Note:
Repeat Last does not repeat a ll operations.
For instance, it does not repeat transforms. To
determine which command is repeated when you
click the button, check the button’s tooltip. If no
tooltip appears, nothing will happen when it is
clicked.
Constra ints—Lets you use existing geometry to
constrain sub-object transformation. Use the
drop-down list to choose the constraint type:
• None: No constraints.
• Edge: Constrains vertex transformations to
edge boundaries.
• Face: Constrains vertex transformations to face
surfaces.
Note: YoucansetthisattheObjectlevel,butits
usage pertains primari ly to sub-object levels. The
Constraints sett ing persists at all sub-object levels.
Cr e ate —Lets you create polygons from isolated
vertices and border vertices. All vertices in the
object are highlighted.
Click three or more existing vertices in succession
to define the shape of the new polygon. ( T he
cursor changes to a cross when it is over a vertex
that can legitimately be part of the polygon.) To
finish polygon creation, double-click the last
vertex. You can also finish creating the polygon by
clicking any vertex of the new polygon a second
time. You can also create new polygons at the
Polygon and Element sub-object levels.
Youcanaddverticesinthismodeby
SHIFT+clicking in an empty space; these vertices
are incorporated into the polygon you’re creating.
Youcanstartcreatingpolygonsinanyviewport,
but all subsequent clicks must take place in the
same viewpor t.
Note: This is the same as Create at the
Polygon/Element level.
Tip: For best results, click vertices in
counterclockwise order. If you use clockwise
order, the new polygon will face away from you,

on Force 2-Sided or are using a two-sided material.
Attach—Lets you attach another object in the s cene
to the selected Edit Poly object. Click the object
youwanttoattachtothecurrentlyselectedEdit
Poly object.
You can attach any type of geometry object,
including splines and patch objects. Attaching a
non-mesh object converts it to Edit Poly format.
When you attach an object, the materials of t he
two objects are combined in the following way:
• If the attached object does not have a mater ia l
assigned, it inher its the material of the object it
is attached to.
Handle inherits material from the c up it is attached to.
• Likewise, if the object you’re attaching to
doesn’t have a mater ial, it inherits the mater ial
of the object being attached.
• If both objects have materia ls, the resulting
new material is a
multi/sub-object material
(page 2–1403)
that includes the i nput materials.
A dialog appears offering three methods of
combining the objects’ materials and material
IDs. For more information, see

A ttach remains active at all sub-object levels,
but always applies to objects.
