306 Chapter 5: Creating Geometry
After turning on Connect and before b eginning
the refinement process, turn on any combination
of these options:
•
Linear—When on, makes all segments in the
new spline linear by using Corner vertices.
When Linear is off, the vertices used to create
the new spline are of the Smo oth type.
•
Bind First—Causes the first vertex created in a
refinement operation to be bound to the center
of the selected segment.
For more information, see Bound Vertex (page
3–919).
•
Clo sed —When on, connects the first and last
vertices in the new spline to create a closed
spline. When Closed is off, Connect always
creates an open spline.
•
Bind Last—Causes the last vertex created in a
refinement operation to be bound to the center
of the selected segment.
For more information, see Bound Vertex (page
3–919).
Connect Copy group
Connect Copy—When on, Shif t +Cloning a
segment creates a new spline sub-object with
additional splines that connect the new segment’s
vertices to the vertices of the original segment. It
is analogous to
Shif t +Cloning edges in Editable
Mesh and Editable Poly objects.
Note: For Connect Copy to work, you must turn it
on before you
Shif t +Clone.
Threshold— Determinesthedistancesoftselection
will use when Connect Copy is on. A higher
threshold results in more splines b eing created; a
lower threshold results in fewer splines.
End Point Auto-Welding group
Automatic Welding—When Automatic Welding is
turned on, an end point vertex that is placed or
moved within the threshold distance of another
endpointofthesamesplineisautomatically
welded. This feature is available at the object and
all sub-object levels.
Threshold—T he threshold distance spinner is a

Insert—Inserts one or more vertices, creating
additional segments. C lick anywhere in a seg ment
to insert a vertex and attach the mouse to the
spline. Then optionally move the mouse and
click to place the new vertex. Continue moving
the mouse and clicking to add vertices. A single
click inserts a corner vertex, while a drag creates a
Bezier (smo oth) vertex.
Right-click to complete the operation and release
the mouse. At this point, you’re still in Insert
mode, and can begin inserting vert ices in a
different segment. Otherwise, r ight-click again or
click Insert to exit Insert mode.
