Column Dimensions

i already made the scribt in a new Revit File i didn’t try it in a real Project

I tried changing the reference as shown by you. But still the scripty doesnot work. I am getting the reference of dimension like this.

@GavinCrump
I was working with a script where I was trying to dimension the linked columns. It works perfectly fine with live Revit project. I was able to dimension all the columns or wall. But when try to modify the script using bimorphnodes to read linked element, script seems not working. Getting an error at node named dimension By Reference. Could anyone help to resolve this please.
