I have a UTM grid within my map frame, and I would like to use arcpy to change its projection.
As far as I can see that can only be done with a CIM definition.
I'm getting an error. Any ideas? Or am I on the wrong path?
....
cim_mapframe = first_mapframe.getDefinition('V3')
cim_mapframe.grids[0].projectedCoordinateSystem = arcpy.SpatialReference(7854)
first_mapframe.setDefinition(cim_mapframe)
I get an error when on the setDefinition line.
AttributeError: SpatialReference: Get attribute X does not exist
