See Editable Poly (page 1–1025) for information on
the Selection rollout settings.
Soft Sele ction rollout
Soft Selection controls apply a smooth falloff
between selected sub-objects and unselected
ones. When Use Soft Selection is on, unselec ted
sub-objectsnearyourselectionaregivenpartial
selectionvalues. Thesevaluesareshowninthe
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 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.
For more information, see Soft Selection Rollout
(page 1–963).
Edit Vertice s rollout
This rollout includes commands specific to vertex
editing.
Note: To delete vertices, select them and press the
Delete key. This can create one or more holes
in the mesh. To delete vertices without creating
holes, use Remove (see below).
Remove—Deletes selected vertices and combines
the polygons that use them. The keyboard shortcut
is
Backspace .
Removing one or mo re vertices deletes them and retriangulates
the mesh to keep the surface intact. If you use D elete instead,
the polygons depending on those vertices are deleted as well,
creating a hole in the mesh.
Wa rn in g : Use of Remove can result in mesh shape
changes and non-planar polygons.
Break—
Creates a new vertex for each polygon
attached to selected vertices, allowing the polygon
corners to b e moved away from each other where
they were once joined at each original vertex. If a
vertex is isolated or used by only one polygon, it
is unaffected.
Ex trude—Lets you extrude vertices manually v ia
direct manipula tion in the viewport. Click this
button, and then drag ver tically on any ver tex to
extrude it.
Extruding a vertex moves it along a normal and
creates new polygons that form the sides of the
extrusion, connecting the vertex to the object.
The extrusion has the same number of sides as
the number of polygons that originally used the
extruded vertex.
Following are important aspects of vertex
extrusion:
• When over a selected vertex, the mouse cursor
changes to an Extrude cursor.
• Drag vertically to specif y the extent of the
extrusion, and horizontally to set the size of the
base.
• With multiple vertices selected, dragging on
any one extrudes all selected ver t ices equally.
