The Tolerance of Profile produces strange value with two Datums.
Look at the measures FCFPROF4 and FCFPROF7 (PDF file).
PC-DMIS it allows to insert two Datums. I have used two Datums (circles A and B). Is this procedure correct?
The profile with two datums is getting a big deviation caused by "the secondary datum feature is approximately parallel to the primary datum feature , and create an unreliable alignment with a big rotation angle".
