I'm working within ArcToolbox. I understand how to create toolboxes and the scripts that accompany them. Most toolbox scripts have a validation script. (Right click tool -> Properties -> Validation tab).
I have created a tool using ModelBuilder that runs very similar to the Strip Map Index Features tool(Cartography Tools -> Data Driven Pages - > Strip Map Index Features). I have just added a few more fields to the attribute table.
Is it possible to include / create a validation script for tools built using ModelBuilder?
