Obviously if you are serious about UML in the long run you need to use a software UML tool like the ones suggested in the other answers, but I've found that a whiteboard is one of the best tools for UML diagramming, especially during the design phase, or when you are exploring different alternatives. Nothing beats a whiteboard for speed/flexibility in my mind. They are also great for collaboration assuming you are collocated physically.

For me it's Enterprise Architect from Sparx Systems. A very rounded UML tool for a very reasonable price. 

Very strong feature list including: integrated project management, baselining, export/import (including export to html), documentation generation from the model, various templates (Zachman, TOGAF, etc.), IDE plugins, code generation (with IDE plugins available for Visual Studio, Eclipse &amp; others), automation API - the list goes on. 

Oh yeah, don't forget support for source control directly from inside the tool (SVN, CVS, TFS &amp; SCC).

I would also stay away from Visio - you only get diagrams, not a model. Rename a class in one place in a UML modelling tool and you rename in all places. This is not the case in Visio!

blocks|key|702762|text|由于我通常更多地将UML用作一种通信工具，而不是建模工具，所以有时我需要稍微修改一下语言，这使得严格的建模工具相当笨拙。此外，他们往往有很大的开销，以偶尔绘制。这也意味着我不会给那些能很好地处理往返建模的工具任何加分。记住这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|702763|在使用Visio时，我倾向于使用these模板来满足我的UMLing需求(内置的很糟糕)。这可能是因为我已经习惯了它，因为它是我目前任务中的主要图表工具。|offset|length|702764|OmniGraffle也有一些内置的UML模板，在Graffletopia上有更多，但我不推荐它作为一个图表工具，因为它有太多的怪癖(怪癖，对许多事情都很好，但不适用于UML)。免费试用，所以一定要...:)|702765|我曾经尝试过MagicDraw，但虽然功能强大，但我发现它的用户界面让人分心。|702766|否则，我发现Topcased是一个有趣的项目(或一组项目)。上一次我使用它，它仍然有一些but，但它工作了，而且似乎从那以后发展得很好。在任何支持Eclipse的平台上都能很好地工作。自由，就像演讲和啤酒一样:)|702767|至于绘图工具Dia，它相当难看(界面和结果图)，但它确实完成了工作。另一个有趣的免费建模工具是Umbrello，但我并没有经常使用它。|702768|我绝对同意mashi的观点，即白板很棒(与数码相机或手机一起使用)。|702769|我使用过的一些最好的工具可能属于Rational系列工具。|702770|entityMap|0|LINK|mutability|MUTABLE|url|http://office.microsoft.com/visio|1|http://softwarestencils.com/uml/index.html|2|http://www.omnigroup.com/applications/OmniGraffle/pro/|3|http://graffletopia.com/categories/programming|4|http://magicdraw.com/|5|http://topcased.gforge.enseeiht.fr/|6|http://www.gnome.org/projects/dia/|7|http://uml.sourceforge.net/index.php|8|https://stackoverflow.com/questions/15376/whats-the-best-uml-diagramming-tool#24944|9|http://www-01.ibm.com/software/rational/sw-bycategory/subcategory/SW710.html^0|0|3|5|0|G|5|1|0|0|B|2|P|C|3|0|6|9|4|0|6|8|5|0|6|3|6|1B|8|7|0|5|5|8|0|G|8|9|0^^$0|@$1|2|3|4|5|6|7|1H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|1I|8|@]|9|@$D|1J|E|1K|1|1L]|$D|1M|E|1N|1|1O]]|A|$]]|$1|F|3|G|5|6|7|1P|8|@]|9|@$D|1Q|E|1R|1|1S]|$D|1T|E|1U|1|1V]]|A|$]]|$1|H|3|I|5|6|7|1W|8|@]|9|@$D|1X|E|1Y|1|1Z]]|A|$]]|$1|J|3|K|5|6|7|20|8|@]|9|@$D|21|E|22|1|23]]|A|$]]|$1|L|3|M|5|6|7|24|8|@]|9|@$D|25|E|26|1|27]|$D|28|E|29|1|2A]]|A|$]]|$1|N|3|O|5|6|7|2B|8|@]|9|@$D|2C|E|2D|1|2E]]|A|$]]|$1|P|3|Q|5|6|7|2F|8|@]|9|@$D|2G|E|2H|1|2I]]|A|$]]|$1|R|3|-4|5|6|7|2J|8|@]|9|@]|A|$]]]|S|$T|$5|U|V|W|A|$X|Y]]|Z|$5|U|V|W|A|$X|10]]|11|$5|U|V|W|A|$X|12]]|13|$5|U|V|W|A|$X|14]]|15|$5|U|V|W|A|$X|16]]|17|$5|U|V|W|A|$X|18]]|19|$5|U|V|W|A|$X|1A]]|1B|$5|U|V|W|A|$X|1C]]|1D|$5|U|V|W|A|$X|1E]]|1F|$5|U|V|W|A|$X|1G]]]]

As I usually use UML more as a communication tool rather than a modeling tool I sometimes have the need to flex the language a bit, which makes the strict modeling tools quite unwieldy. Also, they tend to have a large overhead for the occasional drawing. This also means I don't give tools that handle round-trip modeling well any bonus points. With this in mind... 

When using <a href="http://office.microsoft.com/visio" rel="nofollow noreferrer">Visio</a>, I tend to use <a href="http://softwarestencils.com/uml/index.html" rel="nofollow noreferrer">these</a> stencils for my UMLing needs (the built in kind of suck). It could be that I have grown used to it as it is the primary diagramming tool at my current assignment.

<a href="http://www.omnigroup.com/applications/OmniGraffle/pro/" rel="nofollow noreferrer">OmniGraffle</a> also has some UML stencils built in and more are available at <a href="http://graffletopia.com/categories/programming" rel="nofollow noreferrer">Graffletopia</a>, but I wouldn't recommend that as a diagramming tool as it has too many quirks (quirks that are good for many things, but not UML). Free trial though, so by all means... :)

I've been trying out <a href="http://magicdraw.com/" rel="nofollow noreferrer">MagicDraw</a> a bit, but while functional, I found the user interface distracting. 

Otherwise i find the <a href="http://topcased.gforge.enseeiht.fr/" rel="nofollow noreferrer">Topcased</a> an interesting project (or group of projects). Last I used it it still had some bugs, but it worked, and seems to have evolved nicely since. Works great on any Eclipse-enabled platform. Free as in speech and beer :)

As for the diagramming tool <a href="http://www.gnome.org/projects/dia/" rel="nofollow noreferrer">Dia</a>, it's quite ugly (interface and resulting drawings), but it does get the job done. An interesting modeling tool free alternative is <a href="http://uml.sourceforge.net/index.php" rel="nofollow noreferrer">Umbrello</a>, but I haven't really used it much.

I definitely agree with <a href="https://stackoverflow.com/questions/15376/whats-the-best-uml-diagramming-tool#24944">mashi</a> that whiteboards are great (together with a digital camera or cellphone).

Probably some of the nicest tools I've used belong to the <a href="http://www-01.ibm.com/software/rational/sw-bycategory/subcategory/SW710.html" rel="nofollow noreferrer">Rational</a> family of tools.

Rational and Together/J are best-of-breed products, but expensive.

In my experience, I've enjoyed Eclipse Omondo and Sparx Enterprise Architect. Omondo integrates nicely with Eclipse for code generation, and has a very intuitive feel. However, it is strongly tied to Java. Sparx is a good tool for the price point, but lacks the full range of UML 2.0 diagrams.

Do NOT bother with Poseidon. It is buggy, bloated, and unusuable for all intents and purposes.

Some context: Recently for graduate school I researched UML tools for usability and UML comprehension in general for an independent project. I also model/architect for a living.

The previous posts have too many answers and not enough questions. A common misunderstanding is that UML is about creating diagrams. Sure, diagrams are important, but really you are creating a model. Here are the questions that should be answered as each vendor product/solution does some things better than others. Note: The listed answers are my view as the best even if other products support a given feature or need.

<ul>
<li>Are you modeling or drawing? (Drawing - <a href="http://argouml.tigris.org/" rel="noreferrer">ArgoUML</a>, free implementations, and <a href="http://office.microsoft.com/visio/" rel="noreferrer">Visio</a>) </li>
<li>Will you be modeling in the future? (For basic modeling - Community editions of pay products) </li>
<li>Do you want to formalize your modeling through profiles or meta-models? OCL? (<a href="http://www.sparxsystems.com" rel="noreferrer">Sparx</a>, RSM, <a href="http://www.visual-paradigm.com/product/vpuml/" rel="noreferrer">Visual Paradigm</a>) </li>
<li>Are you concerned about model portability, XMI support? (<a href="http://www.genmymodel.com" rel="noreferrer">GenMyModel</a>, <a href="http://www.sparxsystems.com" rel="noreferrer">Sparx</a>, <a href="http://www.visual-paradigm.com/product/vpuml/" rel="noreferrer">Visual Paradigm</a>, <a href="http://www.altova.com/umodel.html" rel="noreferrer">Altova</a>) </li>
<li>Do you have an existing set of documents that you need to work with? (Depends on the documents) </li>
<li>Would you want to generate code stubs or full functioning code?(<a href="http://www.genmymodel.com" rel="noreferrer">GenMyModel</a>, <a href="http://www.visual-paradigm.com/product/vpuml/" rel="noreferrer">Visual Paradigm</a>, <a href="http://www.sparxsystems.com" rel="noreferrer">Sparx</a>, <a href="http://www.altova.com/umodel.html" rel="noreferrer">Altova</a>) </li>
<li>Do you need more mature processes such as use case management, pattern creation, asset creation, RUP integration, etc? (RSA/RSM/IBM Rational Products) </li>
</ul>

Detailed Examples: IBM Rational Software Architect did not implement UML 2.0 all the way when it comes to realizes type relationships when creating a UML profile, but Visual Paradigm and Sparx got it right. 
Ok, that was way too detailed, so a simpler example would be <a href="http://argouml.tigris.org/" rel="noreferrer">ArgoUML</a>, which has no code generation features and focuses on drawing more than the modeling aspect of UML. <a href="http://www.sparxsystems.com" rel="noreferrer">Sparx</a> and <a href="http://www.visual-paradigm.com/product/vpuml/" rel="noreferrer">Visual Paradigm</a> do UML really well and generate code well, however, hooking into project lifecycles and other process is where RSM/RSA is strong. 
Watch out for closed or product specific code generation processes or frameworks as you could end up stuck with that product.

This is a straight brain dump so a couple details may not be perfect, however, this should provide a general map to the questions and solutions to looking into.

<li>has rock solid C++, Java, PHP and others import support,</li>
<li>is multiplatform (Linux, Windows, other OSes),</li>
<li>has a great SVG export support, which is important, because viewing large graphs in vector format, which scales fast in e.g. Firefox, is very convenient (you can quickly switch between "birds eye" view and class detail view),</li>
<li>is full featured, impressively intensively developed (look at <a href="http://bouml.free.fr/historic.html" rel="nofollow noreferrer">development history</a>, it's hard to believe that such fast progress is possible).</li>

blocks|key|5156373|text|我只是在这里补充两点，但我发现ArgoUML非常有用。它需要一点时间来适应它，而且有一点but+(我最后检查它是在.29版本左右)，但一旦你习惯了它，它就会工作得很好。它可以处理所有类型的UML图，这就是我更喜欢它的原因。而且，它是由tigris开发的，也就是为Eclipse开发了一个SVN存储库插件subclipse的人。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5156374|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Just throwing in my two bits here, but I found ArgoUML to be very useful. It takes a little while to get used to it and its a bit buggy (last I checked it was in version .29 or so) but it works pretty well once you get used to it. It handles all types of UML diagrams, which is why I prefer it. Also, its made by tigris, the same people who made subclipse, an SVN repository plug-in for Eclipse.

If you want to model at diagram level and also have a clean metamodel the new Omondo build allows live synchronization between MOF and UML Diagrams.
Just amazing to see my diagram and the xmi live synchronized each time I change something in my diagram and the model is changed. What is most incredible is that the model is also the metamodel and the MOF because everything is lived synchronized. Very powerful new concept for my point of view.

I also like Java code annotation and JPA support in the class diagram and in the model. I don't know any other tool having these 2 incredible features !!

+1 for TopCoder UML Tool after I had tried most of other free tools. 
My reasons are: 

1) The tool can save UML diagrams in the human-readable format XMI, so the file can be fed to the version control system easily. 

2) Support of Undo/Redo (this is the reason I've discharged ArgoUML). 

3) The diagram is kept in one single file, and not linked tightly with "workspace" or "project". 

StarUML is also good, though is old. Unfortunatley it is not developed/maintained any longer.

blocks|key|5157580|text|在我的实践中，我使用Sequence+Diagram+Editor。它真的是一个非常快速和有用的工具。我不喜欢它的一个原因是它是商业产品，而不是免费的。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5157581|entityMap|0|LINK|mutability|MUTABLE|url|http://www.sequencediagrameditor.com/^0|A|N|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

In my practice i use <a href="http://www.sequencediagrameditor.com/" rel="nofollow">Sequence Diagram Editor</a>. it is really fast and helpful tool. the one thing i don't like about it is that it is commercial product, not free.

blocks|key|3746798|text|我建议使用Pacestar+UML+Diagrammer。它可以帮助你快速生成UML2.0的图表，，flexible和通常理解的符号。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|3746799|我在许多项目中使用了它，我非常满意。它也不使用太多的内存和空间，只有6Mo的硬盘。|3746800|我非常喜欢它的最大特点是我可以从编辑器中复制图表并将其粘贴到MS+Word中……所以当我需要编辑一个特定的图表时，我只需点击，它就会在编辑器中打开，关闭它，更新就已经在MS+Word文档中完成了。|3746801|entityMap|0|LINK|mutability|MUTABLE|url|http://www.pacestar.com/uml/index.html^0|1D|I|5|N|0|0|0|15|0|0|2Q|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@$9|U|A|V|1|W]]|E|$]]|$1|F|3|G|5|6|7|X|8|@$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|13|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]]]

I advice to use <a href="http://www.pacestar.com/uml/index.html" rel="nofollow">Pacestar UML Diagrammer</a>. It helps you generate UML 2.0 diagrams quickly, easily, flexible AND commonly understood notation.

I used it in many projects and I'm very satisfied. And too it doesn't use much of memory and space just 6 Mo of Hard Disk.

And the most feature that I like it very much is that I can copy diagrams from the editor and paste them in MS Word... so when I need to edit a specific diagram, just I click on and it will be opened in the editor and by closing it, the updates had been done in MS Word document.

I'm trying to choose a tool for creating UML diagrams of all flavours. Usability is a major criteria for me, but I'd still take more power with a steeper learning curve and be happy. Free (as in beer) would be nice, but I'd be willing to pay if the tool's worth it. What should I be using?

What's the best UML diagramming tool?

我正在尝试选择一种工具来创建各种风格的UML图。可用性是我的一个主要标准，但我仍然会在学习曲线更陡峭的情况下获得更多的权力，并感到快乐。免费(比如啤酒)会很好，但如果这个工具值得的话，我愿意付钱。我应该使用什么？
