         AUTODESK FIRST QUARTER EARNINGS PER SHARE INCREASE 72 PERCENT;
               RAISES GUIDANCE FOR SECOND QUARTER AND FISCAL YEAR

    SAN RAFAEL, Calif., May 19 /PRNewswire-FirstCall/ -- Autodesk, Inc. (Nasdaq:
ADSK) today announced financial results for its first fiscal quarter ended April
30, 2005. For the first quarter, Autodesk reported net revenues of $355 million,
a 19 percent increase over $298 million reported in the first quarter of the
prior year.

    First quarter net income was $76 million, or $0.31 per diluted share, on a
GAAP basis and $75 million, or $0.30 per diluted share on a non-GAAP basis.
Non-GAAP net income excludes a $1 million benefit related to the successful
resolution of tax audits for a prior year. Net income in the first quarter of
the prior year was $43 million, or $0.18 per diluted share, on a GAAP basis, and
$51 million, or $0.22 per diluted share on a non-GAAP basis.

    "Autodesk had another outstanding quarter," said Carol Bartz, Autodesk
chairman and CEO. "In March, we launched the strongest product portfolio in the
company's history, which included more than 25 products. Our customers are
interested in quick implementation, ease of use and fast return on investment.
Our results demonstrate that Autodesk is meeting those needs."

    Autodesk's performance was driven by strong growth in revenues from new
seats and subscriptions, increasing penetration of its vertical and 3D products
and continued improvement in profitability.

    First quarter revenues from new seats increased 22 percent over the prior
year. Revenues from new seats of AutoCAD increased 26 percent over the prior
year.

    Combined revenues from subscriptions and upgrades increased 19 percent over
the first quarter of fiscal 2005. Consistent with company strategy, subscription
revenues, which are called maintenance in the financial statements, increased 57
percent over last year. Combined revenues from subscriptions and upgrades
continue to represent approximately one-third of total revenues.

    The company's vertical and 3D products continue to increase their market
penetration. In the first quarter, revenues from Autodesk Map(R) 3D increased 25
percent over the prior year. Combined revenues from AutoCAD(R) Mechanical and
AutoCAD(R) Electrical software increased 53 percent over last year. Revenues
from new commercial seats of Autodesk(R) Inventor(R) Series, Autodesk Inventor
Professional, Autodesk(R) Revit(R) Building, Autodesk AutoCAD(R) Revit(R)
Series, and Autodesk Civil 3D(TM) software, increased 83 percent over the prior
year.

    During the quarter Autodesk continued to improve its profitability.
Operating margins increased to 26 percent on a GAAP and non-GAAP basis.
Operating margins in the first quarter of fiscal 2005 were 18 percent on a GAAP
basis and 21 percent on a non-GAAP basis.

    "I have never been more confident of our future opportunities," said Bartz.
"We have already introduced outstanding new versions of our product portfolio.
Our refreshed product line and our commitment to continue to improve our
productivity and efficiency position the company for strong growth. We've got
the right strategy, the right products and the right people to continue to grow
this company faster and more profitably than our competitors."



    A reconciliation of the above non-GAAP operating margin, net income and EPS
amounts to the corresponding GAAP amounts is provided at the end of this press
release.

    Business Outlook
    The following statements are forward looking statements which are based on
current expectations and which involve risks and uncertainties some of which are
set forth below.

    Second Quarter Fiscal 2006
    Net revenues for the second quarter of fiscal 2006 are currently expected to
be in the range of $350 million to $360 million. Operating expenses are expected
to increase in the second quarter due to increasing investments in growth
initiatives. GAAP and non-GAAP earnings per diluted share are currently expected
to be in the range of $0.22 to $0.24 per diluted share.

    Full Year Fiscal 2006
    For fiscal year 2006, net revenues are currently expected to be in the range
of $1.45 billion to $1.5 billion. GAAP and non-GAAP earnings per diluted share
are expected to be in the range of $1.14 to $1.19.

    All fiscal 2006 EPS guidance ranges are based on the company's 20 percent
estimated tax rate. The company currently believes that its effective tax rate
will revert back to a 24 percent effective tax rate in fiscal year 2007.

and uncertainties, including statements in the paragraphs under "Business
Outlook" above, statements regarding our expected effective tax rate and other

opportunities, failure to successfully integrate new or acquired businesses and
technologies, failure to achieve sufficient sell-through in our channels for new
or existing products, failure of key new applications to achieve anticipated
levels of customer acceptance, pricing pressure, failure to achieve continued
cost reductions and productivity increases, failure to achieve continued
migration from 2D products to 3D products, unanticipated changes in tax rates,
failure to achieve continued success in technology advancements, changes in
foreign currency exchange rates, the financial and business condition of our
reseller and distribution channels, renegotiation or termination of royalty or
intellectual property arrangements, interruptions or terminations in the
business of the company's third party developers, failure to achieve continued
migration from 2D products to 3D products, failure to grow lifecycle management
or collaboration products, and unanticipated impact of accounting for technology
acquisitions.

To supplement our consolidated financial statements presented on a GAAP basis,
Autodesk uses non-GAAP measures of operating results, net income and net income
per share, which are adjusted to exclude certain costs, expenses, gains and
losses we believe appropriate to enhance an overall understanding of our past
financial performance and also our prospects for the future. These adjustments
to our GAAP results are made with the intent of providing both management and
investors a more complete understanding of Autodesk's underlying operational
results and trends and our marketplace performance. For example, the non-GAAP
results are an indication of our baseline performance before gains, losses or
other charges that are considered by management to be outside of our core
operating results. In addition, these adjusted non-GAAP results are among the
primary indicators management uses as a basis for our planning and forecasting
of future periods. The presentation of this additional information is not meant
to be considered in isolation or as a substitute for net income or diluted net
income per share prepared in accordance with generally accepted accounting
principles in the United States.

(1)  To supplement our consolidated financial statements presented on a GAAP
     basis, Autodesk uses non-GAAP measures of operating results, net income and
     net income per share, which are adjusted to exclude certain costs,
     expenses, gains and losses we believe appropriate to enhance an overall
     understanding of our past financial performance and also our prospects for
     the future. These adjustments to our GAAP results are made with the intent
     of providing both management and investors a more complete understanding of
     Autodesk's underlying operational results and trends and our marketplace
     performance. For example, the non-GAAP results are an indication of our
     baseline performance before gains, losses or other charges that are
     considered by management to be outside of our core operating results.

     In addition, these adjusted non-GAAP results are among the primary
     indicators management uses as a basis for our planning and forecasting of
     future periods. The presentation of this additional information is not
     meant to be considered in isolation or as a substitute for net income or
     diluted net income per share prepared in accordance with generally accepted
     accounting principles in the United States.

(1)  To supplement our consolidated financial statements presented on a GAAP
     basis, Autodesk uses non-GAAP measures of operating results, net income and
     net income per share, which are adjusted to exclude certain costs,
     expenses, gains and losses we believe appropriate to enhance an overall
     understanding of our past financial performance and also our prospects for
     the future. These adjustments to our GAAP results are made with the intent
     of providing both management and investors a more complete understanding of
     Autodesk's underlying operational results and trends and our marketplace
     performance. For example, the non-GAAP results are an indication of our
     baseline performance before gains, losses or other charges that are
     considered by management to be outside of our core operating results.

     In addition, these adjusted non-GAAP results are among the primary
     indicators management uses as a basis for our planning and forecasting of
     future periods. The presentation of this additional information is not
     meant to be considered in isolation or as a substitute for net income or
     diluted net income per share prepared in accordance with generally accepted
     accounting principles in the United States.

     split in the form of a stock dividend to stockholders of record as of

     consolidated fiscal year effective income tax rate declined from 24% to
     20%. For purposes of comparison, we have assumed the new estimated
     effective income tax rate of 20% in calculating our non-GAAP net income and
