Use this window to compare the design and manufacturing structures, especially to note their differences. The different revisions, named the Transfer Structure and Manufacturing Structure, are displayed simultaneously in a split window where you can choose to see either the entire structure or just the part that has changed. You cannot add, update, or delete information in this window, and you can compare only one level of the structures at a time. There are four options enabling you to view different aspects of the comparison: All to compare parts of both structures, Equal to compare only those parts of both structures that are the same, Difference to compare only those parts of both structures that are different, and Tree to compare structures in their entirety. You can close and open levels, but you cannot drag and drop.
