Maybe this has been happening all along and I never noticed it before, but for some reason, when I modify a group (i.e., push/pull a side), the group axes don’t seem to update accordingly. Part of me is thinking that the axis origin should automatically reposition to the lower front corner, but it isn’t (anymore).
In this example I create a cube and group it. Then I explode the group, push the front in, and exit. The origin of the axes remains in its original position.
