What you're trying to do will be very hard to do with pcb commands.
The commands are only good for doing certain preordained actions.  Not
for general things like placing components.

Another trap:  You might want to connect your circles of LEDs with
arcs.  Be advised that pcb affers no facilities for editing arcs.

You would be wise to avoid PCB for anything non-rectangular.  It is
exceedingly painful.
