I'm totally new to ArcGIS 10, I'm trying to edit some polygons that partecipate in a topology, in addition all these geometries are sotred in mdb database as few feature classes and they appear as different layers in the map beacuse I set queries. I searched on the forum and I see that the problem is connected to the reasons I explained before but I really can't understand what do I have to do in order to edit these geometries.</SPAN></BODY></HTML> Fri, 04 May 2012 09:08:10 GMT AlessandroCristofori 2012-05-04T09:08:10Z Can't edit features "The opeation cannot be performed on a non-simple geometry"? https://community.esri.com/t5/data-management-questions/can-t-edit-features-quot-the-opeation-cannot-be/m-p/377839#M21477 <HTML><HEAD></HEAD><BODY><SPAN>What does this mean?
