I'm trying to find the shortest edge-to-edge distance between polygons in a layer. An example is a table of the distances from county to county in a state. I'm attempting to use the generate near table tool. I set the proximity to 0 and made sure to de-select only the nearest neighbor. It runs for a few hrs, but when its finished, the ouput only returns the distance of the 1 nearest neighbor, which is 0 because they are touching each other. Any help would be much appreciated!
