SYMPTOMS
In Microsoft Office Visio, when you open a Visio (.vsd) drawing that contains a CAD display object, and then you try to ungroup the CAD display object, you receive the following error message:

An error (1411) occurred during the action Ungroup

There was an error reading or writing OLE data.

Note To ungroup the CAD display object, on the Shape menu, point to Grouping, and then click Ungroup.



CAUSE
This problem occurs because Visio does not support the use of the Ungroup function to modify a CAD display object in a Visio drawing, even though the Ungroup command is available in Visio when you are working with a CAD display object.



WORKAROUND
To work around this problem, you must convert the CAD object in the Visio drawing to Visio shapes. After you convert the CAD object, you can modify or delete the shapes in the Visio drawing. To convert the CAD object to Visio shapes, follow these steps:
 * 1) Start Visio.
 * 2) On the File menu, click Open.
 * 3) Locate the file that contains the CAD object, and then click Open.
 * 4) Right-click inside the drawing that you just opened, point to CAD Drawing Object, click Convert, and then click OK.

After the conversion is complete, you can modify the Visio shapes in the drawing.



MORE INFORMATION
Visio supports the automatic conversion of certain OLE objects into Visio shapes. The Ungroup command converts file formats like .wmf and .emf files. However, CAD objects must be converted by using the process in the &quot;Workaround&quot; section in this article.
