Paris, France, June 6, 2006  - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions announces, in the lead up to its annual CAA V5 DEVCON Conference in Paris on June 27-28, that its software partners, as valuable members of the worldwide DS ecosystem, are continuously contributing products which enhance and complete DS’ brand offerings. These products and solutions enable companies to go to market more quickly with reliable and innovative products, and allow customers to optimize processes, improve efficiency and maintain a competitive edge, irrespective of target market, while reducing the cost of ownership.

“Our CAAV5 partners’ products are seamlessly embedded within our solutions, improving productivity by optimizing processes essential to customers,” noted Pascal Daloz, VP Research & Development, Strategy & Business Development, Dassault Systèmes. “The common infrastructure of DS’ CAA V5 platform empowers partners to build innovative solutions that respond to customers’ current and future market challenges.”

A prime example is CATIA Composites Design, an advanced process-centric solution for customers in the aerospace, automotive, shipbuilding and consumer goods industries, which reduces design time, even for the most complex composite parts. DS’ market-leading partners Airbus CIMPA, Magestic Systems Inc., ESI Group and MTorres provide CAA based products to enhance their contributions towards developing composites-based next-generation aircraft. Combined solutions deliver a complete V5 offering for composites manufacturing techniques. Integration of Composites Design with production systems ensures that companies can benefit, regardless of the manufacturing process or the machine provider: www.3ds.com/flashgallery/end-to-end-composites-solution

DS’ CAA V5 partners contribute significantly to the electronics and high-tech consumer goods industries. Companies in these markets need to integrate electrical design data, such as wiring diagrams and schematics information into their design processes. ECAD Integration Suite from Productivity Engineering GmbH (PE), enables companies to optimize the printed circuit board development process and facilitates collaboration across the supply chain. Companies producing electronic devices also need to predict cooling airflow distribution and temperature levels which are critical for product reliability. Working hand-in-hand with DS, Fluent provides a solution to model heating and cooling patterns, allowing companies to optimize design for electronic products where overheating can create serious consumer issues.

The result is one of the largest and most vibrant PLM development communities. A total of over 150 partners have joined the program with some 5,000 developers working on the CAA V5 open software platform, and bringing to market more than 400 innovative products. This network of partnerships has transformed into a dynamic, open ecosystem, fostering a constant flow of ideas, applications, Industry Solutions and best practices among its members.

See the DS ecosystem in action at the annual CAA V5 DEVCON Conference in Paris on June 27-28, 2006 where customers and partners can network and learn the latest information on the CAA V5 development platform for PLM solutions.
