Hi, We use geoprocessing service in our application and one of the tool we are using is Aggregate Polygon tool in Cartography. This tool is being used to union two or more geometries which are at a particular distance from each other and these geometries can contain exclusions(inner ring).   But the issue we are facing is if the exclusion polygon(inner ring) contains 3 vertices, then Aggregate Polygon is removing the exclusion polygon. We tried with so many parameters and even tried with giving some values in Minimum_Hole_Size but no success.
