In Pose Mode, select the Lower Arm Bone,

press R Key (rotate) and drag the Mouse. The

Lower Arm Bone rotates about its Base moving

Stroke Control Points

Obviously employing this method relies on

accurately

constructing

the

Stroke

and

positioning the Armature relative to the Stroke.

In Figure 13.12 there is an error in positioning.

The Error: As shown in Figure 13.12, rotating the Bone affects only part of the Stroke

representing the lower arm and hand. This occurs since part of the Stroke forming the hand has

not been linked with the Bone. Part of the hand is left in situ when rotation takes place.

13.6 Understanding Parenting

To understand what is happening behind the scenes

during the Parenting procedure look at the Outliner Editor.

In the first instance adding an Armature to the Scene sees

a new Canvas named Armature appear in the Outliner.

Obviously this is not a Canvas on which you draw Strokes

but a container housing the data for the Armature itself.

In the 2D Viewport Editor, shift selecting the Stroke then the Armature in Object Mode, pressing

Ctrl + P and selecting With Automatic Weights, parents the Stroke to the Armature.

Figure 13.14

In the Outliner Editor you will see that the Canvas named

Stroke is relocated under Armature in the hierarchy.

You will also observe that Modifier has been added under

Stroke which indicates that a Modifier has been added to

the Stroke. In this case

the

Modifier

is

an

Armature Modifier. You

can

see

this

by

selecting the Stroke in

Object Mode in the 2D

Viewport

Editor

and

going to the Properties

Editor, Modifier Properties Tab (Figure 13.15).
