Who could help to develop this rb?

[iApple]

Hi All, I found a "Layer Face Camera" plugin, and it's useful. But it can only turn off "always face camera". Who could help to add Switch ON/OFF function? Thank you very much.

version:

Added Undo

module JF
def self.layer_face_camera
layers = Sketchup.active_model.layers
name = UI.inputbox(["Layer"], [layers[0].name], [layers.map{|l|l.name}.join("|")])
return unless name
Sketchup.active_model.start_operation("Layer Face Camera")
Sketchup.active_model.entities.each { |ent|
next unless ent.is_a? Sketchup::ComponentInstance
next unless ent.layer.name == name[0]
cdef = ent.definition
cdef.behavior.always_face_camera = false
}
Sketchup.active_model.commit_operation
end
end
