I want to chagne group axis like pic (left → right)

and I used this method(in following code) but didn’t work

Can you help me for it?

 edge = group2.entities.add_line(start_point, end_point)
        xaxis = end_point.vector_to(start_point)
        zaxis = end_point.vector_to(start_point) * yaxis
        yaxis = end_point.vector_to(start_point) * zaxis
        transform = Geom::Transformation.axes(start_point, xaxis, yaxis, zaxis)
        my_group = group2.definition
        my_group.instances.each{ | instance | instance.transform!(transform)}
        my_group.entities.transform_entities(transform.inverse, my_group.entities.to_a)

to move group axes in ruby, first, you move the group to a new point, you go to group edit mode, and move all entities in the group to its original place. When you move and rotate a group its Axes also move and rotate, when you move and rotate back entities of a group its axes not move and rotate. Don’t try to move axes directly.
