• Drag vertically to specify the extent of the
extrusion, and horizontally to set the size of the
base.
• With multiple edges selected, d r ag ging on any
one extrudes all selected edges equally.

If you click this button af ter 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 extrusion.
Weld—Combines selected edges that fall within
the threshold specified in the
Wel d d i a l o g ( p age
1–1078)
.
You can weld only edges that have one polygon
attached; that is, edges on a b order. Also, you
cannot perform a weld operation that results in
illegal geometry, such as an edge shared by more
than two polygons. For example, you cannot weld
opposite edges on the border of a box that has a
side removed.
Weld S ettings—Opens the Wel d dia lo g ( p age

, which lets you specify the weld threshold.
Chamf e r—Cl ick this button and then drag edges in
the active object. To chamfer vertices numerically,
click the Chamfer Settings button and change the
Chamfer Amount va lue.
If you chamfer multiple selected edges, all of
them are chamfered identically. If you drag an
unselected edge, any selected edges are first
unselected.
An edge chamfer "chops off" the selected edges,
creating a new polygon connecting new points on
all v isible edges leading to the original vertex. The
new edges are exactly <chamfer amount> distance
fromtheoriginaledgealongeachoftheseedges.
New chamfer faces are created with the materia l
ID of a neig hboring face (picked at random) and
a smoothing group that is an intersection of all
neighboring smoothing groups.
Forexample,ifyouchamferoneedgeofabox,
each corner vertex is replaced by two vertices
moving along the visible edges that lead to the
corner. Outside faces are rearranged and split
to use these new vertices, and a new polygon is
created at the corner.
Alternatively, you can create open space
arou nd the chamfered edges; for details, see
Chamfer Edges dialog (page 1–1071) .
Chamf e r Sett i n g s —Opens the Chamfer Edges
dialog (page 1–1071)
, which lets you chamfer
edges via interactive manipulation and toggle the
Open 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
with Chamfer Amount set to the amount of the
last manual chamfer.
Target Weld—Allows you to select an edge and
weld it to a target edge. When positioned over an
