Andrew,
I believe you are correct in that the GD&T is applied incorrectly for the part the lid is fitted to.
It's obvious to everyone involved in making the parts that the lid has to fit down inside the pocket, and they will machine accordingly.
Thanks for everyone's help.
Thanks greenimi.
The attached file is of the mating part, a lid which fits just inside the pocket. It appears to me that the GD&T on the pocket was applied incorrectly.https://files.engineering.com/getfile.aspx?folder=35a4e5ff-f1cc-4466-b369-c73d536485d1&file=lid.jpg
The attached file is a screenshot of one of our engineering drawings.
The feature is an internal pocket. Question is regarding the .025 callout behind the Unilateral symbol.
What does it mean in this application...
