merge path

lukasc

Hi Matthias,

Would it be possible to add a feature to merge paths together? Namely, if I draw one path, I would like the ability to extend it (assuming the same widths). You already have a "merge" mode in the toolbar, but when we draw paths using the "merge" mode, they get converted to polygons.

Thank you
Lukas

Hi Lukas,

Maybe here is a script which does what you want: it will selected paths and join them by concatenating the segments. I guess handling of end and start extensions and redundant points is missing but it may serve as a staring point:

mw = RBA::Application::instance::main_window
view = mw.current_view

begin

  view.transaction("Merge paths")

  new_path = nil

  sel = view.object_selection
  new_sel = []
  to_delete = []

  sel.each do |s|
    if !s.is_cell_inst? && s.shape.is_valid? && s.shape.is_path?
      if !new_path
        new_path = s.shape.path
        new_sel << s
      else
        pts = []
        new_path.each_point { |p| pts << p }
        s.shape.path.each_point { |p| pts << p }
        new_path.points = pts
        s.shape.shapes.erase(s.shape)
      end
    end
  end

  if new_path
    new_sel[0].shape.path = new_path
  end
  view.object_selection = new_sel

ensure
  view.commit
end
