I'm not sure exactly what you need, but you can create graphics objects 
easily enough by script:

create invisible graphic "NewLine"
set the style of graphic "NewLine" to "line"
set the points of graphic "NewLine" to "100,100" & cr & "200,200"
-- then set colors, thickness etc.
show graphic "NewLine"

If you want to make lost of similar objects, set the properties for the 
templateGraphic first, then each object will start off with those 
properties.
