Hello Matt
One of the designers found it on an older drawing that is being updated.
I've passed on the information about specifying the standard, since the drawing shows a different ISO standard, and it appears that the change is being processed.
Thanks to all that have helped.
Hello
Could anyone tell me what this symbol means?
It is on a drawing of a stamped metal part. Not pointed at any specific area, just in the general notes section.
Much appreciated.
