So, maybe you’re doing an environmental analysis (check out my Create Random Points tool) and need to split a study area into equal plots? Or you work for a government agency and need to create a quarter or quarter section grid? Or you work for a utility company and need to split up an area in order to create features in correct locations? The possibilities are endless…

This tool allows a user to create a custom polygon grid of any size from an existing polygon feature class.

It loops through each polygon feature and splits it into whatever division was chosen.

This tool was created using Python, or more specifically ESRI’s ArcPy module.

Be sure to view the Tool Help within the tool dialog box for detailed instructions. Also, check the Geoprocessing Results for any error messages.

Okay, enough of that. I think you get the point. I hope someone can find this tool useful.
