I have a feature class of around 3500 multi-part polygons. The multi-part polygons include many islands. I'm running topology rule "must not have gaps" on to fix gaps between polygons/sliver polygons. Running this rule shows almost 18000 errors. The vast majority of these 18000 errors are islands, which are not errors. Rather than going thru each record and marking them as exceptions, is there an easy way to exclude the islands? Or another way of going about trying to accomplish my task.
