specify which vertex color channels and/or texture
channels (map channels) to preserve. By default,
all vertex color channels are off (not preserved),
andalltexturechannelsareon(preserved).
Cr e ate —Lets you add ver tices to a single selected
poly object. Af ter selecting the object and clicking
Create, click anywhere in space to add free-floating
(isolated) vertices to the object. The new vertices
are placed on the active construction plane unless
object snapping is on. For example, with face
snapping on, you can create vertices on object
faces.
Collapse—Collapsesgroupsofcontiguousselected
vertices by welding them into a single vertex at the
selection center.
Attach—Lets you attach another object in the scene
to the selected editable poly. You can attach any
type of object, including editable meshes, splines,
patch objects, and NURBS objects. Attaching a
non-polymesh object converts it to editable-poly
format. Click the object you want to attach to the
currently selected poly object.
For f ur ther details, see
Attach .
Detach—Detaches the selected vertices and al l
attached polygons f rom the poly object, creating a
separate object or element. The Detach As Clone
option copies the polygons rather than moving
them.
You’re prompted to enter a name for the new
object. Detached polygons leave a hole in the
original object when you move them to a new
position.

Slice Pla ne—Creates a gizmo for a slice plane
that you c an position and rotate to specify where
to slice. Also enables the Slice and Reset Plane
buttons.
If snapping is tur ned off, you see a preview of the
slice as you transform the slice plane. To perform
the slice, click the Slice button.
Split—When on, the Slice and Cut operations
create double sets of ver tices at the points where
the edges are div ided. This lets you easily delete
the new polygons to create holes, or animate the

Quick Slice—Lets you quickly slice the object
without having to manipulate a gizmo. Make a
selection, click QuickSlice, and then click once
at the slice start point and again at its endpoint.
You can continue slicing the selection while the
command is ac t ive.
