Hi, I am trying to set a pen setting for a drawing just before it gets plotted. I have tried the Developer Documentation, whose instructions are: ACADPref.DefaultPlotStyleTable = <path to ctb file> but this doesn't apply the style to the drawing at all (the drawing is plotted as if no styles had been applied. Is this clear enough, or should I provide more explanation? If anyone has any ideas, I would appreciate some help very much. Thanks, Alex
