Description: MCA was used by I-DEAS Web Access, a program that was merged with Unigraphs to from Unigraphs NX, now known as NX.

History: I-DEAS Web Access was announced in 1999 by SDRC with the foal of providing web-based collaboration and visualization for use with I-DEAS software. SDRC was bought by Electronic Data System (EDS) in 2001. EDS also acquired UGS Corp, the makers of Unigraphs. EDS merged both I-DEAS and Unigraphs into one product, NX. In 2007, UGS was bought by Siemens AG who renamed the company to Siemens PLM Software.

I-DEAS Web Access files are no longer used, as the program was merged into NX in 2001 and Siemens has since been directing people away from the format [1], but some programs are still able to read the files, for example [2], [3], and [4].
