A PlotSettings object is similar to a Layout object, as both contain identical plot information and this is because the Layout class is derived from the PlotSettings class. The main difference is that a Layout object has an associated BlockTableRecord object containing the geometry to plot. A PlotSettings object is not associated with a particular BlockTableRecord object. It is simply a named collection of plot settings available for use with any geometry. PlotSettings objects are known as page setups in the AutoCAD user interface and are accessed from the Page Setup Manager.
