Autodesk Inventor Continues to be the World's Fastest-Growing and Best Selling
                       3D Mechanical Design Application

AUTODESK UNIVERSITY, ORLANDO, Fla., Nov. 29 /PRNewswire-FirstCall/ -- Engineering teams and product designers are adopting Autodesk Inventor software, the fastest-growing and best selling 3D mechanical design application in the world, in record numbers. Autodesk, Inc. (Nasdaq: ADSK) today announced that it has sold over 500,000 seats of Autodesk Inventor, continuing to exceed that of all competing 3D design software applications. A rising number of mechanical engineers and product designers have selected Autodesk Inventor as their software platform of choice for realizing ideas. Using the integrated 2D drawing with 3D modeling capabilities in the Autodesk Inventor application makes it easier than ever before for engineers to leverage their years of expertise with AutoCAD while taking advantage of the superior 3D modeling and functional design capabilities found only in Autodesk Inventor.

"Our research shows that as more manufacturers make 3D modeling a priority in their product development initiatives, they are growing increasingly savvy about choosing tools," said Gisela Wilson, director at IDC Research. "They're looking to take advantage of 3D without sacrificing years of engineering expertise captured in 2D drawings -- and we believe that's driving growth in Autodesk Inventor use."

A September 2005 study by Wohlers Associates, Inc., in partnership with Cyon Research found that the mechanical CAD and product lifecycle management market grew to nearly $4 billion in 2004, with Autodesk Inventor leading the way in commercial mechanical design seats.

"Achieving the milestone of 500,000 seats is further validation of the Autodesk Inventor market leading status. The product's unmatched functionality continues to outclass competitive solutions," said Robert Kross, vice president, Autodesk Manufacturing Solutions Division. "From designing cars for manufacture in China to watches in Europe, engineering teams around the world are using Autodesk Inventor to communicate design information seamlessly so that their organizations can respond quickly and cost-effectively to changes in consumer demand."

There are many reasons why Autodesk Inventor continues to be the best selling 3D design software:

    -- It is the best choice for AutoCAD users because it is designed to make
       use of both 2D drawings and 3D modeling capabilities in an easy and
       intuitive design environment
    -- Offers unparalleled integrity and compatibility between 2D AutoCAD DWG
       files and 3D Autodesk Inventor models
    -- Provides leading-edge functional design capabilities, enabling
       mechanical engineers to focus on designing functionally rather than by
       geometric parameters
    -- Delivers built-in, easy to implement data management tools
    -- Institutes disciplined methods for sharing design data across the
       engineering workgroup and to users beyond the design team

"Autodesk Inventor enables us to create products more quickly, make changes more readily, and document them instantly," says Pat Leonhardt, product development manager for EASI. "As we continue to branch out into new product lines, Autodesk Inventor will be instrumental to our business as it definitely gives us an edge in a competitive environment."
