Currently it is not possible to allow for drawings to have no format while using ModelCheck FORMAT_NAME option. Please add an option to allow no format as we create DXF drawings without drawing formats and need an ModelCheck option to allow a drawing to not have a format. This would be option the Creo Admins could decide to use or ignore. Another way to "solve" this today would be turning off the format display but this would require a change of a lot of legacy drawings. It would be much simpler to have to option of allowing no formats or not.
