Editors to draw diagrams in Unified Modeling Language?

I was wondering how you draw diagrams in Unified Modeling Lang开发者_JAVA技巧uage for your project design? By hand on paper or some editors on computer? It will be great if there are some convenient editors or other gadgets for help. I am programming under Windows and Ubuntu.

Thanks and regards!

I used Sparx Enterprise Architect.

I reverse the java project and then just drag and drop from the Package Explorer to the diagram. When I have finished to present the existing classes I then add UML classes in the diagram. No code generation or model driven, just UML graphical representation mixing existing classes and abstract classes. I give my diagrams to the team and let them integrate it.

I am very lazy when modeling :-)

I can see my classes and navigate from one package to another showing associations, inheritances and dependencies dynamically. No need to create a diagram per view, I prefer to use the show hide links and directly navigate in the java code and model from the same diagram it is easier and a lot more powerful because interactive.

Just using the class contextual menu I can navigate. Really cool

I used Poseidon for UML for quite a while.. not that bad, it's just a little bit slow since it's written in Java.

If I remember correctly it also has a community license that can be obtained for free..

I would vote for StarUML maybe its not brand new, but it does the job!

It works under Windows.

I use Dia for my diagramming needs. It's open source and cross platform so you can switch between OS's without worrying about which format your diagrams were in. It exports to several different image types and has a Portable version (for Windows) as well.
