  1. From the Wall dialog box, select a Rotating Wall.
  2. Specify the Angular velocity, which describes how quickly the wall rotates.

    You can also click to specify a scale factor and amplitude for each component of the angular velocity vector.

  3. Specify the Axis of rotation to describe whether the wall rotates about the x-, y-, or z-axis in the axis system that you specify.
  4. Specify the orientation of the wall's rotation using the Axis system definition options:
    OptionDescription
    Global Align the rotation with the global coordinate system.
    LocalAlign the rotation with a local coordinate system, then select the local coordinate system from the 3D area.
    SpecifyAlign the rotation directly by right-clicking the feature triad glyph on the model and selecting an orientation tool.
