The Rotate Orientation option rotates the 0 degree reference orientation by 90 degrees (about the blue arrow of triad) for a face of shell. The option is similar to the Rotate 0º Reference but applies to individual faces of a shell.
For a description of arrows and what they represent, see Ply Angle.

For the shell face above, the stripes rotate about the axis normal to the plane (blue arrow) by 90 degrees in counter-clockwise direction. As a result, the 60 degrees ply angle (yellow arrow), when Rotate Orientation is selected, corresponds to -30 degrees ply angle before rotation.
