Replace a construction in a construction set

I am struggling to replace a construction in a construction set generated via openstudio-standard with a construction extracted from a reference model. I have based my code on this measure, but no success so far.

This is my attempt. First I get my wall construction from an existing model

wall_construction = ref_model.getConstructionByName(wall_construction_name).get

(The construction exists)

then i create a standard object and get its construction set with

bldg_def_const_set = standard.model_add_construction_set(model, climate_zone, building_type, nil, false)

Finally, I try to replace the construction for walls with

if bldg_def_const_set.is_initialized    
  # This is the overall construction set
  bldg_def_const_set = bldg_def_const_set.get
  # This is the exterior surfaces default construction set
  default_ext_surface_const_set = bldg_def_const_set.defaultExteriorSurfaceConstructions.get
  # And now we can assign the wall
  default_ext_surface_const_set.setWallConstruction(wall_construction.to_Construction.get) # Tried also with to_ConstructionBase as in the measure. 

  puts "SAP construction replaced the default construction!"
  puts "Success!"
  puts "Could not create default construction set for the building."

There is no error, but the new construction is not there.

I cannot understand what I am missing. Any idea?

wall_construction is still just in ref_model you need to clone it to model before you assign it. That would look something like this.

wall_construction = wall_construction.to_Construction.get
wall_construction_clone = wall_construction.clone(model).to_Construction.get

That makes sense. Thanks!
