We are having trouble in our office with drawings placed on layouts having their links broken in AC11. They are internal drawings (details), their names and locations within the file structure have not changed but when looked up in the drawing manager the have a red triangle and read "Unavailable". All the other information is similar to the links that are working properly.
This only happens with some of the placed drawings. There does not seem to be a corresponding detail marker or layout sheet that this problem is specific too.
We can go back and relink the drawings but the next time it is reopened the same links are removed once again.
Has anyone else run into this issue? Any suggestions who be greatly appreciated.
Thank you.
