I'm using SolidWorks 2006 SP0.0 and I'm having trouble replacing references in a drawing. I close all the files that are open click open find the drawing I want to replace files click references double click the file I want to change browse to the new file and click open then I click the checkmark click ok open the file and nothing changes I don't get any errors either which is kind of strange. Does anybody have any tips or suggestions? I'm so confused as to why this would do this I've been spending all day trying to figure this thing out, I'm stumped.
