Before you plot, you can establish the scale factor for the view in each viewport. Scaling views relative to paper space establishes a consistent scale for each displayed view. For example, the following illustration shows a Paper space view with several viewports—each set to different scales and views.
在打印之前，可以为视图在每个视口中创建精确的缩放比例因子。相对于图纸空间来缩放视图将为每个显示的视图建立一致的缩放比例。例如，以下图解显示了具有多个视口的图纸空间—每个视口均被设置为不同的比例和视图。
When you work in Paper space, the scale factor represents a ratio between the size of the plotted drawing and the actual size of the model displayed in the viewports. To derive this scale, divide paper space units by Model space units. For a quarter-scale drawing, for example, you specify a scale factor of one Paper space unit to four Model space units (1:4).
如果使用图纸空间，比例因子代表打印图形的大小与视口中显示模型的实际尺寸之间的比例。要获得此比例，请将图纸空间单位除以模型空间单位。例如，对于四分之一比例图形，可以将比例因子指定为一个图纸空间单位对应四个模型空间单位 (1:4)。
The StandardScale and CustomScale properties are used to specify the scale for a viewport. The StandardScale property accepts a value based on the StandardScaleType enum; whereas the CustomScale property accepts a real number which represents the ratio of units between Model and Paper space. For example, the real value equal to 1:4 is 0.25.
StandardScale 和 CustomScale 属性常常用于为视口指定比例。StandardScale 属性接受一个 StandardScaleType 枚举值；但是 CustomScale 属性接受一个真实的代表 模型和图纸空间之间单位的比率的数值。例如，等于1：4的真实的值是0.25。
The following illustrations show the view of the model at a scale of 1:1, and then the same model view show at scales of 2:1 and 1:2. A scale of 2:1 increases the view of the model to twice the size of the paper space units; while a scale of 1:2 displays the model at half its actual size.
下面的图解显示了模型在1：1的比例下的视图，以及同样的模型显示在比例为2：1和1：2下的视图。2：1的比例增加模型的视图为图纸空间单位尺寸的两倍；而1：2的比例将以它的实际大小的一半来显示模型。
