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.
What I'd do is measure Datum A, measure Datum B, smash the PC into tiny pieces with a hammer, then go to the pub and seriously consider my career choices.
