Jukka, The overlapping case has a technical solution (which is not implemented in mapserver) if you are willing to eventually offset your dash pattern at every line vertice. The adjacent case has no solution I can think of (draw two adjacent concentric circles on a whiteboard and try to dash them if you don't believe me :) -- thomas
