变换方向 影响 变换: 位置, 位置, 与 缩放 操作。 可以看到 物体控制器 (位于选中项的中心), 和变换约束, 轴向锁定 的效果。

For example, when you press X, during the execution of the operation, it will constrain the transformation to the Global X axis. But if you press X a second time it will constrain to your Transform Orientation's X axis.

变换方向选择器。

The Orientations options can be set through the Transform Orientation selector in a 3D View header, with Alt-Spacebar, or in the Transform Orientations panel in the Properties region.

In addition to the five preset options, you can define your own custom orientation (see Custom Orientations below).

方向

全局

The manipulator matches the Global (or World) axis.

The Mini Axis in the lower left corner of the viewport, and the Grid Floor, shows the axes of world coordinate system.

自身

The manipulator matches the Object axis.

When an object is rotated, the direction of the Local manipulator matches to the object's rotation relative to the global axes. While the Global manipulator always correspond to world coordinates.

法线

The Z axis of the manipulator will match the Normal of the selected element. If multiple elements are selected, it will orient towards the average of those normals.

In Object Mode, this is equivalent to Local orientation.

万向

视图

The manipulator will match the 3D View (viewport):

  • Y: 向上/向下
  • X: 左/右
  • Z: Towards/Away from the screen

示例

Cube with the rotation manipulator active in multiple transform orientations.

自定义的方向

参考

模式:物体与编辑模式
面板:属性栏 ‣ 变换方向
快捷键:Ctrl-Alt-Spacebar

You can define custom transform orientations, using object or mesh elements. Custom transform orientations defined from objects use the Local orientation of the object whereas those defined from selected mesh elements (vertices, edges, faces) use the Normal orientation of the selection.

../../../../../../_images/editors_3dview_object_editing_transform_control_orientations_custom.png

Transform Orientations panel.

The Transform Orientations panel, found in the Properties region, can be used to manage transform orientations: selecting the active orientation, adding ("+" icon), deleting ("X" icon) and rename custom orientations.

这些方向的默认名称来自你选择的任何东西。如果是一个边,它将被称为“边”,如果是一个物体,它将采取该物体的名字,等等。

创建参照坐标系(方向)

To create a custom orientation, select the object or mesh element(s) and press Ctrl-Alt-Spacebar, or click the "+" button on the Transform Orientations panel in the Properties region.

../../../../../../_images/editors_3dview_object_editing_transform_control_orientations_custom-name.png

Create Orientation operator panel.

Just after creating the orientation, the Create Orientation Operator panel gives a few options:

名称
用于命名新方向的文本字段。
使用视角
新的方向将与视图空间对齐。
创建后使用
如果选中,则会使新创建的方向处于活动状态。
覆盖之前
如果新的方向被赋予一个现有的名字,一个后缀将被添加到它,以避免覆盖旧的,除非 覆盖之前 被选中,在这种情况下,它将被覆盖。

与变换方向对齐

菜单:物体 ‣ 变换 ‣ 对齐到变换参照坐标系

对齐(旋转)所选物体,使其自身方向与变换参照坐标系面板中的激活变换方向或变换操作面板中的 方向 选择相匹配。
