Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates.

For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents.

| Basis of Presentation [Abstract] | |
| Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Autodesk, Inc. (“Autodesk” or the “Company”) as of April 30, 2012, and for the three months ended April 30, 2012, have been prepared in accordance with accounting principles generally accepted in the U.S. for interim financial information along with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission (“SEC”) Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles (“GAAP”) for annual financial statements. In management’s opinion, Autodesk has made all adjustments (consisting of normal, recurring and non-recurring adjustments) during the quarter that were considered necessary for the fair presentation of the financial position and operating results of the Company. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. In addition, the results of operations for the three months ended April 30, 2012 are not necessarily indicative of the results for the entire fiscal year ending January 31, 2013, or for any other period. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes, together with management’s discussion and analysis of financial position and results of operations contained in Autodesk’s Annual Report on Form 10-K for the fiscal year ended January 31, 2012, filed on March 15, 2012. |

| Recently Issued Accounting Standards [Abstract] | |
| DescriptionOfNewAccountingPronouncementsRecentlyAdoptedAndNotYetAdoptedTextBlock | Recently Issued Accounting Standards With the exception of those discussed below, there have been no recent changes in accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”) or adopted by the Company during the three months ended April 30, 2012, that are of significance, or potential significance, to the Company. Accounting Standards Adopted in the Three Months Ended April 30,2012 In September 2011, the FASB issued Accounting Standard Update (“ASU”) 2011-08 regarding Accounting Standards Codification (“ASC”) Topic 350 “Intangibles – Goodwill and Other.” This ASU allows for the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary. Autodesk adopted ASU 2011-08 effective February 1, 2012. The adoption of this ASU did not have a material impact on Autodesk's consolidated statements of financial position, results of operations or cash flows. In June 2011, the FASB issued ASU 2011-05 regarding ASC Topic 220 “Comprehensive Income.” This ASU eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity and requires the presentation of the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In December 2011, the FASB issued ASU 2011-12, an amendment to an existing accounting standard which defers the requirement to present components of reclassifications of other comprehensive income on the face of the income statement. Autodesk adopted ASU 2011-05 and ASU 2011-12 effective February 1, 2012. This accounting pronouncement impacted the presentation of other comprehensive income but did not impact Autodesk's consolidated financial position, results of operations or cash flow. In May 2011, FASB issued ASU 2011-04 regarding ASC Topic 820 “Fair Value Measurement.” This ASU amends the fair value measurement guidance and includes enhanced disclosure requirements primarily around Level 3 fair value measurements based on unobservable inputs. Autodesk adopted ASU 2011-4 effective February 1, 2012. The adoption of this ASU did not have a material impact on Autodesk's consolidated statements of financial position, results of operations or cash flows. |

| Risks and Uncertainties [Abstract] | |
| Concentration of Credit Risk | Concentration of Credit Risk Autodesk places its cash, cash equivalents and marketable securities in highly liquid instruments with, and in the custody of, diversified financial institutions globally with high credit ratings and limits the amounts invested with any one institution, type of security and issuer. Autodesk’s primary commercial banking relationship is with Citibank and its global affiliates (“Citibank”). Citicorp USA, Inc., an affiliate of Citibank, is one of the lead lenders and agent in the syndicate of Autodesk’s $400.0 million line of credit facility. It is Autodesk’s policy to limit the amounts invested with any one institution by type of security and issuer. Total sales to the distributor Tech Data Corporation, and its global affiliates (“Tech Data”), accounted for 22% of Autodesk’s total net revenue for the three months ended April 30, 2012, and 17% of Autodesk's total net revenue for the three months periods ended April 30, 2011. The majority of the net revenue from sales to Tech Data relates to Autodesk’s Platform Solutions and Emerging Business segment and is for sales made outside of the United States. In October 2011, Tech Data purchased certain assets of Mensch and Maschine Software (“MuM”), which has been a distributor of our products in Europe. The acquisition concentrates additional sales through Tech Data, which on a consolidated basis would have accounted for 23% of Autodesk’s total net revenue for the three months periods ended April 30, 2011, if the acquisition had taken place at the beginning of fiscal 2012. In addition, Tech Data accounted for 21% and 21% of trade accounts receivable at April 30, 2012 and January 31, 2012, respectively. |

| Financial Instruments and Hedging Activities | Financial Instruments The following tables summarize the Company's financial instruments' amortized cost, gross unrealized gains, gross unrealized losses, and fair value by significant investment category as of April 30, 2012 and January 31, 2012:
____________________
____________________
Autodesk classifies its marketable securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Marketable securities with remaining maturities of less than 12 months are classified as short-term and marketable securities with remaining maturities greater than 12 months are classified as long-term. Autodesk may sell certain of its marketable securities prior to their stated maturities for strategic purposes or in anticipation of credit deterioration. Autodesk applies fair value accounting for certain financial assets and liabilities, which consist of cash equivalents, marketable securities and other financial instruments, on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and (Level 3) unobservable inputs for which there is little or no market data, which require Autodesk to develop its own assumptions. When determining fair value, Autodesk uses observable market data and relies on unobservable inputs only when observable market data is not available. There have been no transfers between fair value measurement levels during the three months ended April 30, 2012. Autodesk's cash equivalents, marketable securities and financial instruments are primarily classified within Level 1 or Level 2 of the fair value hierarchy. Autodesk values its available for sale securities on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1) or inputs other than quoted prices that are observable either directly or indirectly in determining fair value (Level 2). Autodesk's Level 2 securities are valued primarily using observable inputs other than quoted prices in active markets for identical assets and liabilities. Autodesk's Level 3 securities consist of investments held in auction rate securities, convertible debt securities and derivative contracts which are valued using probability weighted discounted cash flow models and some of the inputs to the models are unobservable in the market. A reconciliation of the change in Autodesk’s Level 3 items for the three months ended April 30, 2012 was as follows:
The following table summarizes the estimated fair value of our “available-for-sale securities” classified by the contractual maturity date of the security:
As of April 30, 2012 and January 31, 2012, Autodesk did not have any securities in a continuous unrealized loss position for greater than twelve months. The sales or redemptions of “available-for-sale securities” in the three months periods ended April 30, 2012 and 2011 resulted in no gains or losses. Proceeds from the sale and maturity of marketable securities three months periods ended April 30, 2012 and 2011 were $177.3 million and $131.1 million, respectively. Derivative Financial Instruments Under its risk management strategy, Autodesk uses derivative instruments to manage its short-term exposures to fluctuations in foreign currency exchange rates which exist as part of ongoing business operations. Autodesk's general practice is to hedge a majority of transaction exposures denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars and Australian dollars. These instruments have maturities between one to twelve months in the future. Autodesk does not enter into derivative instrument transactions for trading or speculative purposes. The bank counterparties in all contracts expose Autodesk to credit-related losses in the event of their nonperformance. However, to mitigate that risk, Autodesk only contracts with counterparties who meet the Company's minimum requirements under its counterparty risk assessment process. Autodesk monitors ratings, credit spreads and potential downgrades on at least a quarterly basis. Based on Autodesk's on-going assessment of counterparty risk, the Company will adjust its exposure to various counterparties. Autodesk generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. However, Autodesk does not have any master netting arrangements in place with collateral features. Foreign currency contracts designated as cash flow hedges Autodesk utilizes foreign currency contracts to reduce the exchange rate impact on a portion of the net revenue or operating expense of certain anticipated transactions. These contracts are designated and documented as cash flow hedges. The effectiveness of the cash flow hedge contracts is assessed quarterly using regression analysis as well as other timing and probability criteria. To receive cash flow hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge and the hedges are expected to be highly effective in offsetting changes to future cash flows on hedged transactions. The gross gains and losses on these hedges are included in “Accumulated other comprehensive income (loss)” and are reclassified into earnings at the time the forecasted revenue or expense is recognized. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, Autodesk reclassifies the gain or loss on the related cash flow hedge from “Accumulated other comprehensive income (loss)” to “Interest and other income (expense), net” in the Company's Condensed Consolidated Financial Statements at that time. The net notional amount of these contracts are presented net settled and were $415.8 million at April 30, 2012 and $419.6 million at January 31, 2012. Outstanding contracts are recognized as either assets or liabilities on the balance sheet at fair value. The majority of the net gain of $5.8 million remaining in “Accumulated Other Comprehensive Income (Loss)” as of April 30, 2012 is expected to be recognized into earnings within the next twelve months. Derivatives not designated as hedging instruments Autodesk uses foreign currency contracts which are not designated as hedging instruments to reduce the exchange rate risk associated primarily with foreign currency denominated receivables and payables. These forward contracts are marked-to-market at the end of each fiscal quarter with gains and losses recognized as “Interest and other income (expense), net.” These derivative instruments do not subject the Company to material balance sheet risk due to exchange rate movements because gains and losses on these derivative instruments are intended to offset the gains or losses resulting from the settlement of the underlying foreign currency denominated receivables and payables. The net notional amounts of these foreign currency contracts are presented net settled and were $62.3 million at April 30, 2012 and $75.1 million at January 31, 2012. In addition to these foreign currency contracts, Autodesk holds derivative instruments issued by privately held companies, which are not designated as hedging instruments. These derivatives consist of certain conversion options on the convertible debt securities held by Autodesk and an option to acquire a privately held company. These derivatives are recorded at fair value as of each balance sheet date and are recorded in “Other assets.” Changes in the fair values of these instruments are recognized in income as “Interest and other income (expense), net.” Fair Value of Derivative Instruments: The fair value of derivative instruments in Autodesk’s Condensed Consolidated Balance Sheets were as follows as of April 30, 2012 and January 31, 2012:
The effects of derivatives designated as hedging instruments on Autodesk’s Condensed Consolidated Statements of Operations were as follows for the three months periods ended April 30, 2012 and 2011, respectively (amounts presented include any income tax effects):
The effects of derivatives not designated as hedging instruments on Autodesk’s Condensed Consolidated Statements of Operations were as follows for the three months periods ended April 30, 2012 and 2011, respectively (amounts presented include any income tax effects):

| Stock-based Compensation Expense | Stock-based Compensation Expense Stock Plans As of April 30, 2012, Autodesk maintained two active stock plans for the purpose of granting equity awards to employees and to non-employee members of Autodesk’s Board of Directors: the 2012 Employee Stock Plan (“2012 Employee Plan”), which is available only to employees, and the Autodesk 2012 Outside Directors’ Plan (“2012 Directors' Plan”), which is available only to non-employee directors. Additionally, there are eight expired or terminated plans with options outstanding. The exercise price of all stock options granted under these plans was equal to the fair market value of the stock on the grant date. The 2012 Employee Plan was approved by Autodesk's stockholders in January 2012. The 2012 Employee Plan reserves up to 21.2 million shares which includes 15.2 million shares reserved upon the effectiveness of the 2012 Employee Plan as well as up to 6.0 million shares forfeited under certain prior employee stock plans during the life of the 2012 Employee Plan. The 2012 Employee Plan permits the grant of stock options, restricted stock units and restricted stock awards. Each restricted stock unit or restricted stock award granted will be counted against the shares authorized for issuance under the 2012 Employee Plan as 1.79 shares. If a granted option, restricted stock unit or restricted stock award expires or becomes unexercisable for any reason, the unpurchased or forfeited shares that were granted may be returned to the 2012 Employee Plan and may become available for future grant under the 2012 Employee Plan. As of April 30, 2012, 2.6 million options or restricted stock units have been granted under the 2012 Employee Plan. Options and restricted stock units that were granted under the 2012 Stock Plan vest over periods ranging from immediately upon grant to over a three year period and options expire ten years from the date of grant. The 2012 Employee Plan will expire on June 30, 2022. At April 30, 2012, 13.9 million shares were available for future issuance under the 2012 Employee Plan. The 2012 Director's Plan was approved by Autodesk's stockholders in January 2012. The 2012 Directors' Plan permits the grant of stock options, restricted stock units and restricted stock awards to non-employee members of Autodesk’s Board of Directors. Each restricted stock unit or restricted stock award granted will be counted against the shares authorized for issuance under the 2012 Directors' Plan as 2.11 shares. As of April 30, 2012, no options or restricted stock have been granted under the 2012 Directors' Plan. The 2012 Directors' Plan reserved 2.6 million shares of Autodesk common stock. The 2012 Employee Plan will expire on June 30, 2022. At April 30, 2012, 2.6 million shares were available for future issuance under the 2012 Director's Plan. The following sections summarize activity under Autodesk’s stock plans. Stock Options: A summary of stock option activity for the three months ended April 30, 2012 is as follows:
_______________ (1) Options expected to vest reflect an estimated forfeiture rate. As of April 30, 2012, total compensation cost of $65.2 million related to non-vested options is expected to be recognized over a weighted average period of 1.8 years. The following table summarizes information about the pre-tax intrinsic value of options exercised, and the weighted average grant date fair value per share of options granted, during the three months ended April 30, 2012, and 2011.

The following table summarizes information about options outstanding and exercisable at April 30, 2012:
_______________
These options will expire if not exercised at specific dates ranging through April 2022. Restricted Stock: A summary of restricted stock unit and restricted stock award activity for the three months ended April 30, 2012 is as follows:
During the three months ended April 30, 2012, Autodesk granted 0.6 million restricted stock units. The restricted stock units vest over periods ranging from immediately upon grant to a pre-determined date that is typically within three years from the date of grant. Restricted stock units are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. The fair value of the restricted stock units is expensed ratably over the vesting period. Autodesk recorded stock-based compensation expense related to restricted stock units of $10.8 million during three months ended April 30, 2012. Autodesk recorded stock-based compensation related to restricted stock units of $5.3 million, during the three months ended April 30, 2011. As of April 30, 2012, total compensation cost not yet recognized of $57.4 million related to non-vested restricted stock units, is expected to be recognized over a weighted average period of 1.6 years. At April 30, 2012, the number of restricted stock units granted but unreleased was 2.5 million. During the three months ended April 30, 2012, Autodesk granted 0.5 million performance restricted stock units. Performance restricted stock units vest with the attainment of predetermined goals and requisite service periods. Performance stock units are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. The fair value of the performance restricted stock units is expensed using the accelerated attribution method over the vesting period. Autodesk recorded stock-based compensation expense related to performance restricted stock units of $1.2 million during three months ended April 30, 2012. Autodesk recorded no stock-based compensation related to performance restricted stock units during the three months ended April 30, 2011. As of April 30, 2012, total compensation cost not yet recognized of $12.4 million related to non-vested performance restricted stock units, is expected to be recognized over a weighted average period of 1.9 years. At April 30, 2012, the number of performance restricted stock units granted but unreleased was 0.5 million. During the three months ended April 30, 2012, Autodesk granted no restricted stock awards. Restricted stock awards are granted to non-employee directors and vest on the date of the next annual meeting. Restricted stock awards are considered outstanding at the time of grant, as the stock award holders are entitled to many of the rights of a stockholder, including voting rights. The fair value of the restricted stock awards is expensed ratably over the vesting period. Autodesk recorded stock-based compensation expense related to restricted stock awards of $0.1 million during the three months ended April 30, 2012. Autodesk recorded stock-based compensation expense related to restricted stock awards of $0.1 million during the three months ended April 30, 2011. As of April 30, 2012, total compensation cost not yet recognized of $0.1 million related to non-vested restricted stock awards, is expected to be recognized over a weighted average period of 0.1 years. At April 30, 2012, the number of restricted stock awards granted but unreleased was 13,500. 1998 Employee Qualified Stock Purchase Plan (“ESP Plan”) Under Autodesk’s ESP Plan, which was approved by stockholders in 1998, eligible employees may purchase shares of Autodesk’s common stock at their discretion using up to 15% of their eligible compensation subject to certain limitations, at not less than 85% of fair market value as defined in the ESP Plan. At April 30, 2012, a total of 32.9 million shares were available for future issuance. This amount automatically increases on the first trading day of each fiscal year by an amount equal to the lesser of 10.0 million shares or 2% of the total of (1) outstanding shares plus (2) any shares repurchased by Autodesk during the prior fiscal year. Under the ESP Plan, the Company issues shares on the first trading day following March 31 and September 30 of each fiscal year. The ESP Plan expires during fiscal 2018. Autodesk issued 1.6 million shares under the ESP Plan during the three months ended April 30, 2012, at average prices of $21.63. During the three months ended April 30, 2011, Autodesk issued 1.8 million shares under the ESP Plan, at average prices of $15.28 per share, respectively. The weighted average grant date fair value of awards granted under the ESP Plan during the three months ended April 30, 2012, calculated as of the award grant date using the Black-Scholes-Merton option pricing model, was $14.00 per share. The weighted average grant date fair value of awards granted under the ESP Plan during the three months ended April 30, 2011, calculated as of the award grant date using the Black-Scholes-Merton option pricing model, was $13.46 per share. Stock-based Compensation Expense The following table summarizes stock-based compensation expense for the three months ended April 30, 2012 and 2011, respectively, as follows:
Autodesk uses the Black-Scholes-Merton option-pricing model to estimate the fair value of stock-based awards based on the following assumptions:
Autodesk estimates expected volatility for stock-based awards based on the average of the following two measures. The first is a measure of historical volatility in the trading market for the Company’s common stock, and the second is the implied volatility of traded forward call options to purchase shares of the Company’s common stock. Autodesk estimates the expected life of stock-based awards using both exercise behavior and post-vesting termination behavior as well as consideration of outstanding options. Autodesk does not currently pay, and does not anticipate paying any cash dividends in the foreseeable future. Consequently, an expected dividend yield of zero is used in the Black-Scholes-Merton option pricing model. The risk-free interest rate used in the Black-Scholes-Merton option pricing model for stock-based awards is the historical yield on U.S. Treasury securities with equivalent remaining lives. Autodesk recognizes expense only for the stock-based awards that are ultimately expected to vest. Therefore, Autodesk has developed an estimate of the number of awards expected to cancel prior to vesting (“forfeiture rate”). The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all stock-based awards. The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates. |

| Income Taxes | Income Tax Autodesk’s effective tax rate was 19% and 18% during the three months ended April 30, 2012 and 2011, respectively. Autodesk’s effective tax rate increased during the three months ended April 30, 2012 as compared to the same period in the prior fiscal year primarily due to lower tax benefits in fiscal 2013 from foreign earnings taxed at lower rates, expiration of the federal research credit and increased non-deductible stock-based compensation expense, partially offset by discrete tax benefits from closure of statute of limitations during the first quarter of fiscal 2013. Excluding the impact of discrete tax benefits of $6.3 million primarily associated with tax benefits from stock-based compensation and closure of a foreign statute of limitations in the three months ended April 30, 2012, the effective tax rate for the three months ended April 30, 2012 was 26% and was lower than the Federal statutory tax rate of 35% primarily due to foreign income taxed at lower rates partially offset by the impact of non-deductible stock-based compensation expense. As of April 30, 2012, the Company had $203.2 million of gross unrecognized tax benefits, excluding interest, of which approximately $189.8 million represents the amount of unrecognized tax benefits that would impact the effective tax rate, if recognized. It is possible that the amount of unrecognized tax benefits will change in the next twelve months; however, an estimate of the range of the possible change cannot be made at this time. At April 30, 2012, Autodesk had net deferred tax assets of $168.0 million. The Company believes that it will generate sufficient future taxable income in appropriate tax jurisdictions to realize these assets. |

| Goodwill | Goodwill The change in the carrying amount of goodwill during the three months ended April 30, 2012, is as follows:
Goodwill consists of the excess of cost over the fair value of net assets acquired in business combinations. Autodesk assigns goodwill to the reportable segment associated with each business combination, and tests goodwill for impairment annually in its fourth fiscal quarter or more often if circumstances indicate a potential impairment. When assessing goodwill for impairment, Autodesk uses discounted cash flow models that include assumptions regarding reportable segments’ projected cash flows (“Income Approach”) and corroborates it with the estimated consideration that the Company would receive if there were to be a sale of the reporting segment (“Market Approach”). Variances in these assumptions could have a significant impact on Autodesk’s conclusion as to whether goodwill is impaired or the amount of any impairment charge. Impairment charges, if any, result from instances where the fair values of net assets associated with goodwill are less than their carrying values. The process of evaluating the potential impairment of goodwill is subjective and requires significant judgment at many points during the analysis. The value of Autodesk’s goodwill could also be impacted by future adverse changes such as: (i) declines in Autodesk’s actual financial results, (ii) a sustained decline in Autodesk’s market capitalization, (iii) significant slowdown in the worldwide economy or the industries Autodesk serves, or (iv) changes in Autodesk’s business strategy or internal financial results forecasts. A hypothetical 10% decrease in the fair value of any of Autodesk’s four reporting units would not have an impact on the carrying value, nor result in an impairment, of goodwill shown on Autodesk’s balance sheet as of April 30, 2012 for the respective reporting units. |

This credit agreement contains customary covenants that could restrict the imposition of liens on Autodesk’s assets, and restrict the Company’s ability to incur additional indebtedness or make dispositions of assets if Autodesk fails to maintain the financial covenants. The line of credit is syndicated with various financial institutions, including Citicorp USA, Inc., an affiliate of Citibank, which is one of the lead lenders and agent. At April 30, 2012, Autodesk had no outstanding borrowings on this line of credit. This facility expires in May 2016. |

| Commitments and Contingencies | Commitments and Contingencies Guarantees and Indemnifications In the normal course of business, Autodesk provides indemnifications of varying scopes, including limited product warranties and indemnification of customers against claims of intellectual property infringement made by third parties arising from the use of its products or services. Autodesk accrues for known indemnification issues if a loss is probable and can be reasonably estimated. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations. In connection with the purchase, sale or license of assets or businesses with third parties, Autodesk has entered into or assumed customary indemnification agreements related to the assets or businesses purchased, sold or licensed. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations. As permitted under Delaware law, Autodesk has agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at Autodesk’s request in such capacity. The maximum potential amount of future payments Autodesk could be required to make under these indemnification agreements is unlimited; however, Autodesk has directors’ and officers’ liability insurance coverage that is intended to reduce its financial exposure and may enable Autodesk to recover a portion of any future amounts paid. Autodesk believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal. Legal Proceedings Autodesk is involved in a variety of claims, suits, investigations and proceedings in the normal course of business activities including claims of alleged infringement of intellectual property rights, commercial, employment, piracy prosecution, business practices and other matters. In the Company’s opinion, resolution of pending matters is not expected to have a material adverse impact on its consolidated results of operations, cash flows or its financial position. Given the unpredictable nature of legal proceedings, there is a reasonable possibility that an unfavorable resolution of one or more such proceedings could in the future materially affect the Company’s results of operations, cash flows or financial position in a particular period, however, based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company’s financial statements, any such amount is either immaterial or it is not possible to provide an estimated amount of any such potential loss. |

| Common Stock Repurchase Program | Common Stock Repurchase Program Autodesk has a stock repurchase program that is used largely to help offset the dilution from the issuance of stock under the Company’s employee stock plans and for such other purposes as may be in the interests of Autodesk and its stockholders, and has the effect of returning excess cash generated from the Company’s business to stockholders. During the three months ended April 30, 2012, Autodesk repurchased and retired 2.5 million shares at an average repurchase price of $39.79 per share. Common stock and additional paid-in capital and retained earnings were reduced by $54.1 million and $45.1 million, respectively, during the three months ended April 30, 2012. At April 30, 2012, 12.2 million shares remained available for repurchase under repurchase plans approved by the Board of Directors. During the three months ended April 30, 2012, Autodesk repurchased its common stock through open market purchases. The number of shares acquired and the timing of the purchases are based on several factors, including general market conditions, the number of employee stock option exercises, stock issuance, the trading price of Autodesk common stock, cash on hand and available in the United States, and company defined trading windows. |

| Earnings Per Share [Text Block] | Net Income Per Share Basic net income per share is computed using the weighted average number of shares of common stock outstanding for the period, including restricted stock awards and excluding stock options and restricted stock units. Diluted net income per share is based upon the weighted average shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of stock options and restricted stock units under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net income per share amounts:
The computation of diluted net income per share does not include shares that are anti-dilutive under the treasury stock method because their exercise prices are higher than the average market value of Autodesk’s stock during the period. For the three months ended April 30, 2012 and 2011, 9.1 million and 6.7 million potentially anti-dilutive shares, respectively, were excluded from the computation of net income per share. |

| Segment Reporting Disclosure [Text Block] | Segments Autodesk reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company’s reportable segments. Autodesk has four reportable segments: Platform Solutions and Emerging Business (“PSEB”), Architecture, Engineering and Construction (“AEC”), Manufacturing (“MFG”) and Media and Entertainment (“M&E”). Autodesk has no material inter-segment revenue. The PSEB, AEC and MFG segments derive revenue from the sale of licenses for software products and services to customers who design, build, manage or own building, manufacturing and infrastructure projects. Our M&E segment derives revenue from the sale of products to creative professionals, post-production facilities and broadcasters for a variety of applications, including feature films, television programs, commercials, music and corporate videos, interactive game production, web design and interactive web streaming. PSEB includes Autodesk’s design product, AutoCAD. Autodesk’s AutoCAD product is a platform product that underpins the Company’s design product offerings for the industries it serves. For example, AEC and MFG offer tailored versions of AutoCAD software for the industries they serve. Autodesk’s AutoCAD product also provides a platform for Autodesk’s developer partners to build custom solutions for a range of diverse design-oriented markets. PSEB’s revenue primarily includes revenue from sales of licenses of Autodesk’s design products, AutoCAD and AutoCAD LT, as well as the Autodesk Design Suite and many other design products. AEC software products help to improve the way building, civil infrastructure, process plant and construction projects are designed, built and managed. A broad portfolio of solutions enables greater efficiency, accuracy and sustainability across the entire project lifecycle. Autodesk AEC solutions include advanced technology for building information modeling ("BIM"), AutoCAD-based design and documentation productivity software, sustainable design analysis applications, and collaborative project management solutions. BIM, an integrated process for building and infrastructure design, analysis, documentation and construction, uses consistent, coordination information to improve communication and collaboration between the extended project team. AEC provides a comprehensive portfolio of BIM solutions that help customers deliver projects faster and more economically, while minimizing environmental impact. AEC’s revenue primarily includes revenue from the sales of licenses of Autodesk Revit standalone, Autodesk Building Design Suite, AutoCAD Civil 3D, AutoCAD Architecture and AutoCAD Map 3D products. MFG provides the manufacturers in automotive and transportation, industrial machinery, consumer products and building products with comprehensive digital prototyping solutions that bring together design data from all phases of the product development process to develop a single digital model created in Autodesk Inventor software. Autodesk’s solutions for digital prototyping enable a broad group of manufacturers to realize benefits with minimal disruption to existing workflows. MFG’s revenue primarily includes revenue from the sales of licenses of Autodesk Inventor standalone, Autodesk Product Design Suite, AutoCAD Mechanical and Autodesk Moldflow products. M&E is comprised of two product groups: Animation, including design visualization, and Creative Finishing. Animation products, such as Autodesk 3ds Max, Autodesk Maya and the Autodesk Entertainment Creation Suite, provide tools for digital sculpting, modeling, animation, effects, rendering and compositing, for design visualization, visual effects and games production. Creative Finishing products provide editing, finishing and visual effects design and color grading. All of Autodesk’s reportable segments distribute their respective products primarily through authorized resellers and distributors and, to a lesser extent, through direct sales to end-users. The accounting policies of the reportable segments are the same as those described in Note 1, “Business and Summary of Significant Accounting Policies” of our 2012 Annual Report on Form 10-K. Autodesk evaluates each segment’s performance on the basis of gross profit. Autodesk currently does not separately accumulate and report asset information by segment, except for goodwill, which is disclosed in Note 8, “Goodwill.” Information concerning the operations of Autodesk’s reportable segments is as follows:

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).
