Problem with component definitions saved, has a non-default scale!

Hi all!
I use add_instance method with a transform parameter created before as below. But it has problem with “component definitions” saved as “has a non-default scale”, specifically everything works correctly till Redraw operation is performed, rotate value are back to default. Please help me deal with this problem. tks!

        mod = Sketchup.active_model
        ent = mod.entities
        sel = mod.selection
        defs = mod.definitions
        @comp_def = defs.load(@skp)
        re = sel[0]

        dsx_y = re.bounds.width  / @comp_def.bounds.width
        dsy_y = re.bounds.height / @comp_def.bounds.height
        dsz_y = re.bounds.depth  / @comp_def.bounds.depth
        sc_tr_y = Geom::Transformation.scaling( dsx_y, dsy_y, dsz_y)

        dsx_x = re.bounds.height  / @comp_def.bounds.width
        dsy_x = re.bounds.width / @comp_def.bounds.height
        dsz_x = re.bounds.depth  / @comp_def.bounds.depth
        sc_tr_x = Geom::Transformation.scaling( dsx_x, dsy_x, dsz_x)

        if 135<=angle_cam_corner_ent(re) && angle_cam_corner_ent(re)<225
          p_tr = Geom::Transformation.new(re.bounds.corner(1))
          rot_tr = Geom::Transformation.rotation(@comp_def.bounds.corner(0), Geom::Vector3d.new(0, 0, 1), 90.degrees)
          sc_tr = sc_tr_x
        elsif 225<=angle_cam_corner_ent(re) && angle_cam_corner_ent(re)<315
          p_tr = Geom::Transformation.new(re.bounds.corner(3))
          rot_tr = Geom::Transformation.rotation(@comp_def.bounds.corner(0), Geom::Vector3d.new(0, 0, 1), 180.degrees)
          sc_tr = sc_tr_y
        elsif 45<=angle_cam_corner_ent(re) && angle_cam_corner_ent(re)<135
          p_tr = Geom::Transformation.new(re.bounds.corner(0))
          rot_tr = Geom::Transformation.rotation(@comp_def.bounds.corner(0), Geom::Vector3d.new(0, 0, 1), 0.degrees)
          sc_tr = sc_tr_y
        else
          p_tr = Geom::Transformation.new(re.bounds.corner(2))
          rot_tr = Geom::Transformation.rotation(@comp_def.bounds.corner(0), Geom::Vector3d.new(0, 0, 1), 270.degrees)
          sc_tr = sc_tr_x  
        end
        trans = p_tr * rot_tr * sc_tr
 
        new_instance = ent.add_instance(@comp_def, trans)
        make_unique_comp(new_instance)
        re.erase!
        mod.active_path = nil
        sel.add(new_instance)
        Sketchup.active_model.selection.grep(Sketchup::ComponentInstance).each do |s|
             $dc_observers.get_latest_class.redraw_with_undo(s)
        end

      def angle_cam_corner_ent(e)
        mod = Sketchup.active_model
        cam = mod.active_view.camera
        cam_point = cam.eye
        cam_vec_ent = [cam_point[0], cam_point[1], 0].vector_to(e.bounds.corner(0))
        if cam_point[1]<0
          angle = cam_vec_ent.angle_between(X_AXIS)/Math::PI*180
        elsif cam_point[1]>0
          angle = 360 - cam_vec_ent.angle_between(X_AXIS)/Math::PI*180
        end
      end

If you place a new instance of the component manually from the Components panel, you should be able to see what size the component “actually” has. You can also right click one of those your script has placed and select Reset Scale. This size should math that of a saved out component.
