Editable Poly (Border) 1045
Note:
To delete a border, select it and press the
Delete key. This deletes the border and all
attached polygons.
Extrude—Lets you extr ude 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 extr usion can form a varying number of
additional sides, depending on t he 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.
Following are import ant aspec ts of b order
extrusion:
• When over a selected border, the mouse c ursor
changes to an Extrude cursor.
• Drag vertically to specify the extent of the
extrusion, and horizontally to set the s ize of the
base.
• With multiple borders selected, dragging on
any one extrudes all selected borders equally.

them while the Extrude button is active. Click
Extrude again or ri ght-click in the active
viewport to end the operation.
Ex trude S ettings—Opens the Extrude Edges
dialog (page 1–1073),whichletsyouperform
extrusion via interactive manipulation.
If you click this button after performing a manual
extrusion, the same extrusion is performed on the
current selection as a preview and the dialog opens
w ith Extrusion Height set to the amount of the last
manual ext r usion.
Insert Vertex—Lets you subdivide border edges
manually.
After turning on Insert Vertex, click a border edge
to add a vertex at that location. You can continue
subdividing border edges as long as the command
is active.
To stop inserting vertices, right-click in the
viewport, or click Insert Vertex again to turn it off.
Note: In previous versions of the software, this
command was called Divide.
Chamf e r—Click this button and then drag a border
in the ac tive object. The border need not be
selected first.
If you chamfer multiple selected borders, all of
them are chamfered identically. If you drag an
unselected b order, any selected borders are first
deselected.
A border chamfer essentially “frames” the border
edges, creating a new set of edges paralleling the
border edges, plus new diagonal edges at any
corners. These new edges are exactly <chamfer
amount> distance from the original edges. New
chamfer faces are created with the material ID of
one of the neighboring faces (picked at random)
and a smoothing group which is an intersection of
all neighboring smo othing groups.
Alternatively, you can create open space around
the chamfered borders, essentially cutting away
at the open edges; for details, see Chamfer Edges
dialog (page 1–1070).
Chamfer S ettings—Opens the Chamfer Edges
dialog (page 1–1070), which lets you chamfer
borders via interactive manipula tion and toggle
the O pen option.
If you click this button after performing a manual
chamfer, the same chamfer is performed on the
current selection as a preview and the dialog opens
