Slice Modifier 817
Example: To slice ver tica lly through an object:
1.
Create a teapot (page 1–178) primitive.
2. Apply a Slice modifier.
TheSlicePlanegizmoappearsatthebaseofthe
teapot.
3. On the stack display, open the Slice modifier
and choose the Slice Plane g izmo.
4. MovetheSlicePlanegizmosoitintersectsthe
middle of the teapot.
5. Rotate the Slice Plane gizmo so it is vertical.
6. Tur n on Re move Top.
The back of the teapot is sliced away.
7. Turn on Remove Bottom.
The front half of the teapot is sliced away.

Modifier Stack
Slice Pla ne—At this sub-object level, you can
transform and animate the gizmo like any other
object to determine where the slice occurs. Scaling
the gizmo has no effect, because its extents are
effectively infinite. If you n eed to limit the extent
of the slice, use it on a sub-object selection set of
faces, rather than on the entire object.
For more information on the stack display, see
Modifier Stack (page 3–802) .
Slice Parameters rollout
Slice Type—Defineshowthesliceplanewillaffect
the geometry to which it has been applied.
•
Refine Mesh—Adds new vertices and edges
along the intersection of the geometry with
the slicing plane. Faces cut by the plane are
subdivided int o new faces.
•
Split M esh—Adds a double set of vertices and
edges along the plane boundary producing two
separate meshes (one on either side of the slice
plane), which you can modify differently if
desired. U se this to break a mesh in two.
•
Remove Top—Deletes all the faces and vertices
abovetheSlicePlane.
•
Remove B ottom—Deletes a ll the faces and
vertices below the Slice Plane.
Opera te O n—Choose one of these buttons to
specif y how the slice handles quads and other
polygons.
•
Faces—Treats the selec tion set as a set
of triangular faces, slicing each one in turn.
Outputs a
mesh-type object (page 1–984) .
•
Polygons —Converts the object to
a polygon mesh based on visible edges,
