Hi Roger,

One option is to trace the polygon by setting the
'points' property to the individual points of the
invisible polygon ; something like :
--
put the points of graphic "invisiblePolygon" into \
    tInvisiblePoints
repeat for each line tPoint in tInvisiblePoints
  put return & tPoint after tVisiblePoints
  set the points of graphic "visiblePolygon" to \
      tVisiblePoints
  wait 1 second
end repeat
--

Hope this helped,

Jan Schenkel.
