PLM XML, and Parasolid. These products served engineering, manufacturing, product-data management, simulation, visualization, factory planning, and collaboration requirements across industrial sectors. On January 24, 2007, Siemens AG announced that it would acquire UGS for US$3.5 billion. Siemens completed the acquisition on May 7, 2007, and incorporated UGS's operations into its automation and industrial software activities. The business initially operated as the UGS PLM Software division within Siemens Automation & Drives and was later integrated into the Siemens Digital Industries Software organization. UGS therefore ceased to operate as an independent company, although its technologies and product lines continued within Siemens's industrial software portfolio.

History

UGS developed from United Computing, a software company founded in 1963 in Torrance, California. Its first commercial product was UNIAPT, released in 1969 as an early end-user computer-aided manufacturing system. In 1973, United Computing acquired the ADAM automated drafting and machining code from MGS. That technology became the basis for UNI-GRAPHICS, which was commercialized as Unigraphics in 1975. McDonnell Douglas acquired United Computing in 1976 and created CAD/CAM-oriented divisions, including the Unigraphics Group. The organization expanded in St. Louis and released Unigraphics in 1980 as a major three-dimensional modeling hardware and software offering. In 1991, EDS acquired the relevant McDonnell Douglas systems-integration operations. EDS initially used the EDS Unigraphics name and later established Unigraphics Solutions as a wholly owned subsidiary in 1997. The company went public during this period, although EDS continued to hold majority control. Unigraphics Solutions expanded through acquisitions, including Engineering Animation and Applicon, acquired in 1999. In 2001, the company adopted the UGS name. EDS later repurchased the remaining publicly held shares and acquired SDRC, a competing CAD and PLM provider. The two businesses were consolidated as EDS PLM Solutions, creating a broader product lifecycle management operation. EDS sold EDS PLM Solutions in 2004 to Bain Capital, Silver Lake Partners, and Warburg Pincus. The business again operated under the UGS name as an independent software company. Its portfolio combined CAD/CAM/CAE applications, PLM and collaboration tools, simulation, visualization, manufacturing planning, and engineering infrastructure technologies. The 2005 acquisition of Tecnomatix further strengthened its manufacturing software capabilities. Siemens AG announced the acquisition of UGS on January 24, 2007, for US$3.5 billion. Completion took place on May 7, 2007. UGS was placed within Siemens's Automation & Drives activities as the UGS PLM Software division and was later integrated into Siemens Digital Industries Software. The independent UGS corporate entity consequently became defunct, while key product technologies such as NX and Teamcenter continued under Siemens.
