A great contribution definately credits worthy thanks!
By the way, does anyone have some tips concerning a 'level radar' ? My plan is to make a radar on which also lines are visible from buildings (most probably they are models too, but I only want an outline), I remember I must have got some code which will draw a the boundary box lines, so it must be possible somehow.. I want to keep it simple though, anyone some suggestions for this?

Cheers
