i was reading in the help files, somewhere, that you could define a diagram, with grandparent, parent, and child elements, and them associate a set of classes with the same structure, and then when you drag the grandparent onto the class/package diagram you would automaticly get the picture.
in other words, you develop a diagram for class BOB a(GP), b(P), c(C) and then when you say that a person class, is like/inheirated/ etc, a bob class, then you get the same diagram as you drag a Person on to the screen as you saw in the A/B/C picture. all help is appreciated.
