This topic describes the controls for CV
sub-objects that lie on curves. 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 1–1147).
In you can edit the CVs in CV curves on surfaces
(page 1–1172) as you edit other kinds of curve
CVs. You c an transform CVs in CV cur ves on
surfaces, but you can’t move the CVs off the
surface. Using the Curve CV sub-object level is an
alternativetoeditingtheseCVsbyusingtheEdit
Curve on Surface (page 1–1229) dialog.
Pr ocedur es
To tr ans for m cur ve CV sub-objects:
1.
At the Curve 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) is on. See
Sub-Object Selection (page 1–1084).
The Selection group box, described under
"Interface" later in this topic, provides some
additional options for selecting CV sub-objects.
2. Turn on Move or another transform and then
drag in a viewport to transform the selection.
Theshapeofthemodelchangesasyou
int eractively transform the CVs.
Rotate and Scale are useful only when you’ve
selected multiple CVs.
Tips
•
When you transform NURBS CV
sub-objects, the Lock Selection Set button can
beuseful. Youcanmakeaselectioninone
viewport, click Lo ck Selection Set (or press the
Spacebar ), and then t ransform the selection
in a different viewport.

Ctrl key and the arrow keys. The arrows traverse
the sub-objects in the order they were created. To
do so, follow these steps:
1. Turn on the Keybo a rd Shor tc ut
Override Toggle.
2. Click or drag to select CVs.
3. Hold down Ctrl and use the arrow keys to
move among t he CV sub-objects.
For CVs on curves, the arrow keys traverse the
CV selection along the length of the curve.
The arrow keys don’t move between curve
sub-objects.
