Pres er ve UVs S etti ngs—Opens the
Preserve Map
Channels dialog (page 1–1076)
,whichletsyou
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 —Creates an edge from vertex to vertex.
Click Create, click a vertex, and then move the
mouse. A rubber-band line extends from the
vertex to the mouse cursor. Click a second,
non-adjacent vertex on the same polygon to
connect them with an edge. Repeat, or, to exit,
right-click in the viewport or click Create again.
Edges you create separate the polygons. For
example, by creating an edge inside a quadrilateral
polygon, yo u turn it into two triangles.
Collapse—Collapses selected borders by welding
their vertices to a vertex at the selection center.
In effect, this “covers,” or removes, the hole defined
by the border.
Attach—Lets you attach another object in the scene
to the selected editable poly. You can attach any
type of object, including splines, patch objects,
and NURBS surfaces. Attaching a non-mesh
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 borders and all
attached polygons f rom the poly object, creating a
separate object or element. The Detach As Clone
option copies the polygons rather than detaching
them.

.
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.
As you transform the slice plane, you see a preview
of where the slice w ill occur in the mesh object. 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
newpolygonsasseparateelements.
Slice—Performs the slice operation at the location
of the slice plane. Available only when Slice Plane

.
Reset Plane—ReturnstheSliceplanetoitsdefault
position and orientation. Available only when
Slice Plane is on.
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.
To stop slicing, right-click in the viewport, or click
QuickSlice again to turn it off.
Note: At the Border sub-object level, QuickSlice
affects the entire object. To slice only specific
polygons, u se QuickSlice on a p olygon selection at
the Poly sub-object level.
