MCAE INTRODUCES FIRST WINDOWS-BASED FEA SOFTWARE WITH AUTOMATIC MESHING FOR
SOLID MODELS

(Indianapolis, Indiana -- November 14, 1994) Modern Computer Aided
Engineering (MCAE), Inc. today released Inertia Version 5, the first FEA
software running under Windows that can instantly analyze solid models. By
incorporating a new solids topology manager, Inertia Version 5 gains the
ability to import a solid model from a CAD system and automatically create
a mesh, sparing users the long hours of manually connecting lines to make
sure edges match. This version of Inertia also features enhanced
visualization tools such as hardware-implemented shading, rendering,
rotation, pan, and zoom.

For the growing number of CAD users who work with solid models, Inertia
Version 5 is a significant enhancement to an FEA package already known for
ease of use. Prior to this release, a solid model was transferred to
Inertia or any other PC-based analysis system as a collection of curves
and surfaces. Before the analysis could begin, the user had to connect the
curves manually to create congruent surfaces. With Inertia Version 5, this
is now done automatically by the software. New technology recognizes the
solid model's topology, giving the software the ability to perform fully
automated solids and surface meshing. Users simply import the solid, give
the command to create the mesh and it's done--no human involvement is
required. Currently this capability is available on UNIX and will soon be
available for Macintosh and PC/Windows platforms.

Inertia Version 5 features direct translation of solid models created with
Computervision's CADDS4, CADDS5 using CV-DORS, and Parametric Technology
Corp.'s Pro/Engineer. The software can also import solid models in the
IGES Solids format for compatibility with nearly all solid modeling
systems in use today.

The enhanced visualization capabilities in Inertia Version 5 give users the
ability to understand and present their work more effectively than ever.
New shading and rendering tools, implemented in hardware for fast
response, enhance the understanding of a model during the conceptual
design process and improve the quality of presentations. When these tools
are used in combination with the software's new hardware-implemented
rotate, zoom, and pan functions, the result is a powerful 3D visualization
system. Because users can view shaded, rendered solid models from a
variety of angles and rotate them very quickly, Inertia Version 5 provides
an effective on-screen visualization tool that can reduce the need for
physical prototypes.

The Inertia engineering system is designed specifically to bring advanced
computerized mechanical engineering techniques to the general purpose
user. It takes advantage of the pioneering efforts in the Macintosh and
Microsoft Windows environments such as non-hierarchical pop-up menu
structures, dialog boxes, and icons to simplify the user interface. The
Inertia engineering system supports all major graphic operating
environments including Microsoft Windows 3.1, Open Systems Foundation's
MOTIF, Sun's Open Look, and Apple Macintosh. The program runs identically
with a single user manual on all of these platforms and can share data
between them when they are linked on a network.

Inertia Version 5 sells for between $5,000-$15,000 and will be available
December 1, 1994. For more information, contact MCAE, Inc., 8425 Woodfield
