If you want AutoCAD to use defaults that differ from those used by Windows, you can create a PC3 for a system printer. If you have a PCP or PC2 file that contains setup information about the plotter, you can import it into the PC3 file. The model tab is where you draw your geometry. A layout shows a preview of a plotted page. Each layout represents a separate paper space environment.
Every drawing can contain multiple layouts associated with different plotters and page setups.
Like paper space in previous versions of AutoCAD, title blocks, notes, and other plot-only objects are drawn in the layout. To view model space objects, create floating viewports. When you create a layout, you specify a plotter, page size, and plot orien-tation. You control these settings for layouts and the model tab using the Page Setup dialog box. Page Setup dialog box.
