Chapter 8 Creating and Working with Solid Model Features
201
Surface
A surface object can be used as the slicing path. The surface can be planar or
nonplanar (curved). Surface modeling is discussed in detail in Chapter 10. Using a
surface as a slicing path is a technique that you can use to quickly create a mating die.
For example, refer to Figure 8-26. First, draw the required surface. The surface should
exactly match the stamped part that will be manufactured, Figure 8-26A. Then, draw
a box that encompasses the surface. Next, select the
SLICE
command, pick the box,
and press [Enter]. Then, enter the
Surface
option and select the surface. You may need
to turn on selection cycling or work in a wireframe display. Finally, when prompted
to select the side to keep, press
[Enter]
to keep both sides. The two halves of the die can
now be moved and rotated as needed, Figure 8-26B.
PROFESSIONAL TIP PROFESSIONAL TIP
You can use extruded surfaces, revolved surfaces, lofted surfaces, and swept surfaces
as slicing objects.

Z Axis
You can specify one point on the cutting plane and one point on the Z axis of the
plane. See Figure 8-27. This allows you to have a cutting plane that is not parallel to
the current UCS XY plane. First, select the
SLICE
command, pick the object to slice, and
press [Enter]. Next, enter the
Zaxis
option. Then, pick a point on the XY plane of the
cutting plane followed by a point on the Z axis of the cutting plane. Finally, pick the
side of the object to keep.
