The Reference Curve by Intersection command creates a reference curve on the selected plate system by defining the landing curve as the intersection of the selected plate system and a grid plane.
You can control the boundaries of the reference curve by selecting a plate system or reference curve that intersects the landing curve. If you do not define boundaries, the software uses the landing curve ends as the reference curve boundaries. The reference curve must end at a plate system boundary or at another reference curve on the same plate system. The reference curve can cross an opening in the plate system.
