Snap not snapping :O

Hi,
also following this .gif i tried the same but snap is not snapping vertex of curve on vertex of mesh yet. Tried shift, control, alt, but nothing. Manual also doesn’t pull out on “snap” search.

Here is my screen


Please supply demo blend file for review

thx, just got it working. Reason was that the object i was trying to snap to was scaled to 0 in y.
