Expressions - Absolute position in the space


I was wondering if anyone of you knows how can I write the expression for determine the absolute position of a peg in the space.
Absolute position= position of the peg relative to the field.
The peg is linked/parent to another peg.

Right now the expression I have is:

var Posy = column(“Ho_PV-P_Pos_y”);

but I need to find out the coordinate absolute not relative (if you guys get what I mean).


I’m curious about this too.

I would also like to know
