vertices, and optionally on the faces. They affect
most types of sub-object deformations, such as the
Move, Rotate, and Scale functions, as well as any
deformation modifiers (such as Bend) applied to
the object. This prov ides a magnet-like effect with
a sphere of influence around the selection.

(page 1–963).
Edit Edges ro llout
This rollout includes commands specific to edge
editing.
Note: To delete edges, select them and press the
Delete key. This deletes all selected edges and
attached polygons, which can create one or more
holes in the mesh. To delete edges without creating
holes, use Remove (see following entry).
Insert Ver tex—Lets you subdivide visible edges
manually.
After turning on Insert Vertex, click an edge to
add a vertex at that location. You can continue
subdividing polygons as long as the command is
active.
To stop inserting edges, right-click in the viewport,
or click Insert Vertex again to turn it off.
Remove—Deletes selected edges and combines the
polygonsthatusethem.Thekeyboardshortcutis
Backspace .
Removing one edge is like making it invisible. The mesh
is affected only when you remove all but one of the edges
depending on o ne vertex. At that point, the vertex itself is
deleted and the surface is retriangulated.
To delete the associated vertices as well, press and
hold
Ct rl while executing a Remove operation,
either by mouse or with the
Backspace key . This
option, called Clean Remove, ensures that the
remainingpolygonsareplanar.
Left: The original edge selection
Center: Standard Remove operation leaves ex tra vertices.
Right: Clean Remove with
Ctrl +Remove deletes the extra
vertices.
Edges with the same polygon on both sides usually
can’t be removed.
Wa rn in g : Use of Remove can result in mesh shape
changes and non-planar polygons.
Split—
Divides t he mesh along the selected edges.
Split does nothing when applied to a single edge in
themiddleofamesh. Theverticesattheendof
affected edges must be separable for this option
to work. For example, it would work on a single
edge that intersects an exist ing border, since the
border vertex can be split in two. Additionally, two
adjacent edges could be split in the middle of a
grid or sphere, since the shared vertex can be split.
Ex trude—Lets you extrude edges manually via
direct manipula tion in the viewport. Click this
