generallybedescribedastheedgeofahole.Thisis
usually a sequence of edges with polygons on only
one side. For example, a box doesn’t hav e a border ,
but the teapot object has several: on the lid, on the
body, on the spout, and two on the handle. If you
create a c y linder, and then delete an end polygon,
the adjacent row of edges forms a border.
At the editable poly B order sub-object level,
you can select single and multiple borders and
transform them using standard methods. This
topic covers the Edit Geometry and Edit B orders
rollouts; for other controls, see
Editable Poly (page
1–1012)
.
Procedure
To create a polygon that closes the sur f ace a t the
selected bor der:
1.
At the Border sub-object level, select any open
edge.
This selects the entire closed loop of continuous
open edges that make up the border selection.
2. Click Cap.

See
Editable Poly (page 1–1014) for information
on the Selection rollout settings.
Soft Se lection rollout
Soft Selection controls apply a smooth falloff
between selected sub-objects and unselected
ones.WhenUseSoftSelectionison,unselected
sub-objectsnearyourselectionaregivenpartial
selection values. These values are shown in the
viewports by means of a color gradient on the
vertices, and optionally on the faces. They affect
most ty pes of sub-object deformations, such as the
Move, Rotate, and Sca le funct ions, as well as any
deformation modifiers (such as Bend) applied to
the object. This provides a magnet-like effect with
a sphere of influence around the selection.

Edit Borders rollout
This rollout includes commands specific to editing
borders.
Note: To delete a border, select it and press the
DELETE key. This deletes the border and all
attached polygons.
Ex trude—Lets you extrude a border manually via
direct manipulation in the viewport. Click this
button, and then drag vertically on any border to
extrude it.
