big thanks @ TIG and thomthom. It works !!

@ thomthom : Yes, the group is in model.active_entites and i obtaining the group. This isn't my Problem. But i get over Sketchup.active_model.active_entities[0].entities[1].end.position or Sketchup.active_model.active_entities[0].entities[1].start.position the local position of a edge(Start- and End-Vertex) in the group , not the global position in the whole model ! But i need the global position

Hello everybody,

can somebody explain me, how i get the location of a group(In Sketchup.active_model) over a ruby script ? Currently, i get only the local position of the entities in the group(groups have a own axis of abscissas), but i need the global position. I hope, you-all understand my problem
