In the following steps, you will create an outline of the head by creating one
strip of polygons and then forming them to the side image plane. You will
extrude 15 times and move the edges to create the general form of a head. Be sure to keep the outer edge of the head inside the edges of the image plane; that way, you’ll have room to fit the head accessories.
1. You should still have the edge selected from the previous exercise.
Use extrude-move again, but when you finish one polygon, release
the mouse button; then click again and move the edge to create
another extruded polygon. You’ll do this 14 more times, following
the form of the head in the image plane, as shown in Figure 9.4.
FIguRe 9.4 Following the image plane, create the head outline using the
2. In the Front viewport, select the edge on the top base of the neck
about where the ear might be. Using Shift+Move, position a polygon strip as you did in step 1, but this time for the side of the head.
Extrude a total of five segments up from the neck. In Edge mode, use
Bridge (on the Poly: Edit aEdges achoose Bridge) to fill the gap
between the side of the head and the nearest edge on the top of the
head, as shown in Figure 9.5.

3. To build the front of the face, start by selecting the two edges just
under the chin and use Shift+Move to extrude them out to the right,
as shown in Figure 9.6. In Vertex mode, select the Graphite Modeling
Tools ribbon and choose Vertices aTarget Weld. To use Target Weld,
click on one vertex and drag a line to the other to fuse the vertices
together. So first click the vertex on the new polygon closest to the
neck, and then click on the neck vertex, shown in Figure 9.6. This
will fuse the new polygons for the jowls to the neck.
4. Back in Edge mode, select the two rightmost edges of the polygons
you just created for the jowls, and then use Shift+Move to extrude
those edges up on the Z-axis. Match the number of segments with
the segments on the outer head strip you already created. The result
is shown in Figure 9.7.
5. Select the edges shown on the left side of Figure 9.8. Use Bridge to
curve the strip toward the forehead, as shown in Figure 9.8.
FIguRe 9.8 Use Bridge to close the gap.
6. As you did in step 5, in Edge mode use Shift+Move to extrude another
row of polygons in toward the front of the face. Then in Vertex mode,
use Target Weld on either side of the front face strip, as shown in
FIguRe 9.9 Use Shift+Move and then use Target Weld.
7. Looking at the ring of edges from the front of the strip of the head
to the side of the head, it’s clear you don’t have enough horizontal
edges. Select the edge closest to where the bridge of the nose would
be, and then use Chamfer (from the Graphite Modeling Tools ribbon,
choose Edges aChamfer Settings aChamfer Settings) with an
Edge Chamfer Amount value of 1.346, and then click OK. Try to
keep the edges equally spaced, as shown in Figure 9.10.
FIguRe 9.10 Chamfer the edge that falls at the bridge
of the nose.
8. Select the eight edges on the front of the face and the side of the face,
and then use Bridge, as shown in Figure 9.11. Notice that there is
nowhere to weld to on the vertical edge on the top of the head. You
need to create another edge running down the front of the face and
then weld the vertices together to close the head.
9. From the Graphite Modeling Tools ribbon, choose Edit to access the
Cut tool. Then cut from the dead-end edge at the top of the head down
to the bottom of the neck, as shown in Figure 9.12. Make sure you start
and end the cut directly on the vertices.
10. In Vertex mode, select the two vertices at the top of the cut; from the
Graphite Modeling Tools ribbon, choose Vertices aWeld and modify
the Weld Threshold setting until the two vertices are welded together.
