Selecting

You can select and edit bones of armatures in Edit Mode and in Pose Mode. Here, we will see how to select bones in Edit Mode. Selecting bones in Pose Mode is similar to selecting in Edit Mode with a few specific differences that will be detailed in the posing part.

Similar to vertex/edge selection in meshes, there are two ways to select whole bones in Edit Mode:

  1. Directly, by selecting the bone's body.

  2. Selecting both of its joints (root and tip).

This is an important point to understand, because selecting bones' joints only might lead to non-obvious behavior, with respect to which bone you actually select.

Note that unlike the mesh display type, the armature display type has no effect on selection behavior. In other words, you can select a bone's joint or body the same way regardless of the bone visualization chosen.

Selecting Bone Joints

To select bones' joints you have the standard selection methods.

Inverse Selection

As stated above, you have to remember that these selection tools are for bones' joints only, not the bones' bodies.

For example, the Inverse selection option Ctrl-I inverts the selection of bones' joints, not of bones (see Inverse selection).

Remember that a bone is selected only if both its joints are selected. So, when the selection status of bones' joints is inverted, a new set of bones is selected.

The result of the inverse selection Ctrl-I: The bones joints selection has been inverted, and not the bones selection.

Selecting Connected Bone Joints

Another example is: when you select the root of a bone connected to its parent, you also implicitly select the tip of its parent (and vice versa).

Note

Remember that when selecting bones' joints, the tip of the parent bone is the "same thing" as the root of its children bones.

Selecting Bones

By clicking on a bone's body, you will select it (and hence you will implicitly select its root and tip).

Using Shift-click, you can add to/remove from the selection.

You also have some advanced selection options, based on their relations.

Pick Shortest Path Ctrl-click

Selects the path from the active bone to the bone under the mouse.

Deselecting Connected Bones

There is a subtlety regarding connected bones.

When you have several connected bones selected, if you deselect one bone, its tip will be deselected, but not its root, if it is also the tip of another selected bone.

To understand this, look at Fig. Bone deselection in a selected chain..

A selected chain.

Two selected bones.

After Shift-clicking "Bone.003":

  • "Bone.003" 's tip (which is same as "Bone.004" 's root) is deselected.

  • "Bone" is "Bone.003" 's parent. Therefore, "Bone.003" 's root is the same as the tip of "Bone". Since "Bone" is still selected, its tip is selected. Thus the root of "Bone.003" remains selected.

Select ‣ Select Pattern...

Selects all bones whose name matches a given pattern. Supported wild-cards: * matches everything, ? matches any single character, [abc] matches characters in "abc", and [!abc] match any character not in "abc". As an example *house* matches any name that contains "house", while floor* matches any name starting with "floor".
