Edit Curves > Modify Curves > Curl

Makes the selected curves (or selected CVs) curly so they resemble a helix. The curve’s first CV will maintain its original position.

Tip

Do not apply Curl to a curve twice. The second Curl will produce poor results because it is trying to curl a curve that is already curly.

Curl Amount: Determines how much each segment of the selected curves will be curled. The higher the Curl Amount, the greater the effect. The effect will be greater on a curve with many CVs than on a curve with few CVs because the Curl Amount affects each segment.
Curl Frequency: Determines how many curls the selected curves will be curled into.
