Generally, you draw objects at their actual size. When you plot the drawing, you either specify a precise scale or fit the image to the output size. You specify a scale with either a standard or custom plot scale.
通常情况下，用户是以实际尺寸来绘制对象。当打印图形时，即可以指定精确比例，也可以根据图纸调整图像尺寸。要指定比例，即可以指定标准的打印比例也可以使用自定义的打印比例。
A standard scale is used when the UseStandardScale property is set to TRUE. The actual scale at which the plot will be scaled to can be queried with the StdScale property.
当使用标准比例时，UseStandardScale 属性要设置为 TRUE。然后可以使用 StdScale 属性获得实际的打印比例。
A custom scale is used when the UseStandardScale property is set to FALSE. The custom scale at which the plot will be scaled to can be queried with the CustomPrintScale property.
当使用自定义比例时，UseStandardScale 属性要设置为 False。然后可以使用 CustomPrintScale 属性获得实际的打印比例。
When reviewing an early draft view, a precise scale is not always important. You can set the StdScaleType property to a value of ScaleToFit defined by the StdScaleType enum to plot the layout at the largest possible size that fits the output size.
查看初期的草图视图时，通常并不需要精确的比例。可以设置 StdScaleType 属性为的 StdScaleType 枚举定义的 ScaleToFit 值，以适合图纸的最大可能尺寸来打印布局。
