Has anyone seen a FCF like this? Was wondering if it is a universal thing or if it's customer specific. I think I might understand what it's asking, but I'm not sure how to input that into PC DMIS. A and B in the FCF are points on either end of a tube.
This A-B callout creates a common center line between to concentric diameters. What is Datum B? However, what I do not understand is how the FCF calls out MMB on Datum A when it clearly is a reference (no tolerance, unless the diameter size is somewhere else on the print). Plus, the FCF is on A, then calls itself back to itself.
