Does this tool support code -> uml reverse engineering and roundtrip (code -> uml -> code) engineering?
From a brief look at it, it appears it does not. In which case there's better alternatives that are cheap. I'd prefer a Microsoft provided tool integrated into the IDE, but without those features I'll personally keep to the one provided by sparxx systems
(which can also integrate into the IDE, though I've always used it externally).
I'd say if you want your UML tool to be taken seriously it's going to need the described features. The dependency diagram generation looks interesting. But, again, there are fairly cheap alternatives that are much more powerful if you're interested in
code analysis (incl. dependency analysis).
And, ... is there any way of changing the default colors for lines on the generated dependency graph? Some of the choice of colors make some of the diagram lines practically invisible.
Overall, unless I'm missing something, I'd say this tool still has a long way to go, before it offers a reasonable alternative to external tools.
