Inter face
Amount—Sets the depth of the ext rusion.
Segments—Specif ies the number of segments that
wi ll be created in the extr uded object.
Capping group
Cap St art—Generates a flat surface over the start
of the extr uded object.
Cap End—Generates a flat surface over the end of
the extruded object.
Morph—Arranges cap faces in a predictable,
repeatable pattern, which is necessary for creating
Morph targets (page 1–309) .Morphcapping
can generate long, thin faces that don’t render
or deform as well as grid capping. Use m orph
capping primarily if you’re extruding multiple
morph targets.
Gri d—Arranges cap faces in a square grid trimmed
at the shape boundaries. This method produces a
surface of evenly sized faces that can be deformed
easily by other modifiers. When you choose the
Grid capping option, the grid lines are hidden
edges rather than visible edges. This primarily
affects any objects assigned a material with the
W ire option turned on, or any objects that use the
Lattice modifier (page 1–701) .
Output group
Pat ch—Produces an object that you can collapse to
apatchobject;see
Editing t he Stack (page 1–489) .
Mesh—Produces an object that you can collapse to
a mesh object; see
Editing the Stack (page 1–489) .
NUR B S —Produces an object that you can collapse
to a NURBS surface; see
Editing the Stack (page
1–489)
.
Genera te Ma pping Coords—A pplies mapping
coordinates to the extruded object. Default=off.
When on, Generate Mapping Coordinates applies
separate mapping coordinates to the end caps,

method used for texture mapped materials that
