You can recover from minor changes such as a moved or renamed drawing.
When a data shortcut reference is broken, the 
icon is displayed next to the invalid data shortcut in Toolspace, on the Prospector tab for the host or consumer drawing.
Broken references typically occur if a source drawing has been renamed or moved to a different folder. If you can identify the new name or location, it is quite easy to repair the references. If the source drawing contains multiple data shortcuts, once you identify the drawing you are prompted to repair all of the references.
- In Toolspace, on the Prospector tab, right-click the object name of the broken reference, and then click Repair Broken References.
- In the Choose the File dialog box, navigate to the source drawing for the referenced object, and then click Open.
If the source drawing contains other broken references, the Additional Broken References dialog is displayed. You can click the Repair All Broken References button, or click Cancel to repair only the broken reference you selected.
