Array tool help

In SILO I can make a circle that allows for "spokes" where I can choose any number of spokes. It creates a flat circle. From there I can use the array tool and place another object on the ends of the spokes. I was trying to do this with NVIL but am not understanding how to do the same operation. Can this be done simply like SILO or is it a different approach?
Thanks,

Darkvizer,
  Thanks. I had already found the array and instance info with a search here but was having trouble getting it to work as it is different from SILO. I went back and played around some more and got it working. Lots to learn.
