Ok, This is a first for me and this is going to cost me many hours to fix but I have a drawing file with 15 sheets and a seperate detail attached to each sheet. I had a change come through on one  component so I went the sheet containing that model, selected a view and used replace model and selected the updated model (imported from ProE) Well that worked fine EXCEPT EVERY print updated to that model. Did I not use the function correctly?
