The document tested is a drawing.  

Apply the operation according to the number of views present on one or more sheets of the drawing.

The operation only applies if the drawing contains one or more views on a particular sheet or on several sheets of the drawing being processed.


Example If the number of views on all sheets in the drawing is equal to "3" then the operation is applied.

 

But it is possible to specify the name of the sheet for which to check the number of views, so as not to process all the sheets in the drawing.
