RuleStream to Showcase Latest in Rules-driven Product Management Technology at SolidWorks World 2005

WAKEFIELD, Mass.--Jan. 1, 20059, 2005--RuleStream Corporation, provider of rules- driven product management (RPM) solutions to the discrete manufacturing industries, will demonstrate RuleStream's SolidWorks(R) integrated solution at the upcoming SolidWorks World 2005 conference.

RuleStream, a SolidWorks Solution Partner, will exhibit at booth #402 during the conference, scheduled from January 30 through February 2 at Disney's Coronado Springs Resort in Orlando, Florida.

Through its complete integration with SolidWorks 2005 software, RuleStream v5.6 ensures that automated product decisions reflect an engineer-to-order manufacturer's most up-to-date product-based intellectual property. It also allows design and manufacturing engineers to see the impact of configuration changes on the product design in real-time.

The RuleStream team will demonstrate the ease with which SolidWorks-based product design processes can be automated through RuleStream's innovative user environment, and how users of rules-based software can validate designs more effectively, increase opportunities to assess design alternatives and have time to invent new ideas. RuleStream will also highlight some of the benefits this innovative software offers, including custom order engineering productivity gains and increased engineering throughput.

Now in its seventh year, the SolidWorks International User Conference and Exposition brings together designers, engineers, managers and partners to discuss ideas, trends and the technology shaping the future of mechanical design.

"RuleStream's software has set a benchmark in automating design, quotation and manufacturing processes, enabling customers to respond to orders more rapidly, accurately and efficiently," said David Vredenburgh, chief executive officer of RuleStream. "Our latest developments offer even greater sales win rates, shorter lead times and more precise quotations. We look forward to demonstrating how this technology lowers costs through increased productivity, reduced engineering times and fewer errors."

"RuleStream's rules-driven product management approach is very complementary to our SolidWorks 2005 offering," said Brian Houle, manager of SolidWorks Partner Program. "RuleStream is a logical choice for customers looking to drive even more value from their SolidWorks software investment, as its automation capabilities can significantly reduce the time and effort that must go into custom product sales and engineering efforts. RuleStream's effective integration with the SolidWorks user environment and platform ensures that this will be the case for a long time to come."
