缩小到上一个/0.5：恢复到上一个设置的缩放窗口，如果没有设置缩放窗口，就按当前几何的50％缩小。
放大所选的：仅放大预先选取的图元。自动放大所选的图元到图形窗口适度化。
缩小0.8倍：按当前显示几何的80％缩小图形。
1.3.6 设置Z深度
在状态栏上的“Z”区域使用下述方法之一设置几何或刀具路径的Z深度值：
1. 在区域内输入值。
2. 单击下拉箭头选择一个最近使用的值。
3. 单击“Z”标签，在几何窗口中选取一个位置，使用其Z值。
1.3.6.7二维和三维工作模式
在“二维”模式（如图1-156所示），所绘制的几何位于以当前设置的Z深度，且平行于绘图平面的平面上。
在“三维”模式，X、Y、Z坐标读取于动态绘图时的光标。状态栏上的的Z深度不可用。工作在三维模式，可以绘制点在不同平面上的图元。
1.3.6.自定义工作空间
使用“设置”“自定义”菜单，可以设置“工具栏”（如图1-57所示）和“下拉/右击菜单”（如图1-58所示）。
















1.3.6.设置缺省值
设置配置
“系统配置”对话框（如图1-59所示）包括多项不同的页。在左侧单击不同的名称，进入不同的设置。
