      Sorry Mathias,

      maybe it is because of my bad example...

      Is it possible to outline any group of shapes ? The 2 circles was
      just an example of a group. I appreciate that I could do this using
      intersections for this example, but I am after a method for doing
      any group of shapes. I might consider a filter, and shall have a
      hunt!

      Cheers,

      Simon.
