Radial Copy Question

[JKEdmo]

Good afternoon,

 

I'm building a curved pergola and want to distribute some purlins radially across the top of the shaped / curved beam below:

 

 

Is a radial copy even possible with Chief?  If so, could someone point me towards a video or forum thread that explains the process please?  I had trouble finding this.

 

Thanks again,

 

Jim
