Which layer are you using?&nbsp;&nbsp;</P> Fri, 20 Sep 2024 06:00:05 GMT ShabbirRaza 2024-09-20T06:00:05Z https://community.esri.com/t5/arcgis-pro-questions/union-tool-errors/m-p/1540583#M88522 <P>Hello everyone,&nbsp;<BR /><BR />I've trying to use Union Tool to have a final feature layer so that I can assign runoff curve numbers to each soil type-land use combination. However. Union tool is giving me an error of invalid topology (ERROR:160196).<BR />How can I solve this problem?&nbsp;<BR /><BR />Thanks!</P> Thu, 19 Sep 2024 19:08:29 GMT https://community.esri.com/t5/arcgis-pro-questions/union-tool-errors/m-p/1540583#M88522 SunaMorkoc 2024-09-19T19:08:29Z https://community.esri.com/t5/arcgis-pro-questions/union-tool-errors/m-p/1540775#M88523 <P>First, there are different tools for union (raster layer or vector layer).
