In the moment it is only possible to create batch DWG files with the correct filename. It is very time consuming to print PDF files from Revit as each sheet has to be printed and named individually. Changing a title block information in a project which has 450 sheets and reprinting the updated PDF files is very time consuming.
Revit should incorporate an Export function to PDF where all or a set of sheets can be selected and the filename for each sheet is automatic as in the DWG export.
