I know, I have a difficult time fathoming that myself.
My company needs some sort of actual CAD standard.
Instead of 1 CAD dept., there are separate dept's and
no one is following their own standard. I work in the
Electrical dept. and when I was hired back in 2005, the only standard that this dept. were using and I was told by the "Cad Coordinator", to use Structural/Civil standards from his dept. ???? Exactly. Whacky World over here. So, I took the liberty to creating an Electrical Standard for drafting and currently creating/updating details we use here.
