  I am sorry, I do not fully understand.

  So you want a clip of all shapes inside that area? There is a specific method for that: Layout#clip

  Hi Matthias,
  checked with the notice of clip , look like it is what I need , but could you please pass me a sample?
  as below , I want to make all the pattern within the bbox area into a cell , and make it named "CELL_IO".
  in the document , I saw the description of clip , but I can't get the point for how to using that....

  Description: Clips the given cell by the given rectangle and produce a new cell with the clip
  cell:
  The cell index of the cell to clip
  box:
  The clip box in database units
  Returns:
  The index of the new cell

  main_window = RBA::Application::instance.main_window
  layout = RBA::CellView::active.layout
  layout_view = main_window.current_view
  layoutView = RBA::Application::instance.main_window.current_view.active_cellview.cell
  cells_to_delete = []
  x1=-9500.00000*1000  ##change dbu
  x2=7000.00000*1000  ##change dbu
  y1=-146000.00000*1000  ##change dbu
  y2=-144200.00000*1000  ##change dbu
  iter = layoutView.clip(layoutView,RBA::Box::new(x1, y1, x2, y2))

  Here is some code I found in an older discussion. It produces a clip from the rectangle -1mm, -1mm to +1mm, +1mm (for database unit 0.001µm). Please note that the rectangle coordinates must be given in database units:

  layout = RBA::CellView::active.layout
  
  clip_rect = RBA::Box::new(-1000000, -1000000, 1000000, 1000000)
  clip_cell = layout.clip(layout.cell("TOP").cell_index, clip_rect)
  options = RBA::SaveLayoutOptions.new
  options.add_cell(clip_cell)
  layout.write("clip.gds", false, options)

  Hi Matthas,
  After check , clip should not what the function I need , or maybe I have some miss for the script.
  As below , I using begin_shapes_rec_overlapping... to get what the pattern in special layer and where the place in the BBox.
  that is what the step1 ,
  in step 2 , I want to make these pattern and make it named "pattern".
  but....Look like I still need your help to learn how to process the pattern "pattern_item".

  layout = RBA::CellView::active.layout
  ly = RBA::Application::instance.main_window.current_view.active_cellview.layout
  layoutView = RBA::Application::instance.main_window.current_view.active_cellview.cell
  x1=-12596.05000*1000
  x2=12596.05000*1000
  y1=-14673.14500*1000
  y2=14673.14500*1000
  l1 = layout.layer(75,0)
  pattern_item = layoutView.begin_shapes_rec_overlapping(l1,RBA::Box::new(x1, y1, x2, y2)) 
  
  while !pattern_item.at_end?
    if pattern_item.shape.renders_polygon?
      polygon =pattern_item.shape.polygon.transformed(pattern_item.itrans)
      puts "In cell #{pattern_item.cell.name}: " + polygon.to_s
    end
    iter.next
  end
  

  #

  in this code , the function is what I want to do....
  I can copy all the shape (in layer 154,1) , change layer and copy pattern int cell.
  but I can't choose the pattern by BBox area...

  layout = RBA::CellView::active.layout
  ####create shape into cell and 
  
  bumplayer=input(154,1)
  bumppadlayer=94
  bumppadpur=0
  workcell="pattern"
  if  !layout.has_cell?(workcell) then
  layout.create_cell(workcell)
  end
  
  l1 = layout.layer(bumppadlayer,bumppadpur)
  top = layout.cell(workcell)
  bumplayer.data.each do |poly|
  top.shapes(l1).insert(RBA::Polygon::new(poly))
  end
  
  placeme = source.layout.cell(workcell) 
  source.cell_obj.insert(RBA::CellInstArray::new(placeme.cell_index, RBA::Trans::new(0,0)))

  This is a DRC script, isn't it? This is a DRC statement:

  bumplayer=input(154,1)
  

  If you're in DRC, why not just doing:

  x1=-12596.05000
  x2=12596.05000
  y1=-14673.14500
  y2=14673.14500
  
  clip(x1, y1, x2, y2)
  
  input(154, 1).output(94, 0)
