Material Take-Off by layers

[pingpink]

I'm trying to do a material take-off for the building project.

I have provided 4 web dialogs to extract data of aluminium , glass , panel ,and cap.

My problem is that when I select all model , the codes can not differentiate each type of layer selection. For example , web dialog of aluminium report should select only groups or components in a layer " Aluminium " , not combine with other layers. How can I write a condition of model selection in a specific name ?

selection.each { |s|
      
      is_group = s.is_a? Sketchup;;Group
      is_component = s.is_a? Sketchup;;ComponentInstance
      
     
      if (is_component || is_group) && s.layer.visible?

       layers = model.layers
	       new_layer = layers.add "Aluminium"
}

if s.layer.name == "Aluminum"

Wow ! I changed the codes and it can analyze the layers.

Thank you very very much , Dan !!

 selection.each { |s|
      
      is_group = s.is_a? Sketchup;;Group
      is_component = s.is_a? Sketchup;;ComponentInstance

		if s.layer.name == "Aluminium"
