Draw curve on surface command name

Why I can remember, there was something to draw curve on surface in rhino 4.

I can be totally wrong. Or may be i made any custom plugin to draw curve on surfaces earlier and now forgot it totally.

I am using Rhino 5 now.
Is there any command which can draw curve on curved surfaces?
Please let me know. Very urgent help needed.

Best wishes
