Thanks for the feedback. I will make the link more intuitive. The William Bartle polygon looks OK when I view it. However, when sharing these files with other people, we have come across some problems in getting the polygons to display properly. If the 'altitude' property of the polygon is set to zero, it appears to be 'sunk' below the surface. Giving it a few metres elevation (depending on local topography) brings it into view, but sometimes it is only partially visible. Regards: Roger Donne
