Hello,
I have a set of polygons (made from buffered points) that represent bird foraging areas.  In some places these polygons intersect, and where they do I would like to split the intersecting region into two equal areas that can be allocated to one foraging area or another (see attached image).  I can't find an easy way to divide the intersecting region so that the areas of the two resulting polygons are equal.
Any help would be much appreciated.
Cheers,
CG

I'm also having this problem right now.  I have an irregularly shaped polygon I need to divide into 20 equal areas, so the split tool will not work.

I found this:

It looks like it might only be available in v. 10, but I'm not sure yet.

You could generate Theissian (Voroni) Polygons from the points, and use them to split a merged buffer polygon using Identity, or clip the individual buffer circles.
