Question about a tricky tolerance callout on a recent assembly drawing
I was detailing a bracket for a machine frame last week, and the callout for a true position tolerance on a set of four bolt holes just would not work. The software kept flagging it as an invalid datum reference. I spent close to three hours checking the feature control frame, the datum features, and the order of precedence. Turns out I had accidentally selected a datum axis from a different, unrelated part that was still open in another file. Once I closed that extra file and rebuilt the callout from scratch, it worked perfectly. Has anyone else had a similar issue with cross-file references causing trouble?
