Need help understanding true position. Earlier this year my company laid off the majority of our workforce, so now the rest of us are trying to help out other areas the best we can when the need arises. Just so happens that we no longer have an inspector, so I have been asked to help fill in. I have done a little bit of inspection in the past (20 years ago), but I just can't seem to understand what I'm supposed to do measurement wise when there is a true position called out in a feature control frame on a drawing. I've read ANSI Y14.5 and I know the definitions, but applying what I've read for some reason is not sinking in. For example, just a basic feature control frame that shows the true position symbol, then a number, let's say .002 and then has a datum feature "A". What am I going to be measuring?
