Hello! Anything created in Model Space will rotate with MVSETUP, including text, dimensions, lines, blocks, and XRefs. If text and dimensions are created in Layout/Paper Space, they won't rotate.
Starting at 3:20 in the video, you can type any angle you want when you get to the "Specify angle from basepoint" step. We used 180 degrees as an arbitrary example for our specific drawing, so you can follow the steps and use any angle. Hope this helps!
