Typ. Dimension

I remember a long time ago, there was a discussion on Typ. dimensions, but I cant seem to find it.

I just had a run of new parts and the print is LOADED with typ. dimensions. Normally, I dont even bubble up the typ dimensions, but with the number of them on this print, I am wondering what I should do.

Are you referring to dimensions that are noted with "TYP" indicating "typical"?
Why would you not bubble these?
"REF" dimensions can usually be ignored, buy not "typ".

I have never bubbled them. My first quality manager that trained me that these were just like reference dims. I have never had a customer ask for them on all the initial layouts that I have completed. ASME Y14.5-1994 does not recognize the callout.

BTW.. TYP is what I am referring to.

"TYP" is usually used for multiple dimensions as a way to avoid having dimensions all over the print cluttering it up.
It is used for things like fillet or corner radii and wall thickness, etc.
They need to be measured just like any other dimension.
