With only the 3 cirlces, that would work, but when I have 35 individual polyline areas with arcs, suddenly this method feels like it will break down. It seems I could grab all objects, convert them to Regions 2 at a time, and compare their Union'ed area to their individual area, to determine if they overlapped at all. I'm clearly going to have to be converting the various boundaries to Regions, and performing some Unions. So, as in a Venn diagram, the areas where only one circle is present can then get shaded one color, areas where two circles are overlapping can get a different color, and the area where all three circles overlap can get a third color. But I need this to work with closed polylines, that may also have arc segments in them.Īnyway, so I have these intersecting areas, and I need to create bounding polylines for each area, and assess the number of overlaps. So for the purposes of this exercise, let's assume it's the classic Venn diagram of three intersecting circles.
