In the picture, I built a multi-storey model.
I am going to try to place components periodically.
At the beginning I grabbed the height of each floor and gave the coordinates.
And use the List.GetItemAtIndex node to grab points and place the component.
But I found that the output of index=0 and index=1 will only be placed in the index=0 position.
Has anyone ever had this happen?

Can you share the rvt and dyn files? Hard to diagnose the cause without something to play with.
