the option is to be put in .dtl and is "default_font"
attention to very particular fonts, which must be present in the windows library, I recommend staying on the classic fonts.
I finally found thanks,
remains a problem when molding a pdf does not keep the paper mill lines thickness if the file
is in the working directory, if instead I leave the working directory of default (creo_start) function well, in the configurations it is checked keeps
sketch settings
The thing I can't explain is that
if first launch a print with the default folder active as working directories, and then
active as working directories the workbook, everything works perfectly also the subsequent prints of the files present are perfect,
if instead I choose the workbook before and then I launch the prints the paper mill thicknesses are not respected.
