Editing Curve Sub-Objects 1137
The Sub-Object Clone Opt ions (page 1–1239)
dialog is displayed. This dialog provides
various ways to clone the curves, some of which
reduce relational dependencies to improve
perfor mance.

Yo u c a n s e l e c t c u r v e s u b - o b j e c t s u s i n g t h e CTRL
key and the arrow keys. The arrows traverse the
sub-objects in the order they were c reated. To do
so, follow these steps:
1. Tu r n on th e Ke y bo ard Sh or tcut
Override Toggle.
2. At the Curve sub-object level, set the
selection controls to select curves individually.
3. Click or drag to select cur ves.
4. Hold down CTRL and use the ar row keys to
move among the curves in the current model.
At the Curve sub-object level, the left and
right arrow keys move forward and backward
through individual curves in the order they
were created. The up and down arrows are
equivalent to left and right.
Yo u c a n a l s o u s e t h e H keyboard shortcut (w hi le

CTRL+H displays only the names of curves
directly beneath the mouse cursor.
To delete a curve:
• Select the curve and then click D elete.

ToturnaCVcurveintoapointcurve:
1.
Select the cur ve sub-object, and then click
Make Fit.
The
Make Point Curve (page 1–1237) dialog is
displayed. This dialog asks how many points
the new point curve should have.
2. Change the number of points, and then click
OK.
Reducing the number of points can change the
shape of the curve.
If the selected curve is already a point curve, you
can u se Make Fit to change the number of points
it has.
To select a first ver tex on the curve:
• Select the cur ve sub-object, turn on Make First,
andthenclickalocationonthecurve.
If the cur ve is close d and there is a vertex w here
you click, this vertex becomes the first vertex. If
the curve is closed and there is no vertex where
you click, a new vertex is created at the location
you click. It becomes the new first vertex, and
the curve’s points or CVs adapt to maintain the
curvature.
If the curve is open, clicking it has no effect.
Wa rni ng: Using Make First discards any animation
controllers for the points or CVs in t he curve.
If the curve is open, the first vertex must be one
oftheendpoints(bydefault,itisthefirstyou
created). The Make First button has no effect,
but you can use Reverse to change the curve’s
direction.
