I-DEAS (Integrated Design and Engineering Analysis Software), a Computer-aided design software package. It was originally produced by Structural Dynamics Research Corporation in 1982.[1] I-DEAS was used primarily in the automotive industry,[1] most notably by Ford Motor Company (who standardized on the program[2]) and by General Motors.[1] SDRC was bought in 2001 by its competitor, Electronic Data Systems, which had also acquired UGS Corp. (maker of Unigraphics).[1] EDS merged these two products into NX.[3] UGS was purchased by Siemens AG in May 2007, and was renamed Siemens PLM Software.
