UML Sculptor is a lightweight UML modeling tool for class diagrams.

It is not a complete UML solution, it doesn't do round-trip engineering and it consists of only a single executable file. But because of that, it's exceptionally quick, easy to use and provides an excellent workflow.

For example, to add a method to a class, instead of selecting a class, then opening a tool window, picking public/private from a combo box, entering a name, clicking on 'add parameter', yadda yadda -- in UML sculptor, you just click right below the methods compartiment of your class and enter + myMethod(arg : int). No tool windows, no dialogs. It feels just like drawing the diagram on paper!

That makes it ideal for quick sketching and planning, where I very much prefer it to bulky, full-featured UML designers.

This is a modified release of the original UML Sculptor, statically linked against the Visual C++ runtime so it runs without installation. I also added the ability to directly export UML diagrams to SVG (XML-based vector graphics format supported by all modern browsers except for Internet Explorer.)
