Job Number
The inclusion of the Job Number not only identifies
the project, but it also helps to maintain file individu-
ality so no two files are named the same on the serv-
er. Use the entire Job Number.
Drawing Numbers
Drawing Numbers start at 01, If an additional file
is needed the next number in numeric order
would be used.
