face constraints. Also, it’s better to perform one big
move than several smaller moves, as multiple small
moves can begin to distort the mapping. However,
if you need to perform extensive geometry editing
while preserv ing mapping, use the
Channel Info
utility (page 2–1549)
instead.
Pres er ve UVs S etti ngs—Opens the Preserve Map
Channels dialog (page 1–1076)
,whichletsyou
specify the 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, creati ng an edge inside a quadrilateral
polygon turns it into two t r iang les.
Collapse—Collapses selected edges by welding
their vertices to a vertex at the selection center.
Attach—Lets you attach another object in the scene
to the selected Edit P oly object. Click the object
you want to attach to the cur rently selected Edit
Poly object.
You can attach any ty p e of geometry object,
including splines and patch objects. Attaching a
non-mesh object converts it to Edit Poly format.
For f ur ther details, see
Attach .
Attach Li st—Lets you attach other objects in
thescenetotheselectedEditPolyobject.Click
to display the Attach List dialog, where you c an
choose, by name, multiple objects to attach.
Detach—Detachestheselectededgesandall
attached polygons from the E dit Poly object,
creating a separate object or element. The default
settings are those most recently set in the Det ach
dialog, available from the Detach Settings button
(see following).
Detached edges leave a hole in the original object
when you move them to a new position, unless you
use the Deta ch As Clone option.

Note: Any Detach settings you change are
automatically saved as program defaults.

mesh along a plane (Slice) or in a specific area
(Cut).
Note: In Animate mode, you begin a slice operation
by clicking Slice, not Slice Plane. You still need to
click Slice Plane to move the plane around. You
can animate the slice plane.
Slice Pla ne—Creates a gizmo for a slice plane that
you can position and rotate to specify w here to
slice. In Model mode, clicking Slice Plane enables
the Slice and Reset Plane buttons. In Animate
mode, Slice Plane is available only after clicking
Slice, and you can animate the slice plane.
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.
