UML tool - one big diagram

Hi,

I started working on some big Eclipse plugin project and I am supposed to create a diagram that will show haow everything is built for new programmers that will join our team. I need a UML tool that will be able to create one big class diagram out of the whole plugin. The problem is that if I use full classes on the diagram is just to big, with methods and attributes taking up too much space and making it hard to read. And when I use only class frames, every dependency but interface implementation disappear. Anyone knows a tool that can do that automatically or fairly easily in one diagram? I tried already: StarUML, ArgoUML, Violet, Enterprise Architect, Visual Paradigm, UML2 Eclipse plugin, which refuses to collaborate at all and now I am battling with Poseidon evaluation version ...

I will be grateful for any suggestions

If this subject has been brought up, I appologize, but I could not find one that answers my question.

thanks,
Kate

Try to hide attribute compartment and operation compartment in class diagram, consult your product manuals.
