I've created a model of an octagonal gazebo by creating objects then using "Add Collection Instance" to duplicate objects and then rotating. The creation went great until I went to move the entire gazebo. For the life of me, I can't figure it out. Is there a way to move the entire model including original objects and instances? Here is a link to a basic blend file depicting what I did with a cube duplicated and rotated.
Any help would be appreciated.
