Spatial Inc. Announces ACIS 5.2

2 July 1999

Spatial Inc. Announces ACIS 5.2; Version 5.2 Provides Stylized Multi-Surface Deformations and Improved Application Interface Tools

    BOULDER, Colo.--July 2, 1999--Spatial Inc. (AMEX: STY), the world's leading software developer of open, component 3D modeling technology and interoperability solutions, announces version 5.2 of ACIS(R) 3D Toolkit, the de facto standard 3D modeling kernel. This release delivers technology improvements to the core ACIS modeling kernel as well as advancements to Spatial's Deformable Modeler and interoperability products. With this line-up of new functionality and enhancements, Spatial continues to provide the over 500 ACIS licensees with the most progressive technology available at an industry-leading pace.
    ACIS 5.2 builds on the success of ACIS 5.0 and 5.1, with enhancements that include real-time multiple-surface sculpting, interactive bending, twisting and stretching of solids, improved blending interface, a new memory management component, and support for Red Hat(R) Software, Inc.'s Linux(TM).
    "Our goal is to deliver the best-in-class geometric modeling and interoperability toolkit to our customers. The technology advances in the ACIS 5.2 release will bring improvements to all phases of mechanical engineering, from design, to analysis, to manufacturing." commented Phil Spreier, ACIS product marketing manager, Spatial. "We are particularly excited about the multi-surface sculpting capabilities in our deformable modeling technology. Designers can now sculpt solid models with an intuitive user interface, similar to sculpting with clay."

    ACIS 5.2 Features 

--   Multi-surface deformation technology, part of the ACIS Deformable
     Modeling Husk, allows users to sculpt a network of surfaces as
     though they were one.

--   New memory management component that enables application
     developers to easily customize and control how ACIS allocates and
     de-allocates memory.

--   Completion of an intelligent, easy to use interface for advanced
     blending functionality.

--   Integration of IGES technology obtained through the InterData
     Access Inc. acquisition.

--   Improvements to trim back swept surfaces from self-intersections.

--   Reduced memory usage in history and roll back management.

--   Expanded Feature Naming support, to include skinning and lofting.

--   Introduction of optimized periodic face splitting algorithm. This
     new algorithm intelligently splits periodic faces to maximize
     face size, reducing the creation of small silver faces, which can
     cause problems with meshing and analysis algorithms.

--   Performance improvements to local operations to increase the
     speed of sheet thickening.

--   Support for Red Hat Software, Inc.'s Linux operating system.

--   Over 300 user requested enhancements
