This might be hard to explain without showing a print. Wish I could, but that's a no-no since they're confidential documents and all. Anyway, let's say I have an older print with holes that are dimensioned to each other, rather than to a datum or to a common origin point. They also have a true position call out. As I understand it, you can select either "current alignment" or "datum reference frame" when creating a position dimension for the holes. If I was required to report the holes with the nominal dimensions from the print, rather than from the datum reference frame, say for PPAP purposes, does that mean I would have to create an alignment for every single hole to get them to report exactly as the print dimensions them? Or is there a more efficient way to do that? I hope I'm making sense. I'm still pretty new to this.
Unfortunately some customers want to see the basic dimension measurements, in that case you usually need to create alignments or report hole to hole distances. I always add a note to the report, something like:
THE FOLLOWING BASIC DIMENSIONS AND TOLERANCES ARE FOR QC AND ENGINEERING REFERENCE ONLY, OR CUSTOMER REQUIEMENT.
