Hello All,
I am trying to customise some UML operations like adding / deleting relations between classes. I do the operations using some VBA macros. But I am stuck up

updating the class diagrams after I am done with my changes in relations.... My model is kind of huge.... So that makes it difficult to remember and select all the class names to draw a new class diagram by Rhapsody Populate Diagram feature in Add New Structure Diagram.
I want to create a diagram using the same macro, so I that I dont need to remember all of it.
I found that we can do this IRPDiagram by addnewnodeforelement.
But this way I am not able to arrange the all nodes and relation edges in a hierarchial or orthogonal layout.. Which was possible when I do by the Rhapsody Populate Diagram feature.....
Is there a way to arrange the layout for the diagram by a VBA API?
Please help !!!! i would reallly appreciate any suggestions
