I have been using the right click, SolidWorks, Rename & SolidWorks Explorer rename for some time now and never had any issues with keeping relations. Since switching to SW 2008 I have noticed that the references do not keep if I use these methods any more. This is causing serious problems. When it comes up with my Where Used list it is only listing references within the main folder where the model is located. In the SolidWorks Explorer options I have switched to "Show all levels of references" and added the main CAD directory at our company into the File Locations box. It will work then but it takes an extremely long time to search through all folders in the CAD directory. Does anyone have any suggestions for me or help. This is causing major headaches.
