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

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.

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

Hi

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

Hi

Thanks for the reply.

This code is part of bigger ruby code, I am not sure, where I am messing up. I created simple ruby file with above code and it works without any problem. I stop loading all other plugin that is not helping. Next I will isolate rest of my code to see why it is happening, in case you have any pointers to look for please let me know.

BTW : My OS is Win 7, I hope it will not have any impact on this issue.

Hi

I am using Sketchup 8.0.14346. In my ruby code when I use add_group API Call, the returned object's class seems to be component instance as shown in the error message here.

model = Sketchup.active_model ent = model.entities tgp = ent.add_group temp_entity_list = tgp.entities
......
==> undefined method `entities' for #Sketchup::ComponentInstance:0x5269634

When I try the same code in Ruby console add_group return value class is "Group", this problem comes up only when I use this code in a script. Any help please ?

TIA
