If is about a drawing template u can draw what u want in a new drawing file. save it in a safe location (read only folder is proffered) . Then unu File -> New From and indicate the file u have save it as template.
I suggest to also go in Tool-> Options ->Mechanical Design -> Drafting -> Administration and check Prevent File>New.
In this way u can't make new drawings, only New From Drawings (users are forced to use the templates).
