Straighten, smooth, curl or bend a curve
 
 
 
To... Do this

Straighten a curve.

Select the curve (or CVs) and choose Edit Curves > Modify Curves > Straighten.

Smooth a curve.

Select the curve (or CVs) and choose Edit Curves > Modify Curves > Smooth.

Curl a curve.

Select the curve (or CVs) and choose Edit Curves > Modify Curves > Curl.

Bend a curve.

Select the curve (or CVs) and choose Edit Curves > Modify Curves > Bend.

Reduce or exaggerate a curve’s curvature.

Select the curve (or CVs) and choose Edit Curves > Modify Curves > Scale Curvature.

TipBecause Straighten, Smooth, Bend, and Scale Curvature are actions that you apply to curves, you cannot interactively adjust their effect as you would with a tool. However, you can set the scaling of the tool very low (for example, set Straightness to 0.1) and repeatedly apply the action until the curve has the desired shape.
