I cooked up the static structure of my assembly through the Visio UML option in the Project Menu in VS.Net 2003. It got added to the solution. However, when I open up this file in Visio, nothing shows up. the Model Explorer displays the complete list of classes but the phydical layout is not on the screen. Am i missin anything in here?? Would like to hear some cool advise from visio gurus outta there.
