A good starting point to investigate this is to open the drawing, then go to File > Find Referances.
Also when you are first opening a file, there is a button called "References" that comes up when you have a file selected but before you actually open it. Confirming that the information in these places is correct will help solve this problem.
Off hand, I'm wondering if the drawing is referencing something on the computer it was orginally on, but then when you open it on your computer that information isn't there. Or you need some kind of special permission to get to those files?
Or maybe your opening files out of a compressed (.zip) folder. Sometimes SW has problems opening referenced files from such things.
Once file is open and I have pointed to the correct part file, File>Find References will show the correct file path, and the correct file.
If I cancel out of the open file dialogue, however, File>Find Reference will show the correct file path and the correct file, but will append "(not open)" to the file name shown.
If I hit the "References" button when selecting the drawing document inside the 'Open File' dialogue, I get an error message: "Cannot edit file reference. Either file is not a valid Solidworks document, or has not been saved in Solidworks 97 or later."
The files are saved as SW 2012 and open fine on other machines
I don't have these issues on the other computers in our system.
Jeremy, verify that the checkbox labelled 'search file locations for external references,' is unchecked. It's in in Options:System Options: External References. When checked, Solidworks goes through a search algorythm that doesn't include the location stored in the assembly. When unchecked, Solidworks will look for assembly references in the locations they were loaded from when the assembly was last saved.
I tried unchecking that option, and it didn't make a difference.
Do you know if that option will apply to drawings, or only to assemblies?
Do you use a PDM system? I have seen times when references got messed up and SW was looking for files on one of the other user's computers. This seemed to be related to issues with WPDM, but I'm not completely sure about that. We definitely had problems with lost references when we were using Activault, but that was many years ago, so it may no longer be an issue.
We are not using any PDM system.
What gets me is it only happens on my machine in our entire system, which makes me think it must be a setting or corrupt filepath link?
