    I'm afraid I don't know what it could be.

    You use the reference to the newly created group immaterially? Or is there code in between?
    Is there any code that converts groups to components?

      This won't happen unless the base classes have been interfered with - either within your code or some third-party code - OR your code makes the new group into a component before you try to get its entities.
      Can you supply more code/context etc...

        Hi

        I am checking the class of the add_group() return value immediately, no other code in-between.

        Thanks

          I think I saw another thread where unexpected entities was returned - think it was fixed by a reinstallation.

          Have you tried on another machine?

            Yes, I tried in two different machines. I also uninstalled Sketchup, download latest version and reinstalled but no luck

            Thanks

              If you use this line of code in the Ruby Console what do you get?
              tgroup=Sketchup.active_model.active_entities.add_group()
              It should return a reference to a Group, something like:
              #<Sketchup::Group:0x11379d24>
              Then
              tents=tgroup.entities
              It should return something like:
              #<Sketchup::Entities:0x112964ac>
              Now try something like:
              tents.add_cpoint([1,2,3])
              It should now add things to the group ?
              If it fails, then at which step??

                Hi

                I tried in Ruby console as suggested by you and it works without any issue. For that matter, If I have only this part of the code in a .rb file and load into Sketchup that also works. My problem comes up in my main program where some more rb files are loaded. Unfortunately those files are too many and inter-related, so now I am trying to separate them and load one by one to isolate the offending code.

                  Hi

                  This issue seems to be related to removing "Susan" definition. Please refer the following code, in this If I remove the code, which erases Susan, then the temp_group creation is success else it return ComponentInstance.
                  And also, I get this error only when I put this code in a rb file and put in "Plugin" directory , if I save the rb file in some other directory and load that file from Ruby console, I don't face this issue.

                  ` component_list = Sketchup.active_model.definitions
                  cm = component_list["Susan"]
                  if(cm != nil && cm.count_instances > 0)

                  If I comment out following line, it works

                  cm.instances.each { | entity | entity.erase! }
                  end
                  entity_list = Sketchup.active_model.entities
                  temp_group = entity_list.add_group
                  UI.messagebox("temp_group class: #{temp_group.class}\n")
                  temp_entity_list = temp_group.entities`

                  Thanks

                    Why are you working with a template that includes 'Susan' in the first place ??
                    That template is just an example - make your own to suit your needs...
                    If this is anything like a reusable script it needs to work with ANY skp...
                    ๐Ÿ˜’
                    Is this code inside at least a def xxx()...end method? [I'm not insisting on a module or a class... here]
                    If your script is loading just 'raw' code at startup it could well make a mess...

                      I second TIG's question why you're removing the Susan definition? Why is that essential for the plugin to work?
