I’ve inserted a Polygon Object in my non-sequential system to use it as a rotating polygon mirror. I would like to rotate this object about its center axis (which currently points along the Y direction) .  Changing its Tilt About Y parameter rotates the polygon about its first face changing the X-Y position of the polygon too .  Is there a way to rotate instead about the center of the polygon so that it spins on its axis  ?

Hi Lenore,

You can introduce a dummy object and set its coordinate as the center axis. Then set the polygon object to rotate around this object.


Hi Yuan!  Thanks for the reply.  How do I set it up so that the polygon rotates about the dummy object ?  Thanks again!


Hi Lenore,

There is a setting called Ref Object. You can use it to put the polygon. The second null object can add more flexibility to rotate. You can find the sample file attached.
