Can anyone recommend one ? I dont have much experience there, but since I think that it's pretty much more efficient to do those class graphs with such a nice editor instead of tons of rubbers, a pencil and paper, i'm searching a nice UML editor ?
I've tried few UML freeware (& shareware), and they suck!
The best of all I know, is "Rationnal Rose", a professionnal software, and the licence is too expensive for you (about 10 000€ ??? > )
