Data frame rotation configuration
10.2.1 is the final release in which MPS-Atlas is available for installation. It is recommended that map series created with MPS-Atlas be moved to data driven pages. For more information, see Migrating an MPS-Atlas map book to Data Driven Pages.
The Rotation dialog box allows you to choose from several options when calculating the rotation: No Rotation, Rotate to True North, Fixed Rotation, and Select From Field.
The first option allows you to leave the rotation value of the data frame as it stands. You can also designate a fixed rotation using a value along with a unit of measurement, rotate the data frame to true north, or use a field to determine the rotation value.
The option you choose determines the rotation that will be used for all the map sheets in your map series.
