Round-trip engineering #Is it possible to keep diagrams and code in sync?

Constraints *Availability # Price #Student/academic edition *Performance #Is drawing and manipulating diagrams realtime? *Open #Can the tool be combined with other tools? *Open source #Is it possible to improve and extend the tool?
