Hi, I am trying to create a tool that can run through all the field names in a parameter and assign field aliases for certain fields. I basically have many feature classes with pretty much the same fields that I would like to run this tool on to assign more readable aliases for others who see it. All I have really been able to come up with is a tool that is composed of a centipede of alter field tools, the only problem is, there are about 100 fields in the feature classes and I would want a more elegant tool. Is there any direction I should take? I am grasping model builder well but am very new to python.
