Refine—
Refines the curve by adding CVs.
Wa rning: When you add CVs with Refine, you lose the
animation controllers for all CVs on the curve.
As you move the mouse over the CV curve, a
preview of the CVs t h at will be added, and their
locations, is displayed in blue.
Tip: It is a good idea to reparameterize after you
have added CVs to a curve by refining. See Editing
Curve Sub-Objects (page 1–1135).
Delete—Deletes the selected CVs.
Insert—Inserts C Vs into the curve. Click Insert
and then click the curve w here you want to insert
the new CV. Inserting CVs is similar to refining
with CVs, except that other CVs in the curve do
not move. This means that the shape of the cu rve
changes when you insert.
Inserting CVs does not remove animation from
thecurve,asrefiningdoes.
Tip: It is a good idea to reparameterize after you
have added CVs to a curve by inserting. See
Editing Curve Sub-Objects (page 1–1135).
Extend—Extends a CV curve. Drag from the end
of a curve to add a new CV an d extend the curve.
Wa rning: When you add points with Extend, you lose
the animation controllers for all points on the curve.
Remove Animation—
Removes animation
controllers from the selected CVs.
Display L attice—When on, displays the control
lattice (page 3–923) that sur rounds C V curves.
When off, the control lattice isn’t shown in
viewports. Default=on.

are currently selected.

Procedures (page 1–1130)
Interface (page 1–1132)
This topic describes the controls for CV
sub-objects that lie on surfaces. A rollout labeled
CV contains the CV sub-object controls for
NURBS models. In addition to the CV rollou t
described here, the Curve CV sub-object level
displays the Soft Selection rollout (page 1–1147).
Procedures
To transform surfa ce CV sub-objects:
1.
At the Surface CV sub-object level, select one
or more CVs.
The sub-object selection tools are the same as
for other kinds of sub-objects. You can also
use the
H key while the Keyboard Shortcut
Override Toggle (page 3–872) button is on. See
Sub-O bject Selection (page 1–1084).
