So, in this test I made a white square just to use as a reference point. I inserted a 12"x12" stick of truss and hung it at 90 degrees (vertical). When in top/plan view, it stays where I put it, when I switch to do a fly over or change the view in 3d, it moves about a foot to the right. I also cannot rotate it around on the base as if i wanted to turn it at a 45 degree angle.
