Start by creating the first pose of your animation. This tutorial shows a swimming animation, but yours can be whatever you envision. Depending on the animation you want to create, your first pose may be very different.
Posing figures is done by rotating individual parts and joints, like the head or elbow.
To rotate, click on a body part. A set of handles will appear.
Rotate by dragging the handles. Each handle rotates in a different direction. Undo any change with (Ctrl + Z or ⌘ + Z).
Continue to rotate different parts until the first pose is complete. While working, change the camera to see the pose from multiple angles.
