Revit does not allow the same DWG view to be placed in more than one sheet. For this reason, when we want to move a set of views from one sheet to another, it does not let copy or cut and paste. It gives a “multiple instances of the same view in sheets not supported!”
One way to move the views, is to open the sheets category in the project browser
and just drag and drop the views to another sheet in the project browser or in the DWG area.
