I've got an assembly file with a 20 or so part references. Recently, when I open the file I get the ( 2 blanked entities found in part) message. I then go to the unblank entities icon and click on it and it responds with (There are no blank entities). I just go on and work on the file with no apparent problems, everything that is suppose to be there, is there. What is happening and how can I clear this out. Could the "blanked entities" be within a reference? I have opened most of the reference files and have not found any blanked parts within them. Any thoughts?
