A system Parameter containing the working directory path would allow a drawing to be documented with the directory file location in which that drawing was developed. A requirement of some quality control procedures is to know and record the file directory of the source of the document. A Creo system parameter that can be accessed within a drawing would allow this to be parametric instead of having to enter the path manually. This would be a 'Creo' system parameter - available within drawings without the use of any product data management.
Original idea here!
