Hi, Dan.
Thanks for always being here to answer my questions. So I tried, and these relationship types don't seem to be allowed. Next, I tried the intersect with a 25ft search radius, and it didn't make much of a difference in the test case I was looking at. So I increased the amount to 500ft, even slightly more than I needed. So, I think there is an ideal choice in the search radius. The polygons are a grid of 3280 x 3280 ft. When I choose 200 ft that works for my test case at least, but I am left wondering if there is a mathematical rule here? Thanks, Derek
