I have (3) SW drawings containing three top level assembly's. They are all very similar. After creating one drawing with the first assembly, I used the "Pack and Go: function to create the other two (then modified the features that were dis-similar). I added the (3) drawings and (of course) assembly's. When I view any of the drawing files - each one shows references back to the other drawing files - even though there really shouldn't be any relations to those drawings. These references to the drawing files are in blue - while all other files are black. Any idea why this is happening?
