Another thing I noticed. You can have (2) Centered Constraints, but not (2) Coincident Constraints.
Going back an re-evaluating the work from the morning, i had three constraints, one set of surfaces and two sets of holes alignments. The first set was the surfaces, the next one was centered, the third was coincident. When I changed the 2nd constraint from centered to coincident, the third automatically changed from coincident to oriented. Didn't see that coming.
