Umbrello is a UML modeling application and code generator from KDE. It can model software and other systems using a range of standard UML diagram types.
The application combines graphical modeling with code-generation facilities and uses XMI for model interchange. Its interface provides a tree view of the model alongside the diagram workspace and supporting documentation facilities.
This is free and open source software.
