ArcPy Scalebar Implementation Issue

YahyaMasri — Fri, 07 Feb 2025 17:24:23 GMT

I am working on a standalone ArcPy script running FULLY out of the ArcGIS Pro application and I am running into an issue regarding the implementation of a scalebar. Currently, my script can add a scalebar however the scalebar says 0 KM and is a very small sliver shown below. I think the issue lies in the scalebar element not recognizing the map it's supposed to access. Previously this was not an issue when running the arcpy script in the ArcGIS Pro application since I used a line which include ("CURRENT") which helped the tools identify the map. If someone could help that would be great!

Try this,

scalebars = layout.listElements("MAPSURROUND_ELEMENT") sb = None for s in scalebars: if s.name == "Scale Bar": sb = s break if sb: print(f"Scalebar Found: {sb.name}") # Scalebar linked to the map frame if sb.mapFrame.name != mf.name: sb.mapFrame = mf # map frame print(f"Scalebar linked to map frame: {mf.name}")
