Modeling software using Eclipse plugin

I am brand new to modeling software (my greatest reference so far has been the Wikipedia page on UML). Are there any free tools that I can use with Eclipse to auto-generate diagrams?

Thanks

EDIT:Just to clarify, I am not necessaril开发者_Go百科y looking for the 'right' solution, as I don't have a specific problem. I am just trying to see what is out there that other people use!

EDIT: Tried eUML2 . Worked ok. It destroys the look of the code (if you have ever seen auto-generated HTML code or the code created by NetBeans, image that now) by adding comments everywhere. The background says evaluation in huge letters, which is also annoying. The UML is decent, but definitely not standard. All in all, not what i'm looking for. On to something else...

EDIT: Tried UMLet. Works well, very easy to get the hang of. Unfortunately it does not auto-pull any information from the source code. Will likely leave it installed for now

You may take a look at eUML. It creates nice looking UML diagrams. However, what I don't like with it is that it is very strictly connected to the source code and thus lacks some flexibility. Any change in the source code changes the diagrams and the other way around - and this is IMO not always desirable.

Check Eclipse MDT (Model Developing Tools)

You have plenty of UML tools with Galileo and will have UML tools for Helios in the next six months. I am a paid customer so got today the Helios UML build from Omondo.Please note that if you are not a paid up customer then you will not be able to download the lastest Helios build !!
