Is the functionality behind the <SPAN class="">Scale Range View</SPAN> in the Symbology pane exposed in ArcPy or API? I searched the online documentation for both but could not find references to changing symbol class scale range. This seems to me like a significant omission, especially given that using the Scale Range View can involve lots of finicky mouse clicking and spinny icon waits after each change.</P></BODY></HTML> Tue, 21 Nov 2017 16:57:26 GMT https://community.esri.com/t5/arcgis-pro-questions/is-it-possible-to-work-with-arcgis-pro-scale-based/m-p/380709#M16732 RobertJones11 2017-11-21T16:57:26Z Re: Is it possible to work with ArcGIS Pro scale-based symbol classes in code? https://community.esri.com/t5/arcgis-pro-questions/is-it-possible-to-work-with-arcgis-pro-scale-based/m-p/380710#M16733 <HTML><HEAD></HEAD><BODY><P>I made some progress.
