# [name]

Creates extruded geometry from a path shape.

## Code Example

`const length = 12, width = 8; const shape = new THREE.Shape(); shape.moveTo( 0,0 ); shape.lineTo( 0, width ); shape.lineTo( length, width ); shape.lineTo( length, 0 ); shape.lineTo( 0, 0 ); const extrudeSettings = { steps: 2, depth: 16, bevelEnabled: true, bevelThickness: 1, bevelSize: 1, bevelOffset: 0, bevelSegments: 1 }; const geometry = new THREE.ExtrudeGeometry( shape, extrudeSettings ); const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); const mesh = new THREE.Mesh( geometry, material ) ; scene.add( mesh );`

## Constructor

### [name]([param:Array shapes], [param:Object options])

shapes — Shape or an array of shapes.
options — Object that can contain the following parameters.

- curveSegments — int. Number of points on the curves. Default is `12`.
- steps — int. Number of points used for subdividing segments along the depth of the extruded spline. Default is `1`.
- depth — float. Depth to extrude the shape. Default is `1`.
- bevelEnabled — bool. Apply beveling to the shape. Default is true.
- bevelThickness — float. How deep into the original shape the bevel goes. Default is `0.2`.
- bevelSize — float. Distance from the shape outline that the bevel extends. Default is bevelThickness - 0.1.
- bevelOffset — float. Distance from the shape outline that the bevel starts. Default is `0`.
- bevelSegments — int. Number of bevel layers. Default is `3`.
- extrudePath — THREE.Curve. A 3D spline path along which the shape should be extruded. Bevels not supported for path extrusion.
- UVGenerator — Object. object that provides UV generator functions

This object extrudes a 2D shape to a 3D geometry.

When creating a Mesh with this geometry, if you'd like to have a separate material used for its face and its extruded sides, you can use an array of materials. The first material will be applied to the face; the second material will be applied to the sides.

## Properties

See the base [page:BufferGeometry] class for common properties.

### [property:Object parameters]

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.

## Methods

See the base [page:BufferGeometry] class for common methods.
