here the file :)
so exact the same that the first post!

It's not easy to find speedy the good orientation :)

And I am not abble to slide the object on the single curve on only one move!
It's turns on the middle or along the path!
and it have not the same orientation than the object on the top of the surface!

It's ok for object on the top curve surface, i have killed the original curve after it move
Base of the object is at its middle front bottom

And of course I want perpendicular position along the curve
