z dimension
i have a dimension on a drawing called out as "z 8", it points to the edge of the part. this is on a part that is protruding from the inside of a cylinder. any idea what this means?
check out our whitepaper library.
is the part tapered? the lowercase z translates into a taper symbol when the aigdt font is used.

it doesn't appear to be. although it could be a taper between the id of the cylinder and the lug. the lug is a tab on the inside on the unit about 4" wide by 1" think. the callout is pointing to the line where the lug meets the id.
i will check out the taper symbols. you may be on to something. thanks.
