### Building the Jaw

The jaw, despite being a relatively smooth structure, defines a major contour of the face and is important in terms of overall proportion. It’s a good idea to add it in at this stage as you start to see more of the face coming together.

Exercise 10.11 Adding the Jaw Line

1.
Hide the polygons you’ve created thus far before you start building the jaw. Hiding the polygons from the Display tab does not remove them. It only makes them invisible so that you don’t harm the work you’ve already done. You also can work in another layer and then copy and paste later if you like. Make sure Symmetry mode if off at the bottom of the Modeler screen, and do not have the SubPatch mode active (Tab key).

2.
Use the Points tool to lay down a row of five profile points, as in Figure 10.34. These should curve in toward the neck area at the bottom. Remember to pay attention to all viewports as you build.

##### Figure 10.34. Lay down a row of five profile points for creating the jaw line.

3.
Using the Extender tool to multiply the points, rotate (y), stretch (h), and move (t) the points to fill out the jaw line, as in Figure 10.35.

##### Figure 10.35. Extend the jaw line so that you have six rows of polygons, from the start of the jaw near the ear to the centerline on the x-axis.

You should have six rows of polygons, from the start of the jaw near the ear to the center x-axis.

Tip

Remember to cull those pesky back polygons from the Extender operations, and make sure the extended geometry is aligned to face the right direction.

4.
Use Set Value (Ctrl+v) to make sure the last row of points sits exactly on the x-axis. Then mirror them to create the other half of the jaw.

5.
Finally, use the Drag (Ctrl+t) and Stretch (h) tools to refine the jaw shape, and press the Tab key to activate SubPatch mode to see the smooth shaped jaw, as in Figure 10.36. Save your work.

##### Figure 10.36. Here is the completed jaw surface.
