I don't know when this started, but the last time I did major editing was either 3.1.1 or 3.1.2. The only difference now is that I know there are still floating edges without adjacent polygons elsewhere.</P><P>I have attached a photo of the movement demonstrated between two common edges that were not involved in the most recent edit.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="polygonError.png" style="width: 543px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/100531iF36B57E9F42972BC/image-size/large?v=v2&amp;px=999" role="button" title="polygonError.png" alt="polygonError.png" /></span></P> Tue, 09 Apr 2024 21:52:02 GMT https://community.esri.com/t5/arcgis-pro-questions/polygons-shifting-when-deleting-vertices-with-map/m-p/1407751#M81643 BenZalneraitis 2024-04-09T21:52:02Z Re: Polygons shifting when deleting vertices with map topology enabled https://community.esri.com/t5/arcgis-pro-questions/polygons-shifting-when-deleting-vertices-with-map/m-p/1417079#M82554 <P>It seems to have happened because I was working in NAD27 for the sake of my historical data, and the file I'm editing is being projected on the fly from NAD83.
