Feature control frames on metric prints

[LRRP_Ranger]

I am seeing a lot of metric prints that have other than the standard GD&T symols in the feature control frames and dimension call outs. Examples: A "r" in the feature control frame. I take it to mean the same as concentricity but not really sure. An "n" in front of a diameter call out. Is there a web sight I can go to that would explain these and others.

You can get help here, however your descriptions are vague..

Post an image of the features control frame in question (Tolerance Frame) and we'll take a look.

It might just be a translation error -- such as when AutoCad dwg or other format is converted to a PDF, etc.

That's probably what is going on. The translation was done without the fonts embedded into the PDF file as well as the op does not have the specific fonts on their computer.
