I am working on an app that will export DWGs, PDFs, and DWFs bases on saved view sets and print settings. I see that in the DWFExportOptions the PaperFormat property desires a value from the ExportPaperFormat object. Within the ExportPaperFormat object there is no "Legal" (8.5x14) option. Is there a way to gain access to the "<Use Sheet Size>" option that is available when manually exporting a DWF. With this option selected in the Print Setup for the "Revit DWF Exporter" I can manually export a DWF on a Legal size sheet. Also, when I begin my code I get a warning that states "Adobe PDF cannot be used with DWF Export print settings. The <in-session> print settings will be used.". The "DWF Export" is a saved print setting created while manually exporting the DWFs.
