Problem: I want to have the same relationship (same name) on both diagrams. I deleted the relationship on my second diagram and want to pull in the relationship from my first diagram, but I can't figure out how to do that. I thought I could just drag the relationship into the second diagram but that doesn't work.
Solution:
The way to add the relationship to the other diagram is to locate the diagram in the model explorer tree. Right click it and go into properties. Then on the relationships tab move the relationship into that diagram.
