Grasshopper Move with plane xy

Hi,

i need your help. I have a import for Rhino i cant rotate or move because i need the same export position. In rhino i changed the plane and so on…

Now i ref. to grasshopper and constructed the plane. It works well and the plane is horiz to my working place.
The problem is when i move a point etc the x y coordinates are not linked to the plane. this means that there is always an oblique displacement. how can i always link the vectors of displacements to the plane?

Thank you

Have a look at Point Oriented component, and if it fails :
