"CL" Symbol Manditory? 1

[MadMango]

We are having some drawings kicked-back by QA due to not having the CL symbol to define a centerline in a cylindrical part drawing.

I looked in Y14.5M-1994, thinking that one of the Fundamental Rules stated you didn't need it, but couldn't find it. Can anyone help?

Some time ago I questioned whether the "CL" symbol actually existed in any written standard. I thought it was just "engineering folklore". I think it was Heckler that set me straight.

Even so, I can't imagine it is mandatory in any case. I would worry about an organization where it would be that necessary.
