External Reference Status
In the External References palette, in the List View, there is a status column. As you might expect, this informs you of the status of the reference file. Have you ever seen a status that you did not know the meaning of? There are SIX documented states for a reference file, plus at least one more.
- Loaded - The reference file is currently loaded and attached, and there are no issues.
- Unloaded - The reference file is unloaded, but still attached to the drawing. This does not indicate a problem either.
- Not Found - AutoCAD could not find the reference file in its saved path or by other methods.
- Unresolved - The reference file cannot be read (for example: the reference file was saved by a newer version of AutoCAD)
- Orphaned - This indicates a nested reference with a status of Unresolved in its parent drawing.
- Unreferenced - This means the reference geometry was deleted from the drawing, but the reference itself was not removed.
- Needs Reloading - This means that the reference file has been updated and needs to be reloaded. I have seen this status immediately upon opening a drawing when I know the reference file has not been updated - so I'm not quite sure of the criteria used to determine whether or not to display this status.
Below are some examples of the various states.
