Hi. Can I help you ?

I would like to know how to copy a hole-type component (for carpentry work) into an MDF-type component. The basic idea is: I have a hole-type component that, when applied to a surface, makes the cutout correctly. I copy it from the environment and paste it into the MDF component. However, when I do this, it does not cut via script. I have to go inside the MDF component and move the hole so that it makes the cutout. I would like to know if my scripting approach is wrong, if there is another easier way. I would like your help.

mod = Sketchup.active_model # Open model
ent = mod.entities # All entities in model
sel = mod.selection # Current selection

def find_subentity_by_name(parent_instance, subentity_name)
  #p parent_instance.definition.name
  if parent_instance.is_a?(Sketchup::ComponentInstance)
    p "é uma instância"
    parent_instance.definition.entities.each do |entity|
      if entity.is_a?(Sketchup::ComponentInstance)
        if entity.definition.name == subentity_name
          return entity
        end
        subentity = find_subentity_by_name(entity, subentity_name)
        return subentity if subentity  # Retorna se encontrado.
      end
    end
  end
  return nil
end

  component_definition = component_instance.definition
  target_entities = target_instance.definition.entities

thank you.
this looks very useful indeed.
