I had an activity diagram that I wanted to duplicate.
There is no Save As or Copy/Paste option for diagrams. Unable to perform the
task, would have to re-create the diagram from scratch.
Clicked on Edit->Copy when the diagram was selected in the Projects View. Then
clicked Edit->Paste. I would expect it to create a copy of the diagram with a
name like "Copy of <original diagram name>", but nothing happens. No action.
Also please look at issue 83789:
Copying diagram items by hand and pasting them into a new diagram does not work
So basically there is no working option to duplicate/save as/copy a diagram in
any way it seems
see issue 79771
