Error message when attempting to move a viewport

[eitanCZ3K3]

In Revit 2026, there seems to be a bug whereby using the move command to move a viewport produces an error message that "selection cannot be copied".

Hi, @eitanCZ3K3 ,

This sounds like a bug. Could you file a problem report in your Autodesk Account (manage.autodesk.com)?

Also we will move this thread to the forums for support.

Thank you!

Hi @eitanCZ3K3

Have you checked that the disjoin function is not active? If active, then you will get this error every time.
