There are many different ways how this could be realized with newer versions. Here is a palette that copies the ViewPoint of the currently selected Graphics3D to the clipboard:
CreatePalette[Button["Copy Viewpoint", Replace[ Cases[NotebookRead[SelectedNotebook[]], _[ ViewPoint, _], \[Infinity]], {v : (ViewPoint > _)} :> CopyToClipboard[v] ] ]]
If nothing is selected or the selection is not a Graphics3D (or contains exactly one of those) it won't change the clipboard content...
