      Maybe Jim's construction line tool is of help: http://sketchuptips.blogspot.com/2008/02/plugin-construction-line-tool.html
      Have a look.

      As for SketchUp plguin writing in general:
      You will find many useful links in this thread: http://forums.sketchucation.com/viewtopic.php?f=180&t=10142
      It's worth noting that all plugins share the same environment, so it's important to learn how namespaces (modules and classes) works in Ruby - and use them. Otherwise you might end up with conflicts with other plugins.
      And a big no-no is overriding basic Ruby and SketchUp methods. Then you will most likely break other people's scripts.

        Try this... take the 'linetool.rb' code and copy it - make a new tool class named 'HiddenLineTool' say...
        and used that wherever 'LineTool' used to appear in the text, and also make a new def linetool >> def hiddenlinetool etc...
        Find the line of code that creates the geometry - it reads view.model.entities.add_line(p1,p2)
        and adjust it so it reads myline=view.model.entities.add_line(p1,p2)
        and insert a new line of code immediately beneath that that reads myline.hidden=true
        Now when you draw the line it'll automatically become a 'hidden' line - I suggest that you have 'Hidden Geometry' switched 'on' whilst using this tool, otherwise you could get very confused...

        Note also that you could make another version of it [GuideLineTool ?] to draw a guide-line (cline) by changing that one line to view.model.entities.add_cline(p1,p2) instead

            Get a better editor than Notepad. Get one that provides syntax highlighting - makes reading the code much easier.
            I use Notepad++ http://notepad-plus-plus.org/ - free app with a support for a wide range of languages.

              thanks a lot!
              well, I started off by looking at the code and I'm starting to get an idea of how things work.
              i edited the linetool file and changed the class to 'hiddenlinetool', etc...
              and added the line TIG wrote, however, I get an error:

              class/module name must be CONSTANT

              with a referring to this line:

              class hiddenlinetool

              ideas?

                Yes - constants in Ruby must start with capital letters.

                  The class would be HiddenLineTool
                  but the shortcut def hiddenlinetool...

                      To test type hiddenlinetool into the Ruby Console.
                      Later on when it's debugged to make a 'Plugins' Menu item use this code at the end - outside of the class etc

                      
                      if not file_loaded?(File.basename(__FILE__))
                        ### make command
                        cmd=UI;;Command.new("Draw Hidden Line"){hiddenlinetool}
                        cmd.status_bar_text="Draws a line and immediately hides it..."
                        ### menu
                        UI.menu("Plugins").add_item(cmd)
                        file_loaded(File.basename(__FILE__))
                      end#if
                      
                      

                      To put the tool into the 'Draw' menu instead, you just change 'Plugins' to 'Draw'.....
