Typically, when you plot a large drawing such as a floorplan, you specify a scale to convert the real drawing units into plotted inches or millimeters. However, when you plot from Model space, the defaults that are used if there are no settings specified include plot to system printer, plot the current display, scaled to fit, 0 rotation, and 0,0 offset.
通常情况下，当打印较大的图形时，例如平面布置图，可以指定一个比例将实际图形单位转换为打印英寸或毫米。如果从模型空间打印时未指定设置，则使用默认设置。默认设置包括打印到系统打印机、打印当前显示、缩放到充满、0 旋转和 0,0 偏移。
You use a PlotSettings object to modify the plot settings of the layout to plot, and then validate the plot settings with a PlotSettingsValidatorobject before passing the PlotSettings object to a PlotInfo object. Once the Plot Info object is defined, you use a PlotEngine object to output create the plot and pass to it the PlotInfo object that contains the information of the sheet or layout to plot.
要修改用于打印的布局的打印设置可以使用 PlotSettings 对象，然后在传递 PlotSettings 对象给 PlotInfo 对象之前使用 PlotSettingsValidatorobject 验证打印设置。只要打印信息被定义，用户就可以使用 PlotEngine 对象输出创建的图和传递给它的 PlotInfo 对象，它包含图形和打印布局的信息。
This example establishes several plot settings before generating the final plot. The output generated is a DWF file named Myplot. Before running this example, you might want to add some objects to Model space first.
本样例在生成最终的打印图之前确定了几个打印设置。输出生成的 DWF 文件被命名为 Myplot。在运行本例前，用户首先需要添加几个对象到模型空间中去。
