Ctrl+H displays only the names of CVs directly
beneath the mouse cursor.
To remove a CV from a cur ve:
1.
Select a CV.
2. Click Delete.
Keyboard shortcut:
Delete
TheCVisdeletedandtheshapeofthecurve
is updated.
Note: A CV curve must have at least one more
CV than the degree (page 3–927) of the curve.
To add a CV to a curve:
1.
Turn on Refin e.
2. Click the curve where you want to add the CV.
A CV is added at the location you clicked.
Neighboring C Vs move away from the new CV
in order to preserve the original curvature.
ToaddCVsandextendthelengthofacurve:
1.
ClicktoturnonExtend.
2. Move the mouse over a CV curve. The curve is
highlighted in blue, and one of the curve’s ends
displays a box to show where the curve will be
extended.
3. Drag f rom the highlig hted end CV, and then
release the mouse button.

To fuse two CVs:
1.
Turn on Fuse .
2. Click a CV without releasing the mouse button.
Drag to another C V, and then release the mouse
button.
ThefirstCVyouchooseacquirestheposition
of the second CV, and becomes dependent to it.
If the first CV has a n a nimation controller, t he
controller is discarded. If the second CV has
an animation controller, the first CV acquires
it too .
Fused CVs display in purple by default.
To unfuse fused CVs:
1.
Select the fused CV.
2. Click Unfuse.
Now you can move and edit the two CVs
independently.
To t ra nsfor m a regi on:
1.
Using sub-object selection, select one or more
CVs for the center of transformation.
2. Tur n on Soft Selection.
3. Tr ansform the CV.
A region around the selected CV is transformed
accordingly.
Move is the most common transform to use.
Rotate and Scale can be used w ith a non-local
transform center.
Tip: If Soft Select ion appears not to be working,
the Falloff value mig ht be too small for the size
of your surface. On the Soft Selection rollout
(page 1–1147), inc rease the value of Falloff so it
encompasses other points or CVs.
Interfa ce
In addition to the CV rollout described here, the
Curve CV sub-object level also displays the Soft
Selection rollout (page 1–1147).
