Lars,
Thanks anyway. I had to make sure I hadn't missed something. We were
evaluating Visio as well. Although Visio does have this functionality, I
still prefer Dia because the saved images are XML. This allows round-trip
engineering which is one of the most important parts of a UML tool.
Cheers,
Richard.
