E, Shift-E

当您按下 E 时，对于每个选定的末端(显式或隐式)，将创建一个新骨骼。这个骨头将成为“它的”末端所有者的子级，并与之相连。像往常一样，一旦完成挤压，只选择了新骨骼的末端，并且在选择模式下，您可以根据自己的喜好放置它们。见图挤出实例。。

挤出实例。
选择了三个尾端的骨架。	三个挤出的骨骼。

你也可以使用旋转/缩放挤出，如网格那样，分别的按 E R 和 E S —— 以及沿一个全局或局部轴锁定( locked )的挤压。

镜像挤出示例。

Bones have an extra “mirror extruding” tool, called by pressing Shift-E. By default, it behaves exactly like the standard extrusion. But once you have enabled X 轴镜像 editing option, each extruded tip will produce two new bones, having the same name except for the “_L”/ “_R” suffix (for left/right, see the naming conventions). The “_L” bone behaves like the single one produced by the default extrusion — you can move, rotate or scale it exactly the same way. The “_R” bone is its mirror counterpart (along the armature’s local X axis), see Fig. 镜像挤出示例。.

Important

取消挤压命令将使新创建的骨骼重新回到源位置，(创建零长度的骨头，就是骨骼还在)。当退出编辑模式时这些骨骼才将被移除，然而这会引起混乱和不会像你想要的那样保持它们。如果你认识到这个问题立刻使用undo命令撤消挤压动作。

In case you are wondering, you cannot just press X to solve this as you would in mesh editing, because extrusion selects the newly created tips, and as explained below the Delete tool ignores bones’ joints. To get rid of these extruded bones without undoing, you would have to move the tips, then select the bones and delete them.
