I need to expediently make an identical change to the symbol size and color of multiple feature classes. This can be done for layer transparency through a script such as:
mxd = arcpy.mapping.MapDocument("CURRENT") for lyr in arcpy.mapping.ListLayers(mxd): if lyr.name == 'FC1' or 'FC2': if lyr.supports('TRANSPARENCY'): transparency = str(lyr.transparency) lyr.transparency = 45
But as far as I know, the color, size, and symbol type characteristics are not as easy to access and change. Any ideas on how this could be done?
