    I-DEAS(R) Freeform enhances product lifecycle processes for better
    quality, faster time-to-market

    SDRC today announced at the Atlantic Design & Manufacturing Show in New York, NY, I-DEAS(R) Freeform, an integrated, process oriented free-form modeling solution that efficiently links the physical and virtual worlds of complex free-form design, manufacturing and inspection tasks. This release of I-DEAS Freeform, formerly known as Imageware products, will be incorporated into the award-winning mechanical design automation suite, I-DEAS(R).
    "I-DEAS Freeform has been key in enabling us to extend our reach beyond 3D solid modeling and look at high-end freeform modeling in a new perspective," said David Narajowski, partner, Modaliti Design. "We have leveraged the additional I-DEAS Freeform capabilities to extend our open part modeling process, direct surface manipulation and real-time feedback; providing us with the necessary functionality to produce quality products with superb time-to-market availability."
    "We are pleased with the significant progress we have made in the promise of an integrated solution," said Glenn Wienkoop, president and COO, SDRC. "The integration of Freeform functionality into the I-DEAS product line is critical to providing our customers with a complete product authoring solution. We believe that continued investment in our Freeform technology will further enhance our customers' product lifecycle processes, leading to better quality products and faster time-to-market."
    I-DEAS Freeform components include:

    -- I-DEAS Freeform Modeler
    Provides a flexible environment utilized by artists, designers
    and engineers for free-form product design, rapid surfacing,
    high-quality surfacing, reverse engineering, computer aided
    verification, polygonal modeling, rapid prototyping, Class A
    surfacing and surface healing.

    -- I-DEAS Freeform Inspection
    A sub-set of I-DEAS Freeform Modeler, Inspection is a
    versatile and comprehensive part inspection solution for
    complete, accurate and rapid inspection of CAD to part or CAD
    to tool comparison.

    -- I-DEAS Freeform Light
    Addresses entry-level reverse engineering and basic rapid
    modeling, modification and exploration needs for capturing
    design intent.

    Notable I-DEAS Freeform user-driven enhancements include:

    -- Icon layout and menu structure consistent with I-DEAS
    Redesigned icons complement the look and feel of the newly
    announced I-DEAS user interface, while the consistent color
    scheme, styling, and graphics used makes the icons quickly
    recognizable by all users. The addition of a more intuitive
    menu system further extends the ease of use for the Freeform
    products.

    -- New 3D constraint engine
    The addition of a 3D constraint solver for curve networks
    together with fully associative surfacing tools, such as sweep
    and fillet, allows a massive acceleration in productivity when
    creating freeform models, from Class A automotive to
    feasibility design studies.

    -- Extended functionality for curve-based surface development
    The addition of many exciting new commands together with
    significant additions to existing functions for creating and
    manipulating curves and surfaces supports the curve based
    workflow of Class A surfacing users.
