Yeah I already noticed that ... distance + external angles defines the formation around the unit. But the solution I found is exactly what I needed. I knew it was right under my nose the problem was that it's called Info - Button - Requirements so I was thinking that this was a button icon or something. It was after I examined it closely I noticed that it's not just a button after all.
Thanks for the help guys.. I can't see any reputation system or something I can reward you with.
