I am wondering how others handle designating the dimension units on a drawing title block. I checked with PTC and they tell me there is no system parameter for units. Now I have a user defined parameter in my start part with a default value. The problem is if someone changes the units they must update the parameter manually. I want this format to work in Intralink for many users. I was hoping to make it invisible and fool proof. I am using 2001 with Intralink 3.3.
