Hi Andy, not to take anything away from Max, but FYI the pattern you show there can be done with the built in Transform > Array > Circular command pretty easily. You'd just do it in 3 passes increasing the "Item count" option on each pass.

It looks like this:

Pass 1 - Item count = 9:



Pass 2 - Item count = 14:



Pass 3 - Item count = 19
