As I was testing suggestions from ESRI tech support, I noticed the following. I am able to merge the parcels in a shapefile. However, there are tiny gaps along one side of the parcels to be merged together. The merge process in the shapefile creates some small "donuts" in the new parcel. These small gaps must have been created when the parcel fabric was built, as I cannot find them in my original parcel data. Is there a parcel editor tool similar to the old "zipper" tool that can stitch this edge together? I think that may be the problem. I have attached the shapefile containing the parcels to be merged (PID 581721110) and two adjacent parcels. Please let me know if there is something I can do with the data (zip the edge?) prior to the merge to make it work out. Thank you.
