Seems like once you create an intersection curve, it doesn't change if the solid body changes.  Is there any way to refresh an intersection curve?  I know that I can just do it over, but often I base sketches off of intersection curves...like maybe doing a sweep cut that has an intersection curve as the profile.  If I make a change to a part, and the intersection curve doesn't change, then that step fails.  I could live with that if there was a way to open it and have it refresh...
