EXHIBIT A

IDENTITY AND ITEM 3 CLASSIFICATION OF A SUBSIDIARY OF
PARENT HOLDING COMPANIES

     This Schedule 13G is being filed by Twentieth Century
Companies, Inc. ("TCC").  Investors Research Corporation ("IRC"),
an investment advisor registered under Section 203 of the
Investment Advisors Act of 1940, is a wholly-owned subsidiary of
TCC.  Mr. James E. Stowers, Jr., controls TCC by virtue of his
beneficial ownership of a majority of the voting stock of TCC.

     As a result of its status as investment advisor to six investment companies
registered under Section 8 of the Investment Company Act and to several
institutional investors, IRC is deemed to be the beneficial owner of and has the
sole authority to dispose of and vote certain shares (the "Shares") of the
outstanding common stock of Autodesk Inc. (the "Issuer").

     TCC, as a result of its control of IRC, and Mr. Stowers, as a result of his
control of TCC, are also deemed to beneficially own all such shares deemed to be
beneficially owned by IRC. Mr. Stowers, TCC and IRC all disclaim beneficial
ownership of the Shares.

     The ownership of one investment company client of IRC, Twentieth Century
Investors, Inc. ("TCI"), formerly totalled more than 5% of a class of securities
of the Issuer.

     This Schedule 13G is being filed by TCC on behalf of TCC,
IRC, TCI and Mr. Stowers.
