I need a position object behaving by the position of other 2 objects
something like this:

Object 1 (child)
Object 2 - Object 3 (parents)

i need (Object 1_X position) = (Object 2_X position) + (Object 3_X position)

I tried wiring Obj1.x pos with obj2.x pos and in the expressions field
define obj2.x+obj3.x and it works but only when i move obj2 because is
where obj1 is wired, but if i move obj3 nothing happens until i move obj2
again so max refreshes obj1 pos state.
I need the updated Obj2.x pos when i move Obj1 or Obj2 but can't wire
2 parameters with a same parameter.

I'm not sure if i am clear because my english sucks a lot, but i hope someone
can help me with this one.

TIA!!

i think what i need here is a 'refresh' command or something like that

because if i keyframe a few pos it works ok, but it doesn't
when i am interacting with it.

any clue?

I think i found the solution: DependsOn ;)

It refreshes when doing interactive mods.
