I have a series of 16 maps. Within those maps I need to change the symbology for a feature class. Without opening each map and make the changes individually , does anyone know how to automate this? Maybe with ArcPy or Model Builder?
Hopefully, all your maps are in the same folder(or at least have a similar root folder), and you can loop through each map document, select the dataframe that layer is in, find that layer then change the symbology. If the layer is named the same(or have a name that is similar) in all the map documents, this should be a fairly easy process.
