      Let's put this another way... 😕
      What are you trying to do?
      [In words, not 'code'...]
      I deduce that it's to find if something is an instance and then check that instance.definition.name against a 'text' pattern ??

      If so it is much easier than you are making it...

        thx ! I'll try this tomorrow

        Hmmm let me explain, it's little bit difficult for me to explain that in English

        I want to create a plugin which count every components and groups in the design.
        With this plugin, you can calculate the texture you need for a group or component (Tomorrow, I will take screenshot to show you my work (but it's in French...)

        For example, I have a component called "Wood Table" (definition name) and you call it "Table 200x300"
        My plugin will count how many tables I have on design and how much texture of Wood I apply on all tables.
        If I don't the plugin calculate the texture (I hope you understand this sentence 😄 ), I have to put "_" (character n° 95 in ASCII TABLE) and the plugin ignore the Table. (ex: "Table 200x300 --> "_Table 200x300")
        But in my case, it only work for the name of groups and component, but I want to add the case for component-name. How should I do ?

        Thanks a lot to everyone ! 😉

          Instead of iterating entities to get all instances and then find their definitions, why not iterate the definitions list to get their instances ?

            I just beginning ruby for sketchup less than 7 days, I don't know anything... 😞

            I just modified the code from someone.
            Tomorrow, I will show you exactly what i'm trying to do.
            I don't have sketchup in that computer

              I wrote a summary about instances and definitions in SketchUp: http://www.thomthom.net/thoughts/2012/02/definitions-and-instances-in-sketchup/
              Hope it might help.

                  My plugin :

                  http://img32.imageshack.us/img32/4237/71551261.png

                  My group has a name : "GroupWood"
                  2 same components : 1 with name "Bench1" and the 2nd without name.
                  The plugin will retrive all informations and put that in table in HTML webpage.
                  In component section, if the name of component is empty, the plugin retrive definition name. If it has a name, it takes the name.

                  If I put "" before the name of the group or name of component, the plugin ignore the texture of them.
                  But if I put "
                  " before the definition name, it doesn't work. I would like to add this third condition my program.

                  Someone can help me ? 😄

                    You are not making this easy by hiding your code from use and then expecting us to 'fix' it.
                    Here is how I would check some text [refernced as 'str'] to see it it starts with a ''
                    str=~/^_/
                    If there's no match it returns 'nil' if there's a match you get 0.
                    So to test a 'name' against the pattern just use
                    ` if name=~/^
                    /

                    do something

                    endTest the group.name, instance.nameand instance.definition.name` in turn 😕

                        Something like

                        if (chose.is_a?(Sketchup;;ComponentInstance) && chose.definition.name=~/^_/ ) || (chose.name=~/^_/)
                          chose.explode
                          nb += 1
                          trouve = true
                        end
                        

                        😕

                          it didn"t work ...

                          I will try something else. Another way

                          I practice in how I get the name of definition through a table, and then I will associate that with my code

                            If you have a reference to the instance you can easily get its definition, from which you can easily get the name of that.
                            I don't see where the difficulty is ?
                            You just need to add some extra tests to your code of instances... in more than one place - my example was how to get the initial name to use...

                              Yeah but i'm beginning ! so I have to learn what is exactly the difference between componentdefinition and componentinstance, it's hard for me !

                              Every document is written in english, I have to translate some words and then i have to understand each specific vocabulary of sketchup ... (in less than 1 week !)

                              I have to go easily on that !! 😄

                              I will continue monday because I have no tools to continue at home

                              thx TIG! 👍

                                Hi everyone !

                                I have found how to correct my code !! 😄

                                It's was just an error of algorithm.

                                At first time I had this condition :

                                chose.name[0] != 95
                                

                                And I would like to have this :

                                chose.name[0] != 95 || chose.definition.name[0] != 95
                                

                                but it doesn't work ...

                                The solution is :

                                chose.name[0] != 95 && chose.definition.name[0] != 95
                                

                                As I said, I'm beginning !

                                Thanks to all! especially TIG
