June 9, 1999: Unigraphics and Heide Corporation sign licensing agreement

       Leading-Edge KBE Software Will be Incorporated Into Unigraphics

    ST. LOUIS, Aug. 9 /PRNewswire/ -- Unigraphics Solutions Inc. (NYSE: UGS)
and Heide Corporation today have announced a partnership which will accelerate
the delivery of knowledge enabled applications within Unigraphics.  Under this
partnership, Unigraphics Solutions -- in cooperation with Heide consultants --
will incorporate Heide Corporation's Intent!(TM) language as the core
technology for rules based engineering.  In addition, Heide Corporation will
further strengthen its leading-edge software by adopting the industry standard
Parasolid geometric kernel for Intent!
    Intent! is a toolkit for building engineering automation solutions.  It is
a rule-based design system that allows capturing and reuse of engineering
design rules, and a configuration system for selecting and assembling
compatible parts.  It is extensible, in that users may define flexible "smart
parts" that can be assembled and configured in ways that are not
pre-programmed but which conform to engineering, configuration and geometric
rules.
    "The move to incorporate Intent! into Unigraphics is an exciting element
of our strategy to provide knowledge enriched applications," says Chuck
Grindstaff, director of the Unigraphics line of business for Unigraphics
Solutions.  "Today, Unigraphics customers can encode systems engineering
knowledge in tools like WAVE and leverage process specific knowledge with
tools like MoldWizard.  The addition of Heide's Intent! will provide further
value to Unigraphics customer by enabling them to encode engineering know-how
into the very early stages of the product development process."
    "Collaborating with Unigraphics Solutions will result in the best in class
solution for Knowledge Enabled Mechanical CAD," says Scott Heide, president of
Heide Corporation.  "Use of the Intent! product has resulted in substantial
improvements to the engineering throughput of companies like GM, GE and
Hamilton Standard and we are confident that Unigraphics customers will find
even more benefit from the integrated solution.  Furthermore, the adoption of
the Parasolid Kernel will enable Heide Corporation to provide advanced
applications (such as sales configurators) to the rapidly growing Parasolid
market."
    "The Intent! language is simply the best rules based engineering tool on
the market," says Gary Newell, chief architect for Unigraphics.  "In addition,
the domain experience of Heide's consulting team will greatly accelerate our
deployment of knowledge enriched applications."
