Back again,
I think that the reported behavior is somehow related to this Entities.add_group causes Bugsplat! - #6 by jim_foltz.
When trying to use the method add_group(entities) like so some_container.entities.add_group(an_array_of_some_entities) when what is to be added into the new group is NOT already in the model.active_entities then the group is created under the Sketchup.active_model.entities
This is really tricky and I dont get how to perform the @TIG solution explained in his post :
If what is to be added into the new group is NOT already in the
model.active_entities, then use
group = some_entities.add_group()
then use add entities togroup.entitiesafterwards…
I can’t find any way to perform that, it’s like reparenting entities into an another group what is impossible in Sketchup. I’m I wrong ?
More over, problem still existing in SU2019…
