Curve used to create a transform curve
Procedure
To creat e a transform curve:
• In a NURBS object that contains at least
one curve, tur n on Transform.
To move the transform curve, click and drag
the cu rve you want to
duplicate. To rotate or
scale the transform cu rve, click the parent
curve,clicktoturnonSub-Objectonthe
Modifier Stack rol
lout, choose Curve from the
drop-down list, and then use a transform to
rotate or sca le the transform curve.
When you use Move to create the transform
cur ve, it simply c
opies the parent. (It doesn’t
exaggerate curvature as an offset curve does.)
Axis constraints don’t apply to the creation of
transform curves. You can click to create the
curveinplace;thenonceitiscreated,transform
it using constraints.
Tip: You can also use axis constraints by using
SHIFT+cloneattheCurvesub-objectlevel.

Creation time
At creation time, transform curves have no
parameters.
Transform Curve rollout (modification time)
At modification time, you can transform the
transform curve as a cur ve sub-object, and you can
animate curve sub-object t r ansforms. Transform
curves also have one control in the Modify panel.
Replace Base Curve—Lets you replace the parent
curve. Click the button, t hen click the curve to
replace the original curve.
Blend Curve

Create Blend Curve button
A blend curve connects the end of one curve to
the end of another, blending the curvature of
the parents to create a smooth curve between
them. You can blend curves of the same type, a
point curve with a CV curve (and vice versa), an
independent curve with a dependent curve, and
so on.
