      Hi all,I want to get the Group object that contains the selected objects.
      such as:

      
      First I select a Group
          Sketchup.active_model.selection[0]    =>  <Sketchup;;Group;0xb79eb20>
      I open it ,and ,select an edge
          Sketchup.active_model.selection[0]    =>  <Sketchup;;Edge;0xb79ea48>
      Now I want to get the Group object contains '<Sketchup;;Edge;0xb79ea48>' ,that should be '<Sketchup;;Group;0xb79eb20>'.Using 'parent' methods,it can't work at all.
          Sketchup.active_model.selection[0].parent =>  #<Sketchup;;ComponentDefinition;0xb79e958>
      
      

      Please help me.

        So far so good, you have the ComponentDefinintion. Let's say you set it to 'cdef', then
        cdef.instances[0] will return the group you want - there's only one instance of a group's component-definition - I know it's convoluted !!!

        NOW you have the parent of the edge... = the group ?
