Layouts don’t actually have a scale.
The drawings you place on the layout do have a scale.
That is why the scale bar needs to be part of the drawing title.
Placing a separate object in the layout will have no relation to the drawing.
You could however place the object in the Archicad view.
Then it can read the scale of that view (I do this all the time – never use drawing titles).
That would work unless you are then re-scaling the view in the layout (which in my opinion you shouldn’t be doing).
