ANN ARBOR, Michigan, May 12, 2004 — CIMdata recently named UGS PLM Solutions, IBM/Dassault Systẻmes, CNC Software, and SolidCAM as the 2003 worldwide CAM software market leaders. Each was a leader in a different ranking used by CIMdata to position NC software vendors. UGS PLM Solutions was identified as being the largest CAM software supplier on the basis of the dollar volume of NC software and services revenues received by a vendor. IBM/Dassault Systẻmes (IBM/DS), however, is the largest vendor on the basis of end user payments for NC software and services. This grouping not only includes the revenues received by the vendor, but also the revenues retained by business partners or resellers. CNC Software continues to be the market leader on the basis of number of software seats sold and installed in industrial markets. This ranking measures the pervasiveness of the product. SolidCAM, an Israeli firm, was named as the most rapidly growing vendor among the significant NC software suppliers.
