I am trying to generate a large number of plans using the Data Driven Pages in ArcGIS Desktop.
I have created an index layer comprising a series of rectangle features that correspond to set scales on my layout page (eg 1:100, 1:500, etc). Due to the odd arrangement of the features I laid out the plans with rectangles that are often rotated. There wasn't a particular feature that I could use alternatively to create a nice layout using strip or grid tools.
I can see in the data driven page there is an option to include rotation. However I cannot figure out how to measure the rotation of the rectangle features.
Is there a way to do this automatically in the attribute table, similar to the way you can calculate geometry?
