Procedures (page 1–1132)
Interface (page 1–1134)
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 rollout
described here, the Curve CV sub-object level
displays the
Soft Selection rollout (page 1–1148)
.
Pr ocedur es
To transform sur face CV sub-objects:
1.
At the Surface CV sub-object level, select one
or more CVs.

for other k inds of sub-objects. You can also
use the H key wh ile the status bar’s Keyboard
Shortcut Override Toggle button is on. See
Sub-Object Selection (page 1–1086)
.
The Selection group box, described under
"Interface" later in this topic, provides
additional options for selecting CV sub-objects.
2. Turn on Move or another transform and then
drag in a viewport to transform the selection.

Rotate and Scale are useful only when you’ve
selected multiple CVs.
Tips
•
The Lo ck Selection Set button is useful
when you t ransform NURBS CV sub-objects.
You can make a selection in one viewport, click

over or under adjacent points. This can create
odd-looking warps or overlaps in the surface.
To SHIFT+clone surface sub-objects:
• Hold down SHIFT while you transform the
surface selection.
The
Sub-Object Clone Options (page 1–1239)
dialog appears. This dialog provides various
ways to clone the surfaces, some of which
reduce relational dependencies to improve
performance.
To use the k ey boar d to select sur f ace CV sub-objects:
You c an select surface CV sub-objects using the
CTRL key and the arrow keys. The arrows traverse
the sub-objects in the order they were create d. To
do so, follow these steps:
