Use this window to compare engineering structures to see how they differ. The different revisions are displayed simultaneously in a split window where you can choose to see either the entire structure or just the part that has changed. There are four options that enable you to view different aspects of the comparison. They are All, Equal, Difference, and Tree. You can display the Structure Comparing Tree dialog box by clicking the Tree option. You cannot add, update, or delete information in this window.
Note: You can compare only one level of the structures at a time.
