Top: The original vertex selection
Center: Vertices chamfered
Bottom: Vertices chamfered with Open on
Chamfer S ettings—Opens the Chamfer Ver tices
dialog (page 1–1071)
, which lets you chamfer
ver t ices via interactive manipulation and toggle
the Open option.
If you click this button af ter performing a manual
chamfer, the same chamfer is performed on the
current selection as a preview and the dialog opens
w ith Chamfer Amount set to the amount of the
last manual extrusion.
Target Weld—Allows you to select a vertex and
weld it to a neighboring target vertex. Target Weld
works only with p airs of contiguous vertices; that
is, vertices connected by a single edge.
In Target Weld mode, the mouse cursor, when
positioned over a vertex, changes to a + cursor.
Click and then move the mouse; a dashed,
rubber-band line connects the vertex to the
mousecursor.Positionthecursoroveranother,
neighboring vertex and when the + cursor appears
again, click the mouse. The first vertex is moved to
the position of the second, the two are welded, and
Target Weld mode is automatically exited.
Co nnect—Creates new edges between pairs of
selected vertices.
Connectwillnotletthenewedgescross.Thus,
for example, if you select all four vertices of a
four-sided polygon and then click Connect, only
two of the vert ices will b e connected. In this case,
to connect all four vertices with new edges, use
Cut .
R emov e I s ol a ted V ert i ces—Deletes all vertices that
don’t belong to any polygons.
Remove Unused Map Verts—Certain modeling
operations can leave unused (isolated) map
vertices that show up in the
Unwrap UVW editor
(page 1–878)
, but cannot be used for mapping.
You can use this button to automatically delete
these map vertices.
Weigh t—Sets the weight of selected vertices. Used
by the
NURMS subdivision option and by the
MeshSmooth modifier (page 1–714) .Increasing
a vertex weight tends to pull the smoothed result
toward the vertex.
