## 设置 A/D 2D：#

Example 1: Set the Input variables to two vertices in Edit Mode in Front view, set `Working Plane` to Front, select the rotational vertex, select the center vertex. The Distance variable is set to the apparent separation fo the two vertices in the front view, the Angle is set to the apparent angle relative to horizontal in the front view, the X, Y & Z inputs are set to the delta offset between the two vertices in the `view` axes.

Example 2: Set the Input variables to two objects in Object Mode in Top view, set `Working Plane` to Top(X-Y), select the rotational object, select the center object. The Distance variable is set to the apparent separation of the two objects in the top view, the Angle is set to the apparent angle relative to horizontal in the top view, the X, Y & Z inputs are set to the delta offset between the two vertices in the `view` axes.

## 设置A/D 3D：#

Example 1: Set the Input variables to three vertices in Edit Mode, select the two rotational vertices, select the center vertex. The Distance variable is set to the real separation of the first vertex and center vertex in the front view, the Angle is set to the real angle between the three vertices, X, Y & Z inputs are set to the delta offset between the first and center vertices.

## 锥度：#

Selection: Select vertices to be moved, then select fulcrum vertex with SHIFT+Mouse, active vertex is considered the rotational center.

Example 1: Taper the end of a cube in front view - 25 degrees, set Angle to -25 degrees (25 degrees clockwise), select all vertices to be tapered, SHIFT+Mouse select center of rotation point vertex, set Move/Rot selector to `RotY,MovX`, set Working Plane to Front(X-Z), click `Taper`.

`旋转Y,移动X` 的意义在于，Y轴被用作旋转轴，顶点将沿着X轴移动，在视图 `工作平面` 模式下，记住这些是 `本地` 轴，而不是 `全局` 轴。
