If you are using Revit to create PDF files for several views or sheets, this default setting means that you must provide a file name for each PDF file as it is created.

To avoid the need to provide individual file names for PDFs, change your system’s default PDF settings. The following procedure describes how to change this setting for Adobe® PDF. The steps may vary for other PDF drivers.
