https://community.esri.com/t5/arcgis-pro-questions/undo-a-split-that-deleted-data/m-p/1262277#M66008 <P>How can I undo a Split? I ran a Split on my polygon feature layer about a month ago and it deleted all the polygons that were on the borders of my "Split Features" layer (which was a layer of political boundaries). I want to undo this, because it reduced the amount of data I have. How can I accomplish this?</P> Tue, 28 Feb 2023 04:13:16 GMT htracy 2023-02-28T04:13:16Z https://community.esri.com/t5/arcgis-pro-questions/undo-a-split-that-deleted-data/m-p/1262277#M66008 <P>How can I undo a Split?

You can only recreate the deleted features by copying from a backup of your feature class or from the original data.</P><P>&nbsp;</P><P>If your feature class is <A href="https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/overview/overview-of-versioning-in-arcgis-pro.htm" target="_blank" rel="noopener">versioned</A>, you can <A href="https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/overview/work-with-the-archive-class.htm#:~:text=Add%20the%20archive%20class%20to%20a%20map,-The%20archive%20class&amp;text=To%20add%20an%20archive%20class,button%20in%20the%20Archiving%20group." target="_blank" rel="noopener">add the archive to the map</A> and get the historic features from there.</P><P>If you made manual backups of your data, you could go back to a backup before the split and copy the missing features to your current feature class.</P><P>If you're working on a network drive, you can talk to your IT department, they might be doing automatic backups.</P><P>If none nof these apply, you're probably out of luck and have to redo your whole workflow for the deleted polygons.</P> Tue, 28 Feb 2023 08:19:17 GMT https://community.esri.com/t5/arcgis-pro-questions/undo-a-split-that-deleted-data/m-p/1262352#M66011 JohannesLindner 2023-02-28T08:19:17Z
