    Hi chm,

    Thanks for the reply

    I have actually used class diagrams (I wrote sequence in first post by mistake) and I've used unmask > child generalisations on root class but I've got just a few direct subclasses of root class (3 of more then 20)...

    Hi aurelije,

    first of all, a Sequence diagram isn't really appropriare in your case, you better use a Class diagram.

    You were right to use the 'unmask' menu, but the 'parent generalization' command unmasks the super classes...
