PC-DMIS 2022.1. Part has fairly conventional alignment (datum A plane, datum B circle projected onto datum A, datum C line to another circle). Features on interest are holes in different orientations. 40-50% of holes' FCF true positions read "error" on report window, both for size and position. Features' actual values all populate, whether LSQ or max inscribed calculations are used. If I add legacy dimensions (with or without ASME-correct alignment), results populate fine.
BFRE; it's not the datums, since many of the FCF dimensions work fine. In fact, simply re-running the program, makes different FCFLOCs fail.
The specific error is "Datum A does not contain any features"; I would think that would make any FCF dimension with datum A fail to calculate, not just some.
I just had this happen to me but It was because I had a composite control frame that was not a feature of pattern so it errored out BUT... every fcf that was attached to the same datums structure (SIM TOL) was also in error because of the sim tol. hope that makes sense.
