Hello Fenglei, If you will permit me, may I suggest another approach.
I have lurked, off and on, on this forum for quite a while. Rose has received great volleys of criticism about the lack of a decent layout algorithm. While technically true (the layout algorithm is rubbish), they miss the point. Rose, as a design tool, allows you to think and communicate. When you design a class diagramme or a state diagramme diagramme, you do so with a goal in communicating an idea. Some classes are in the middle because people care about them more. They are the principle class in the diagramme. They matter. The other classes are there because they interact with that/those class(es). Moreover, many class relationships exist but don't matter in understanding the motivation for having that class. (Old versions of Together would draw a relationship between my class and String or Integer. This is technically correct. But get it out of my face! The relationships between say Customer, SalesRep and Company matter. The 40 relationships Customer has with String do not.) If you have a screwed up code, then it takes the hand of a human to build the diagramme. The end diagramme will refactor the code. Rather, the process of drawing the diagramme will show the weaknesses in the code. I don't believe that there is any short cut to refactoring. Someone must understand the mess. 30 diagrammes, one for each class, will not help much, simply because examining 30 diagrammes is daunting and tedious. Besides, if the app is hand coded, the classes are likely to be reasonably coherent when viewed individually - that is not far from the programmer view. It is holistically that they will breakdown - circular dependencies, tight and fragile coupling. I want a diagramme to show me something that I can't see in the code. Now, if you want to do some scripting, you could look into reporting statistics about classes - number of relationships, relationships by package, dependencies by relationship, dependencies by interface (in method parameters)... and look for exceptions - high, low, average.. But probably a lot of this exists somewhere so perhaps archeology is more needed.
