# Pinch

### Intro

The **Pinch Deformer** can be used to sculpt Shapes.

### UI

[Common Attributes](/cavalry/nodes/behaviours/common-attributes-behaviours.md) +

**Active** - enable/ disable the Deformer. This is useful when initially placing the Falloffs for **Bind Area** and **Pinch Point**.

**Bind Area** - the area where the **Pinch** is active. By default, when you create a Pinch Deformer a [Falloff](/cavalry/nodes/utilities/falloff.md) called **Pinch Binder** is added and connected to this attribute. Any shape points falling within this Falloff will be affected with any outside being ignored.

**Pinch Point** - by default, a [Null](/cavalry/nodes/utilities/null.md) called **Pinch Mover** is created and connected to this attribute when creating a Pinch Deformer. This Null can then be repositioned to 'pinch' the Shape it is deforming.

{% hint style="info" %}
Example usage:

1. Create an [Ellipse](/cavalry/nodes/shapes/basic-shape.md)
2. Set **Radius** to W = 300, H = 300.
3. Uncheck **Bezier**.
4. Using the `+` icon on the **Deformer** attribute, select **Pinch** from the list.
5. Move the **Pinch Binder** [Falloff](/cavalry/nodes/utilities/falloff.md) so its centre is over the edge of the Ellipse.
6. Move the **Pinch Mover** [Null](/cavalry/nodes/utilities/null.md).

The part of the Ellipse within the Falloff is deformed. Try increasing the size of the **Pinch Binder** Falloff or adjusting its **Falloff Graph**.
