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 Edit Poly Border sub-object level, you can
select sing le and multiple b orders and tr ansform
them using standard methods. This topic covers
the Edit Geometry and Edit Borders rollouts;
for other controls, see
Edit Poly Modifier (page
1–619)
.
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 Edit Borders rollout > Cap.

viewports by means of a color gradient on the
vertices, and optionally on the faces. They affect
most types 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.
Extrudingabordermovesitalonganormaland
creates new polygons that form the sides of the
extrusion, connecting the border to the object.
The extrusion can form a varying number of
additional sides, depending on the geometry
near the border. As you increase the length of the
extrusion, the base increases in size, to the extent
of the vertices adjacent to the extruded border’s
endpoints.
Important aspects of border extrusion are:
• The mouse cursor changes to an Ext rude cursor
when over a selected border.
