Google Sketchupのデータのダンプ (Proof of Concept)

Ruby

C:\Program Files\Google\Google SketchUp 6\Plugins\ に以下のRubyスクリプトを nk_dump.rb として保存し，さらに C:\Program Files\Google\Google SketchUp 6\Tools\sketchup.rb を Plugins\ にコピーする．

require "sketchup.rb"

unless file_loaded?("nk_dump.rb")

  def nk_dump
    m = Sketchup.active_model
    File.open("#{m.title}.dat", "w") {|f|
      m.active_entities.each{|e|
        case e
        when Sketchup::Edge
          f.print("Edge: ")
	  f.puts(e.start.position.to_s + "--" + e.end.position.to_s)
        when Sketchup::Face
          f.print("Face: ")
          f.puts(e.vertices.map{|v| v.position.to_s + "--" }.join )
	else
          f.print("unsupported: ")
	  f.puts(e.inspect)
        end
      }
    }
  end

  tools = $suStrings.GetString("Tools")
  add_separator_to_menu(tools)
  UI.menu(tools).add_item($suStrings.GetString("nk_dump")) { nk_dump }

  file_loaded("nk_dump.rb")
end

こういう立体図形（くぼみ付きの，1辺1インチの立方体）を作ってから

「ツール」メニューに新設された "nk_dump" をクリックするとこういうデータが（同じフォルダに，拡張子 .dat で）書き出される：

これで有限要素法もへっちゃら！（ぇー
