Note: if the user cancels the operation (for example, through ESC), the method will throw an OperationCanceledException instance.

Revit users will be permitted to manipulate the Revit view (zooming, panning, and rotating the view), but will not be permitted to click other items in the Revit user interface. Users are not permitted to switch the active view, close the active document or Revit application in the pick session, otherwise an exception will be thrown.
