pixel visualizer help

[Avind]

Another help item please.....   I would like to create a fixture / prop for RGB lights using DMX.  The item I am trying to create is a wreath with two sections.  The inner section has 54 lights in three rows of 18.  The outer wreath has 99 lights in 3 rows of 33.  I can use the "Insert Fixture from Symbol" function which will allow me to add 16 lights with no specification regarding where the first pixel is.  Because I am dealing with circles, the DMX line tool does not work.  I have no desire to do this by generating 153 individual bulbs.  Does anyone know of a method to create a fixture that will allow me to complete this without hours of painful dot making?
