Twist deformation lets you create objects that spiral or twist along their length. Twist specifies the amount of rotation about the path.

Using twist to deform the lofted roadway

These are the properties of Twist deformation curves:

A single red curve determines shape rotation about the path.
The default curve value is 0 degrees of rotation.
Positive values produce counterclockwise rotation, when viewed from the start of the path.
Negative values produce clockwise rotation.
Both twist deformation and banking produce rotation about the path. Twist rotation is added to a shape after the banking angle is applied. You can use Twist deformation to exaggerate or reduce the amount of banking.

See Deformation Dialog for specific information on the dialog controls.
