(From Python...)

from pymol.cgo import *
from pymol import cmd

obj = []

obj.extend( [ CUSTOM_CYLINDER,
   1.0, 2.0, 3.0,  # XYZ 1
   4.0, 5.0, 6.0,  # XYZ 2
   2.0,            # Radius
   1.0, 1.0, 1.0,  # RGB Color 1
   1.0, 1.0, 1.0,  # RGB Color 2
   1, 1,           # End caps (0=none, 1=flat, 2=round)
   ] )

cmd.load_cgo(obj,'my_cgo')

Cheers,
Warren
