| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The following table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in this table. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Natixis Funds Complex. More information about these and other discounts is available from your financial professional and in the section “How Sales Charges Are Calculated” on page 16 of the Prospectus, in Appendix A to the Prospectus and on page 71 in the section “Reduced Sales Charges” of the Statement of Additional Information (“SAI”).

| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During its most recently ended fiscal year, the Fund’s portfolio turnover rate was 81% of the average value of its portfolio.

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | ||||||||
| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods (except where indicated). The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same except that the example is based on the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement assuming that such waiver and/or reimbursement will only be in place through the date noted above and on the Total Annual Fund Operating Expenses for the remaining periods. The example for Class C shares for the ten-year period reflects the conversion to Class A shares after eight years. The example does not take into account brokerage commissions and other fees to financial intermediaries that you may pay on your purchases and sales of shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

| Strategy [Heading] | rr_StrategyHeading | Investments, Risks and Performance Principal Investment Strategies | ||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in securities, including common stocks and preferred stocks, of real estate investment trusts (“REITs”) and/or real estate-related companies (e.g., real estate operating companies). REITs are generally dedicated to owning, and usually operating, income-producing real estate, or dedicated to financing real estate. The Fund primarily invests in equity REITs, which own or lease real estate and derive their income primarily from rental income. To qualify as a REIT, a company must distribute a significant percentage of its taxable income to shareholders in the form of dividends (at least 90% in the U.S.); this dividend payout ratio is higher than that of non-REIT companies. Real estate-related companies are those companies whose principal activity involves the development, ownership, construction, management or sale of real estate; companies with significant real estate holdings; and companies that provide products or services related to the real estate industry. The Fund intends to meet its investment goal by investing primarily in a portfolio of securities of REITs and real estate companies, including those that are primarily focused on income-producing commercial property and real estate development. Companies in the real estate industry, including REITs and real estate operating companies in which the Fund may invest may have relatively small market capitalizations. The Fund invests in securities of issuers located in no fewer than three regions, North America, Europe and Asia Pacific. Under normal circumstances, the Fund’s regional weightings will be +/- 10% of the regional weightings of the Fund’s benchmark, the FTSE EPRA Nareit Developed Index (Net). Although the Fund does not seek to track any particular index, the Fund will be diversified in terms of geographic and property type exposures, and the FTSE EPRA Nareit Developed Index (Net) may be used as a benchmark for the regional weighting of the Fund’s portfolio. The Fund may invest up to 10% of its assets in securities of companies located in emerging markets. For the purposes of determining whether a particular country is considered an emerging market, the Fund uses the designation set forth by the FTSE EPRA Nareit Emerging Index. The Fund follows a focused investment approach and typically holds 50 to 60 securities. AEW employs a value-oriented investment strategy designed to identify securities that are priced below what it believes is their intrinsic value. AEW believes that ultimately the performance of real estate equity securities is dependent upon the underlying real estate assets and company management, as well as the overall influence of capital markets. When selecting investments for the Fund, AEW generally considers the following factors that it believes help to identify those companies whose shares represent the greatest value and price appreciation potential: Valuation: AEW has developed a proprietary model to assess the relative value of each stock in the Fund’s investment universe. These estimates are formulated by the investment teams in each region based on a detailed analysis of historical trends and expectations for the future for each company’s financial statements. As a first step in its modeling process, AEW inputs projected financial information for each company. After completion of preliminary pro forma statements, the assumptions utilized to create the pro forma statements are generally discussed with representatives from each company. This model is designed to estimate what an issuer’s anticipated cash flows are worth to a stock investor (a capital markets value) and to a direct real estate investor (a real estate value). The capital markets value and real estate value incorporate factors that AEW believes influence the valuation of the cash flows by these different types of investors. These factors are the quantification of a broad array of subjective characteristics that AEW believes are important in the relative valuation process for both sectors and individual stocks. The model helps AEW to identify stocks that it believes trade at discounts to either or both of these model values relative to similar stocks. AEW will generally sell a security once it is considered overvalued or when AEW believes that there is greater relative value in other securities in the Fund’s investment universe. Price: AEW examines the historic pricing of each company in the Fund’s universe of potential investments. Those stocks that have underperformed in price, either in absolute terms or relative to the Fund’s investment universe in general, are typically of greater interest, provided AEW can identify and disagree with the sentiment that caused the underperformance. Catalysts: When evaluating a security, AEW also seeks to identify potential catalysts, such as changes in interest rates, regional and local economic conditions and other factors, that in its opinion, could cause the marketplace to re-value the security upwards in the near term. These catalysts can be macro-economic (e.g. interest rate expectations), market-driven or company-specific (e.g. a company’s development pipeline) in nature. ESG: AEW seeks to identify environmental, social, and governance (“ESG”) factors that it believes are most relevant to real estate investments in the Fund’s investable universe. ESG factors may include, among other things, the environmental performance of buildings, diversity, equity and inclusion policies, corporate giving, and Board diversity. AEW incorporates insights from fundamental research and company meetings alongside third party data and ESG data sourced directly from the issuer into a proprietary ESG risk score, which is an input into AEW’s securities valuation analysis. While AEW considers ESG factors in all buy and sell decisions for the Fund, the ESG profile of an investment will not be prioritized over other considerations in AEW’s investment selection process. The Fund may continue to invest in an issuer with a lower ESG score if AEW believes the investment’s valuation remains attractive as measured by other factors.

| Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The bar chart and table shown below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year-to-year and by showing how the Fund’s average annual returns for the one-year, five-year and ten-year periods compare to those of a broad-based securities market index that reflects the performance of the overall market applicable to the Fund and an additional index that represents the market sectors in which the Fund primarily invests. Performance for Class C shares includes the automatic conversion to Class A shares after eight years, where applicable. The Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available online at im.natixis.com and/or by calling the Fund toll-free at 800-225-5478. The chart does not reflect any sales charge that you may be required to pay when you buy or redeem the Fund’s shares. A sales charge will reduce your return. To the extent that a class of shares was subject to the waiver or reimbursement of certain expenses during a period, had such expenses not been waived or reimbursed during the period, total returns would have been lower.

| AEW Global Focused Real Estate Fund | Real Estate Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Real Estate Risk: Because the Fund concentrates its investments in REITs and the real estate industry, the Fund’s performance will be dependent in part on the performance of the real estate market and the real estate industry in general. Investments in the real estate industry, including REITs, are particularly sensitive to economic downturns and are sensitive to factors such as changes in real estate values, property taxes and tax laws, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use and rents and the management skill and creditworthiness of the issuer. Companies in the real estate industry also may be subject to liabilities under environmental and hazardous waste laws. In addition, the value of a REIT is affected by changes in the value of the properties owned by the REIT or mortgage loans held by the REIT. REITs are also subject to default and prepayment risk. Many REITs are highly leveraged, increasing their risk. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

| AEW Global Focused Real Estate Fund | Small and Mid Capitalization Companies Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Small- and Mid-Capitalization Companies Risk: Compared to large-capitalization companies, small- and mid-capitalization companies are more likely to have limited product lines, markets or financial resources. Stocks of these companies often trade less frequently and in limited volume and their prices may fluctuate more than stocks of large-capitalization companies. As a result, it may be relatively more difficult for the Fund to buy and sell securities of small- and mid-capitalization companies.
|
||||||||
| AEW Global Focused Real Estate Fund | Equity Securities Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Securities Risk: The value of the Fund’s investments in equity securities could be subject to unpredictable declines in the value of individual securities and periods of below-average performance in individual securities or in the equity market as a whole. Value stocks can perform differently from the market as a whole and from other types of stocks. Value stocks also present the risk that their lower valuations fairly reflect their business prospects and that investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds generally take precedence over the claims of those who own preferred stock or common stock. Securities of real estate-related companies and REITs in which the Fund may invest may be considered equity securities, thus subjecting the Fund to the risks of investing in equity securities generally.

| AEW Global Focused Real Estate Fund | Currency Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Currency Risk: Fluctuations in the exchange rates between different currencies may negatively affect an investment. The Fund may be subject to currency risk because it may invest in securities or other instruments denominated in, or that generate income denominated in, foreign currencies. The Fund may elect not to hedge currency risk, or may hedge such risk imperfectly, which may cause the Fund to incur losses that would not have been incurred had the risk been hedged.

| AEW Global Focused Real Estate Fund | Foreign Securities Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Securities Risk: Investments in foreign securities may be subject to greater political, economic, environmental, credit/counterparty and information risks. The Fund’s investments in foreign securities also are subject to foreign currency fluctuations and other foreign currency-related risks. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity.
|

| AEW Global Focused Real Estate Fund | Emerging Markets Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Emerging Markets Risk: In addition to the risks of investing in foreign investments generally, emerging markets investments are subject to greater risks arising from political or economic instability, war, nationalization or confiscatory taxation, currency exchange or repatriation restrictions, sanctions by other countries (such as the United States or the European Union), new or inconsistent government treatment of or restrictions on issuers and instruments, and an issuer’s unwillingness or inability to make dividend, principal or interest payments on its securities. Emerging markets companies may be smaller and have shorter operating histories than companies in developed markets.

| AEW Global Focused Real Estate Fund | Cybersecurity and Technology Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity and Technology Risk: The Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems, which are subject to a number of different threats and risks that could adversely affect the Fund and its shareholders. Cybersecurity and other operational and technology issues may result in financial losses to the Fund and its shareholders.
|
||||||||
| AEW Global Focused Real Estate Fund | Large Shareholder Transaction Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large Shareholder Transaction Risk: Ownership of shares of the Fund may be concentrated in one or a few large investors. Such investors may redeem shares in large quantities or on a frequent basis. In addition, a large number of shareholders collectively may purchase or redeem Fund shares in large amounts rapidly or unexpectedly (collectively, such transactions are referred to as “large shareholder transactions”). In the event of a large shareholder transaction, the Fund may be required to sell investments at unfavorable times or prices, which may increase realized capital gains, including short-term capital gains taxable as ordinary income for shareholders who hold Fund shares in a taxable account, may accelerate the realization of taxable income to shareholders, may increase transaction costs, and may otherwise negatively impact fund performance. The effects of taxable income and/or gains resulting from large shareholder transactions would particularly impact non-redeeming shareholders who do not hold their Fund shares in an IRA, 401(k) plan or other tax-advantaged plan. In addition, such transactions potentially limit the use of any capital loss carryforwards and certain other losses to offset future realized capital gains (if any). Such transactions may also increase the Fund’s expenses. A number of circumstances may cause the Fund to experience large redemptions, such as changes in the eligibility criteria for the Fund or share class of the Fund; liquidations, reorganizations, repositionings, or other announced Fund events; or changes in investment objectives, strategies, policies, risks, or investment personnel.
|
||||||||
| AEW Global Focused Real Estate Fund | Focused Investment Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Focused Investment Risk: Because the Fund may invest in a small number of industries or securities, it may have more risk because the impact of a single economic, political or regulatory occurrence may have a greater adverse impact on the Fund’s net asset value.
|
||||||||
| AEW Global Focused Real Estate Fund | Liquidity Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk: Liquidity risk is the risk that the Fund may be unable to find a buyer for its investments when it seeks to sell them or to receive the price it expects. Decreases in the number of financial institutions willing to make markets in the Fund’s investments or in their capacity or willingness to transact may increase the Fund’s exposure to this risk. Events that may lead to increased redemptions, such as market disruptions or increases in interest rates, may also negatively impact the liquidity of the Fund’s investments when it needs to dispose of them. Markets may become illiquid quickly. If the Fund is forced to sell its investments at an unfavorable time and/or under adverse conditions in order to meet redemption requests, such sales could negatively affect the Fund. During times of market turmoil, there may be no buyers or sellers for securities in certain asset classes and dealers may be unwilling or unable to make a market for certain securities. Liquidity issues may also make it difficult to value the Fund’s investments. The Fund may invest in liquid investments that become illiquid due to financial distress, or geopolitical events such as sanctions, trading halts or wars.

There is a possibility that one or all of the quantitative models may fail to identify profitable opportunities at any time. Furthermore, the models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial losses for the Fund. Models may be predictive in nature and such models may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in losses for the Fund.
