Had a couple helpful illustrator scripts that I wanted to share...
1) Monoline Text

With this simple script first select an item in your file then run the script. Measurements are in mm and are created on a new layer and grouped for easy repositioning. Useful when generating digital proofs for a third party. You can edit the code to have it output inches.
