I can only split the polygon without the box checked and polygon selected.</P> Thu, 20 Nov 2025 19:53:47 GMT https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-won-t-allow-splitting-without-a/m-p/1667652#M100301 CarolynScholl4 2025-11-20T19:53:47Z https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-won-t-allow-splitting-without-a/m-p/1667661#M100303 <P>Hi&nbsp;<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/919106">@CarolynScholl4</a>&nbsp; Can you provide a screenshot of the polygon and the Split line you are sketching?&nbsp; Is the polygon data projected on the fly?</P> Thu, 20 Nov 2025 20:19:23 GMT https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-won-t-allow-splitting-without-a/m-p/1667661#M100303 JenniferCadkin 2025-11-20T20:19:23Z https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-won-t-allow-splitting-without-a/m-p/1667705#M100306 <P>version of Pro?&nbsp; are the map and layer in the same coordinate system?</P><P><A href="https://support.esri.com/en-us/bug/when-using-the-split-tool-from-the-modify-features-pane-bug-000172550" target="_blank">BUG-000172550 for ArcGIS Pro</A></P> Thu, 20 Nov 2025 21:42:17 GMT https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-won-t-allow-splitting-without-a/m-p/1667705#M100306 DanPatterson 2025-11-20T21:42:17Z https://community.esri.com/t5/arcgis-pro-questions/arcgis-pro-won-t-allow-splitting-without-a/m-p/1667720#M100308 <P>Yep, that was the problem.
