Since R17, when we do a "Print PDF" with multiple files, Revit just fails the job. Before doing the multiple files, we have to do a "Current Window" then a "Preview". Once the "Preview" is done, we can do a "Selected views/sheets" and "Combine multiple selected views/sheets into a single file". Why before R17 the print PDF multiple files was working and that it doesn't works for all the newer versions?!? 😞
