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 provides a m agnet-like effect with
a sphere of influence around the selection.

Edit Polygons/Elements rollout
At the element sub-object level, this rollout
includes commands that are common to both
polygons and elements. At the polygon level, it
containsthoseaswellasanumbermorethatare
unique to polygons. The commands available at
both levels are Insert Vertex, Edit Triangulation,
Retriangulate, and Flip.
Note: To delete polygons or elements, select them
and press the DELETE key. A dialog mi ght appear
asking if you want to delete isolated vertices, w h ich
are vertices that are used only by polygons or
elements that are to be deleted. Click Ye s to delete
them; click No to retain them.
Insert Vertex—Lets you subdivide polygons
manually. Applies to polygons, even if at the
element sub-object level.
After turning on Insert Vertex, click a p olygon to
add a vertex at that location. You can continue

To stop inser ting 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.
Ex trude—Lets you perfor m manual extrusion via
direct manipulation in the viewport. Click this
button, and then drag vertically on any polygon
to extrude it.

and creates new p olygons that form the sides of the
extrusion, connecting the selection to the object.
Following are important aspects of polygon
extrusion:
• When over a selected polygon, the mouse
cursor changes to an Extrude cursor.
• Drag vert ically to specify the extent of the
extrusion, and horizontally to set the size of the
base.
• With multiple polygons selected, dragging on
any one extrudes all selected polygons equally.
• You can drag other polygons in turn to extrude
them while the Extr ude button is active. Click
Extrude again or right-click in the active
viewport to end the operation.
