Cause
If this problem occurs only with a single drawing or a small group of similar diagrams, your drawing or diagrams probably are damaged.
Resolution
The information and shapes in a damaged or corrupted drawing can seldom be recovered.
The best way to protect yourself against the data loss that results from a damaged drawing is to keep backup copies of your diagrams. As an alternate to keeping a separate backup copy, you can work with a copy of the Visio drawing instead of the original. To do this, follow these steps:
-
On the File menu, click Open.
-
In the Open dialog box, select a drawing, click the arrow on the Open button, and then click Copy.
Note In Visio 2007, click the arrow on the Open button, and then click Open as Copy.
