So you’re working on your surface model, and you are trying to get everything to match up nicely, usually to either G1 (tangent) continuity, or G2 (curvature) continuity.  You think things look pretty good, you join them all together, you run ShowEdges to see if your model has any naked edges……and then you use Zebra to check that your edges are continuous in the way you desire.  Which, frankly, I think is completely nuts.  Allow me to explain.
