Hi,
I want to draw the two curves in red exactly on the surface of the palm. I am trying to use the polyline but I dont see exact results. Is there any way to precisely draw to curves on the surface.

Have you tried projecting the red lines onto the hand using project? That should do the trick.

I see trhis result when I use project.
I just need one single curve.
