I am currently developing a standalone python script to create a 3D scene. The points that I am plotting have a height component relative to the ground. Currently, my default for ground elevation is set to absolute and I need to manually change it to relative to the ground. Any suggestions on how to this using arcpy? I've been searching but not much luck. Thanks!&nbsp;</P> Fri, 10 Mar 2023 19:26:00 GMT https://community.esri.com/t5/arcgis-pro-questions/setting-elevation-using-arcpy/m-p/1266618#M66517 saldanax 2023-03-10T19:26:00Z https://community.esri.com/t5/arcgis-pro-questions/setting-elevation-using-arcpy/m-p/1266737#M66523 <P>Hi,</P><P>There is no out of the box property available but you can backdoor it by updating the CIM for the layer.
