public class LinearExtrusion extends Entity implements IMeshConvertible
```

Linear extrusion takes a 2D shape as input and extends the shape in the 3rd dimension. **Example:** The following code shows how to use LinearExtrusion to extrude a shape into a solid model.

```
//Create a new 3D scene
 		Scene scene = new Scene();
 
 		// Initialize the base profile to be extruded
 		var profile = new RectangleShape();
 		profile.setRoundingRadius(0.3);
 
 		// Create left node
 		var left = scene.getRootNode().createChildNode();
 		left.createChildNode(new Box(0.01, 3, 3));
 
 		// Create right node
 		var right = scene.getRootNode().createChildNode();
 		right.createChildNode(new Box(0.01, 3, 3));
 		right.getTransform().setTranslation(new Vector3(5, 0, 0));
 
 		//Perform linear extrusion on left node using center and slices property
 		var l = new LinearExtrusion(profile, 10);
 		l.setCenter(false);
 		l.setSlices(3);
 		l.setTwist(20);
 		left.createChildNode(l);
 
 		// Perform linear extrusion on left node using center and slices property
 		var r = new LinearExtrusion(profile, 10);
 		r.setCenter(true);
 		r.setSlices(3);
 		r.setTwist(90);
 		right.createChildNode(r);
