Curvy path to face

Hi there! I’m trying to make a display window for my school project. I want to do a wavy ceiling detail. The problem is i cant align this wavy line to curvy face. Can make this in sketchup? I hope i explain myself and my problem. I’ll add the model of things that ive been talking about. Im trying to do a curvy line on a curvy face. Thanks already!
