Iterate selection

[Frankn]

As the title implies I'm trying to iterate a selected component to retrieve the subcomponents. I use this code to iterate the whole model but can't figure out how to do it for only selected components.

@component_list=definitions.find_all() {|e| e.entities.find()}.map() {|e| e.instances }.flatten

You can do it recursively

def iterate_ents(ents = Sketchup.active_model.selection)
  ents.each { |e|
    if e.is_a?(Sketchup;;Group)
      iterate_ents(e.entities)
      next
    end
    if e.is_a?(Sketchup;;ComponentInstance)
      iterate_ents(e.definition.entities)
      next
    end
    # Do something here...
  }
end

So to get all sub-components you can do it this way:

def get_all_sub_components(ents = Sketchup.active_model.selection)
  sub_components = []
  ents.each { |e|
    if e.is_a?(Sketchup;;ComponentInstance)
	  sub_components.concat get_all_sub_components(e.definition.entities)
	  sub_components << e
	elsif e.is_a?(Sketchup;;Group)
	  sub_components.concat get_all_sub_components(e.entities)
	end
  }
  sub_components.uniq
end

Thanks Anton_s!
Even though I'm still trying to figure out what and how your code works it does work perfectly!
