PARIS, July 10, 2007 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced that Brazilian aerospace company ELEB is expanding its DS CATIA and ENOVIA SmarTeam implementations to reduce product development time and improve quality. São Paulo-based reseller Tecmes is supporting ELEB’s expanded implementation of CATIA and ENOVIA SmarTeam.

The enlarged ENOVIA SmarTeam product data management repository will enable ELEB to share information created in DS’s CATIA 3D design authoring solution without toggling through multiple systems to find the correct files or current versions. In addition to the expanded ENOVIA SmarTeam implementation, additional CATIA seats will allow ELEB to accommodate a steadily growing stream of business from aerospace companies in Latin America, North America, Europe and Asia.

“As our business grows, we must be able to respond quickly to our customers’ demands because they are also under market pressure to roll out new products quickly,” said Roberto Paiva, ELEB’s strategic planning manager. “Having all of our CATIA product data in a single, universally accessible ENOVIA SmarTeam repository will give us the agility we need across all of our departments to meet their needs.”

ELEB supplies landing gear systems and other critical components to aerospace companies in the US, Europe, Asia and Brazil. Its largest customer is Brazilian aerospace giant Embraer, the world’s third-largest commercial airplane maker.

“Market demands for speed, quality and agility are reaching all the way down the supply chain to small and medium-sized businesses, such as ELEB,” said Marcelo Lemos, general manager, Latin America, Dassault Systèmes. “CATIA and ENOVIA SmarTeam offer them the right-sized PLM solution to meet their customers’ needs without burdening them with unnecessary cost and complexity.”
