Currently you could calculate the <A href="https://developers.arcgis.com/arcade/function-reference/geometry_functions/#centroid" target="_blank" rel="noopener">centroid</A>&nbsp;as an attribute rule, but only in the native projection.</P><P>There is an idea currently open that would help with that functionality:&nbsp;<A href="https://community.esri.com/t5/arcgis-pro-ideas/arcade-projectas-geometry-function/idc-p/1330085" target="_blank" rel="noopener">Project as Geometry function</A></P><P>Give it an upvote and hopefully we'll get in a few releases.&nbsp;</P><P>&nbsp;</P> Wed, 04 Oct 2023 14:34:55 GMT https://community.esri.com/t5/arcgis-pro-questions/calculate-centroid-on-polygon-feature-based-on/m-p/1334933#M73682 AlfredBaldenweck 2023-10-04T14:34:55Z
