Reverse engineer multiple classs interactions

[FLDaveM]

Hi. I've been trying to find a way to get a diagram for the following
scenario:
I have a vb.net solution (about 15 classes, many routines, inheritance, etc)
that call one another. For example, Class A Funtion 1 calls Class E
Subroutine 15. I'd like this diagrammed in Visio (I have 2003). The VS.NET
reverse engineering seems to generate the information on each class, but I
can't get a flowchart or routine call-tree or whatever the term is I'm
looking for.

Any help would be appreciated!
Thanks,
Dave
