title: Twist & Bend
order: 8
---

Two simple deformers that warp a shape along an axis. The result stays smooth and watertight, so you can keep adding booleans, mirrors, or rounding on top.

Both are added from *Add Modifier*, the pie or the right-click menu, and go onto **every selected shape** at once. The buttons grey out, with a reason in the tooltip, when nothing suitable is selected. The axis passes through the object's origin; see [The origin is the pivot](index.md#modifier-ui-tips).

## Twist

Rotate the SDF along an axis at a constant rate.

![Twist settings](../assets/modifiersettings-twist.webp)

- **Axis**: X / **Y** / Z (default Y)
- **Strength**: radians per unit distance along the axis (`-10.0–10.0`, default `1.0`). Negative values twist the other direction.

Combine Twist with [Array](array.md) or [Mirror](mirror.md) to build helices, screws, augers, and decorative columns.

## Bend

Curve the SDF around an axis. Higher strength = tighter bend.

![Bend settings](../assets/modifiersettings-bend.webp)

- **Axis**: X / Y / **Z**
- **Strength**: bend curvature amount (`-10.0–10.0`, default `1.0`)

Bend is useful for making horns, tubing, arched panels, and bow shapes from straight primitives.

## Stacking deformers

Both Twist and Bend are deformations of the underlying field, as are [Revolve](revolve.md), [Sweep](sweep.md) and [Lattice](lattice.md). They stack in the modifier list, so you can chain *Bend → Twist → Mirror* to build complex helical-curved-symmetric shapes from a single primitive.

Order matters. *Twist before Bend* gives a helically-twisted bend; *Bend before Twist* gives a curved arc that twists around itself.
