Frame perp. to a Surface

Can anybody tell me how to add a frame in order to find the normal of the surface. I've used the evaluate surface component but the frames seems to be outside of the surface.
any ideas?
thanks

That center pt in 3d is not the same as the uv pt. Try the Surface CP component to get the uv parameter on the surface.
