Building a Teakettle
Now that you have experienced the mechanics of subdivision surface modeling and edit-
ing, you’re ready to work on another model. The next subdivision exercise asks you to cre-
ate a teakettle. You’ll fashion the kettle from simple polygon shapes and then refine it
using subdivisions.
Creating the Base Polygon Model
To create the base poly mesh for the kettle, follow these steps:
1. The main body of the kettle will begin as a poly cylinder. Choose Create
Polygon
Primitives
Cylinder
to open the Options box. Set Subdivisions Around Axis to
8, and set Subdivisions Along Height to 4.
2. To create the lid, create another poly cylinder with eight subdivisions around the axis
and 2 for the height. Scale it to fit as a lid on the first cylinder.
3. Select the upper row of poly edges on the lid and scale them all in to create a bevel, as
shown in Figure 6.34. Then select every other edge on the top surface and delete
them, as shown in Figure 6.35.
Figure 6.35
Delete every other edge of the top surface.

Scale the outer edges inward.
You can use these same techniques to re-create the polygon hand from Chapter 4 with sub-
division surfaces.

4. Select the poly edges of the main cylinder, and scale them out increasingly larger as
you work your way down. Delete every other edge of the top surface as you did with
the lid. Your kettle should look like the one in Figure 6.36.
5. You are going to create a simple handle for the lid. Select the lid’s top four faces. You
will create the handle by extruding these faces and scaling them in. First, make sure
the option Edit Mesh
Keep Faces Together is enabled. This option lets you extrude
these faces properly by keeping the poly faces together during the extrude operation.
Now select the four faces again and choose Edit Mesh
Extrude
. Choose Edit
Reset Settings to make sure the settings are correct, and click Extrude. Use the scale
handles to scale the extruded faces in, as shown in Figure 6.37.
6. With those four faces still selected, extrude the faces again, but this time pull them up
and scale them in a bit as shown in Figure 6.39.
7. Select the side faces of the lid’s new handle, and extrude the faces inward using the
scale handle to create detail on the handle.
Figure 6.37
By default, faces will extrude separately.
Figure 6.36
Creating the overall shape
If instead of following these directions you choose Edit Mesh
Extrude and use the special
scale handles shown in Figure 6.38, your faces may all separate.

8. Select the edges that make up the lid handle, and move them to round out the handle,
as shown in Figure 6.40.
9. Select the four faces on the top of the kettle and extrude them. Scale the faces in and
pull them up to round the top of the kettle, as shown in Figure 6.41.
