RIGGING

Edit bone tool

The Edit bone tool fixes a rig's bones without touching the animation: it moves joints and changes a bone's length and rest angle, and the artwork attached to the bones stays where it is. Here the arm's bones were drawn a little off, so the arm bends in the wrong places as it waves.

The arm waves, turning at the shoulder and the elbow: the same keyframes as before, on bones that now sit at the joints.
WHAT YOU’LL MAKE

The arm waves, turning at the shoulder and the elbow: the same keyframes as before, on bones that now sit at the joints. This one is the real exported SVG, playing.

Step by step

  1. Pick the Edit bone tool

    Press E. The Edit bone tool is in the bones button of the tools on the left. The bones show their rest pose, and a Rest pose chip above the canvas says the keyframes stay as they are.

  2. Move the joint onto the shoulder

    Drag the round joint at the start of Bone 1 up onto the shoulder. The joint moves, the bone's tip stays where it is, and the upper arm doesn't move.

  3. Drag Bone 1's tip to the elbow

    Drag the round tip of Bone 1 onto the elbow. Bone 1 gets longer and turns, and the joint of Bone 2, which sits on that tip, comes along while its own tip stays put.

  4. Bring Bone 2's tip to the wrist

    Drag the tip of Bone 2 back to the wrist. Bone 2 gets shorter; the forearm stays as it is.

  5. Play it

    Press V for the Select tool, then Space. The wave's keyframes haven't changed, but now the arm turns at the shoulder and the elbow.

Good to know. Drag a bone between its ends to move the whole bone; what is attached stays put. While dragging a tip, hold Shift to snap its angle to 15°, or Ctrl to turn the attached artwork with the bone; a tip also snaps onto other bones' joints and tips. A joint that sits on its parent's tip moves that tip: Alt+drag pulls the joint off it.
