I have made simple uml diagrams with dia.
If you go to the end of this web page

  http://cs.nyu.edu/~gottlieb/courses/ds/class-notes.html

You will see some of them.

On item to note when using snap to grid.
If you start at a given zoom (say 200%) and draw a shape with all
vertices on the grid and then exactly double the zoom
(in this case 400%), the vertices might no longer be on the grid.  I
often have to use high zoom 800 or more to get the vertices to stay on
the grid at 200.
