https://community.esri.com/t5/arcgis-pro-questions/how-do-i-merge-polygons-based-on-common-attribute/m-p/1219988#M60843 <P>I have parcels that were split in the process of joining them to a subdivision polygon layer. I used the dissolve tool since there was repeats. I used the Property ID to merge them together since this is unique value. The count number reduced dramatically. It creates a new table, but my problem is that it only contains OBJID, shape, Property Id, shape length and area but not all other attributes. I tried to do a join based on property id but the OBJID now has repeats, and the count goes up again from original attribute table.</P> Thu, 13 Oct 2022 21:45:47 GMT Krocha 2022-10-13T21:45:47Z https://community.esri.com/t5/arcgis-pro-questions/how-do-i-merge-polygons-based-on-common-attribute/m-p/1219988#M60843 <P>I have parcels that were split in the process of joining them to a subdivision polygon layer.
