      concerning typename vs class:

      For, till now, unexplained reason when i change typename with class the results are different
      Script is a bit like this:

      x=entity.class (or entity.typename)
      if x=="Face"
      do something
      elsif x=="Group"
      do something
      elsif x=="ComponentInstance"
      do something
      else
      end
      

      When the type is "ComponentInstance" the results are not the same for class and typename.
      I need to check on this since the speed increase is huge

        .class returns a Class object - not a string.
        What causes the slow down is the string comparison - that's what you want to avoid.

        
        x=entity.class
        if x==Sketchup;;Face
          do something
        elsif x==Sketchup;;Group
          do something
        elsif x==Sketchup;;ComponentInstance
          do something
        else
        end
        
        

        or

        
        if entity.is_a?(Sketchup;;Face)
          do something
        elsif entity.is_a?(Sketchup;;Group)
          do something
        elsif entity.is_a?(Sketchup;;ComponentInstance)
          do something
        else
        end
        
        

        Update: fixed is_? to is_a?

          I'll check and let you know. When i use 'class' the correct conditions are entered but the result differs.
          I'll keep you posted if it changes with your scripts.

          Thx

                One thing I have noticed is that some code runs much slower with the outliner window open. Is there a way to close the window at the start of certain code execution, and then re-open it at the end?

                  Maybe...
                  but have you tried using Model.start_operation ?

                  see also abort_operation and commit_operation

                    UI.show_inspector "Outliner"
                    toggles it.
                    Shows it if it's closed
                    Rolls it up if it's shown
                    Unrolls it if it's rolled up

                    There's no way with the API to tell (now) what state it is in.

                      I think Jim made a Windows hack to toggle a rollup...

                      ### toggleWindows.rb - based on Jim's ideas - only for Windows...
                      ### 20090401 TIG
                      ### needs "win32api.so"
                      if [PLATFORM].grep(/mswin/)==[PLATFORM] and Sketchup.find_support_file("Win32API.so","Plugins/")
                      ### = a Windows machine
                        require 'Win32API.so'
                        def toggleRollUp(name)
                          findWindow = Win32API.new("user32.dll","FindWindow",['P','P'],'N')
                          pw=findWindow.call(0,name)
                          sendMessage = Win32API.new("user32.dll","SendMessage",['N','N','N','P'],'N')
                          sendMessage.call(pw,0x00a1,2,"")#WM_NCLBUTTONDOWN
                          sendMessage.call(pw,0x0202,0,"")#WM_LBUTTONUP
                        end
                        def isRolledUp(name)
                          findWindow = Win32API.new("user32.dll","FindWindow",['P','P'],'N')
                          getWindowRect= Win32API.new("user32.dll","GetWindowRect",['P','PP'],'N')
                          pw=findWindow.call(0,name)
                          data=Array.new.fill(0.chr,0..4*4).join
                          getWindowRect.call(pw,data);
                          rect=data.unpack("i*")
                          #if window height is less than 90 then the window is rolledup
                          return (rect[3]-rect[1])<90
                        end
                      end#if
                      

                      You add 'Outliner' to run it... test if rolled up, toggle roll up if not etc etc........

                        its nice but...
                        The windows have other language names in the loacalized versions.
                        The code needs updating. It needs to search by ID instead.
                        (Or have arrays of the Inspector captions in all the local versions.)

                        It also should be in the SKX forum, either as a UI module extended method (which would be half done, as it's only Win32,) or a SKX::GUI::WIN method.. or something

                          I only pass on Jim's hack... if you want to 'fix' it please do... It'd be better if the API had proper access to these anyway !

                            Dan, this is absolutely what I need. It is the updating of the UI that is slowing the calculation down. Having the outliner window open compounds the problem.

                              You are using .start_operation with the disable_ui flag, right?

                              Also, try to do as much as possible in bulk operations. Transform and erase in bulks. entities.erase_entities instead of entity.erase! etc.
                              Cache calculation results - Ruby is horribly slow in crunching numbers.
                              Often, methods that accepts Point3D objects can use Vertex objects as well - though the API docs doesn't mention this. If you are doing many iteration vertex.position will eat time. So try to feed the methods raw vertices instead.

                                Ooops.. just checked. The Outliner does not have an ID.
                                But Jim's system call 'may' work. The window object can have a different "name" than the text displayed on the caption bar.
                                Someone running a non-English version could test it and let us know.

                                    What I found most interesting in those test was that Vertex is a valid argument where the manual claims only Point3d. And passing the Vertex is faster than Vertex.position.

                                    Well i think you'll find this is a commonality of the API and the Docs is the fact that "those" who are creating the API and the Docs ARE NOT "those" who use it on a daily basis! πŸ˜‰

                                      Hi guys,

                                      I have just found out that converting String to Length directly is up to 13x slower in comparision to converting it to Float first and only then to Length...

                                      
                                      def string_to_length_conversion(iterations=100_000)

                                      		a = '5,0'.to_l

                                      		# convert to Float, then apply units (meters in this case) and set to Length
                                      		a = '5,0'.to_f.m.to_l

                                        That is useful to know. But that assumes one has a string with only a numeral.
                                        String.to_l will allow you to covert strings such as '20m' and '20mm'. With out any length unit indication in the string it will assume the length is in the unit of the current model.

                                          BUT remember that .to_l parses any 'units' text to work out the actual value into inches...
                                          So "1.0m".to_l >>> 39.3700787401575"
                                          or "1'".to_l >>> 12"
                                          BUT
                                          "1.0m".to_f.to_l >>> 1.0"
                                          and "1'".to_f.to_l >>> 1"
                                          therefore you may as well miss out the second method .to_l as
                                          "1.0m".to_f >>> 1.0
                                          and "1'".to_f >>> 1
                                          i.e. as a 'raw number'... AND 'raw numbers' are assumed to be in inches anyway == 1.0"...
                                          Also .to_l and .to_f work differently if there is no 'unit' suffix...
                                          If you have mm set as your current units then
                                          "1".to_l >>> 0.0393700787401575 (inches)
                                          but "1".to_f >>> [ruby:3h6c8mbs]1.0[/ruby:3h6c8mbs] (float/number),
                                          and with inches as the current units
                                          "1".to_l >>> [ruby:3h6c8mbs]1[/ruby:3h6c8mbs] (inch)
                                          SO if you have an input that might be in anything other than inches and might have units in its string you do need to use .to_l or you risk returning a wrong value... πŸ€“
