BIM Software Tips: How to Fix the Clipboard Copy Failure in AutoCAD
When you try to copy an object to the clipboard (CTRL+C) from an AutoCAD drawing, you might encounter the following error message:
Cannot copy to clipboard
This happens because:
The selection set contains proxy objects that cannot be processed during the copy operation.
Solution:
Copying proxy objects requires an object enabler. When you open a file containing such objects, AutoCAD usually displays a proxy warning informing you about missing applications needed to manage these objects. If you do not see this dialog box, set the PROXYNOTICE system variable to 1 to enable the notification.
If obtaining an object enabler is not possible, try these alternative steps to resolve the issue:
- Clean and repair the graphics in your drawing.
- Use the
WBLOCKcommand to save the graphic elements to a new file, which may help bypass the proxy object restrictions.
