I would draw the curve on a proxy surface (parallel to the SubD) before using Pull command to place the curve on the SubD.

Hi -

What issue are you running into?
PersistentOnSrf and PersistentOnPolysurface work on SubD objects as well.

The proxy surface is temporary surface (object). It is made to make to make another, more important object. In this case, I would make proxy surface or proxy polysurface which is parallel to the SubD and close to the SubD.

If you draw the curve directly on the SubD using Object snap, the control points of the curve will be on the SubD, but the curve will not be on the SubD. (InterpCrv command will place the curve closer to the SubD than Curve command.)
