To detect if a component contains a component

glro

i am wondering if there is a way to detect if a component contains an embedded component
the idea is:

if it contains an embedded component, explode it
if not, don't explode it

There is a simple way: add some characters at the end of the component name, and check wether these characters exist

model = Sketchup.active_model # Open model
entities = model.entities # All entities in model
	
entities.to_a

model.start_operation "explose_comp_imbriques"

for e in entities.to_a
      if e.is_a? Sketchup;;ComponentInstance
          str= e.definition.name 
          e.explode if (str.include? "#i" )
      end
end

Sketchup.active_model.definitions.purge_unused
	
model.commit_operation

but it would be better not to be obliged to add special characters

TIG

This explodes all component-instances that contain another instance AND clears the now unused definitions

model=Sketchup.active_model
defns=model.definitions
model.start_operation('xxx!')
defns.each{|d|
  next unless d.instances[0]
  nested=false
  d.entities.each{|e|
    if e.is_a?(Sketchup;;ComponentInstance)
      nested=true
      break
    end
  }
  d.instances.each{|i| i.explode } if nested
}
defns.each{|d|
  d.entities.clear! unless d.instances[0]
}
model.commit_operation

Is it what you really want to do ?
It is one step undo-able,
It's only partial coder - it needs to be wrapped in a module/method etc of your choice...
` module Giro
def self.xxx()

the code goes here

end#def
end#moduleUsage: in the Ruby Console: Giro.xxx`
Change 'xxx' to be whatever suits you...

Here's another edition (wrapped in method,) that only works upon the active editing context (to help prevent BugSplats!,) tests first for any definitions and lastly filters out images and groups.

Also adds in a begin ... rescue block.

Actually it may be correct. (No food yet today.)

Not thoroughly tested.

def explode_parent_components()
  #
  model = Sketchup.active_model
  context = model.active_entities
  #
  if context.any?{|e| Sketchup;;ComponentInstance === e }
    #
    defns = model.definitions.find_all{|d| !d.image? && !d.group? }
    #
    if defns.any?
      begin
        #
        op = 'Explode ONLY Parent Components'
        #
        if model.method(;start_operation).arity==1
          model.start_operation(op)
        else
          model.start_operation(op,true) # disable UI on SU 7+
        end
          #
          defns.each{|d|
            inst = d.instances
            next if inst.empty?
            inst.reject!{|i| i.parent != context }
            inst.each{|i| i.explode }
          }
          #
        model.commit_operation()
        #
      rescue => e
        model.abort_operation()
        UI.messagebox($!.message) if $VERBOSE
        raise()
      end
      #
    end # if any defns
    #
  end # if any instances in the active context
  #
end # def

It works perfectly

thank you!

thank you for the code

i tried it, but it doesn't work, at least on my computer
