Next, you’ll extrude
faces to create fingers for the hand.
To extrude the polygon faces to create
a perspective view, right-click LeftHand and select Face from
the marking menu.
This lets you select
- Select the right-most face by dragging
a selection box around the tiny box at its center. (The subsequent
illustration shows which face to select.)
Edit Mesh > Extrude.
the blue arrow manipulator outward a little to create the first
segment of the smallest finger.
The blue arrow turns
yellow when selected.
NoteDo not be alarmed
if the small dots at the center of each face do not appear. This
means you are in Select Faces by Whole Face mode,
which makes no difference for this tutorial. If you want to switch
to Select Faces by Center mode,
you can do this by opening the Maya preferences (Window
> Settings/Preferences > Preferences) and then
selecting the Selection section. You can
toggle the face selection mode from here.
- Repeat the prior two steps to create
the middle segment of the smallest finger.
- Repeat the prior two steps once again
to create the top segment and complete the finger.
By creating three segments
for a finger, you mimic a real finger’s natural structure. The borders
between the segments have vertices (not displayed currently) that
let you reshape those regions, for instance, to create knuckles.
- Similarly, extrude the ring, middle,
and index fingers from the appropriate wide faces. Don’t extrude
the three small faces that lie between the wide spaces. Leave them
in position to allow for webbing between the fingers.
NoteDo not be concerned
if the hand you create does not match the lesson’s illustrations.
Your goal in this lesson is to learn the workflow of subdivision
surfaces, not to perfect your modeling technique.
Next, you extrude a thumb
using similar techniques as you used for the fingers. The following
steps are abbreviated. See the preceding pages for details on the
described tools, if necessary.
To split and extrude a face for the thumb
- Select LeftHand.
Make sure it is highlighted
in green in the scene view. If it is not green, select LeftHand
in the Outliner.
Edit Mesh > Split Polygon Tool to
split the side face in the thumb region into three faces.
While splitting, make
sure the middle face is larger than the outer faces as shown below.
- Extrude the middle face and drag it directly
- Click the surrounding blue circle and
use the rotate manipulator to aim it in a direction appropriate
for a thumb.
three times more to create each segment of the thumb. Use the extrusion
manipulator to rotate, move, and scale each extrusion to create the
desired shape of a thumb. Use the following figure as a guideline. Again,
it’s unnecessary to match the illustration or create a realistic
thumb for this lesson.
The extrusion manipulator
is easy to figure out by clicking and dragging its various elements.
If necessary, you can also use the conventional Move, Scale, and
Rotate Tools to reshape the faces that control the thumb’s shape.
- In the scene view, right-click
LeftHand and select Vertex from the marking menu. The purple vertices
at the corners of the faces control the adjacent region of the hand.
coarse adjustments to various parts of the hand by repositioning
the vertices with the Move, Scale, and Rotate Tools.
Tool works on individual vertices or groups of vertices.
Rotate and Scale works on two or more vertices. Undo any changes

Try to create the approximate
thickness, length, and curvature of a cartoon character’s hand and
fingers. There’s no need for perfection. You’ll refine the fingers
