adding reverse engineered classes to Model Explorer

[Dave]

Hi,

I have used Visio 2007 to reverse engineer some Visual Studio 6.0 C++
code. I did this from within visual studio.

I have used the resulting elements in the Model Explorer pane to
produce some class diagrams and sequence diagrams that really impress
management! However, I have realized that I need some classes for my
sequence diagrams from another C++ project. Can I somehow add some
classes to my model explorer? How do I initiate reverse engineer from
within Visio to do this? Alternatively, I could reverse engineer the
newly neeeded C++ project if I could find a way to import the
generated model into my existing model.

Any ideas?

Thanks,

Dave
