I really appreciate the detailed information provided in the new Collision Data format Damage Data report for EDSMAC4 in my Version 8.20 software, but how do I change back to the Traditional format that I am used to working with for the past years?

To toggle back and forth between the new CollisionData and standard Traditional formats, you need to first be in the Event Editor and then use the Calculation Options dialog to change the setting in the bottom portion of the dialog. To access the Calculation Options dialog for your event, select Options>Calculation Options on the main menu. When you reset and run your event, the Damage Data report information will be generated in the format you selected.
