# PHASEShape.Element

An object that describes the characteristics of a physical surface.

## Declaration

```swift
class Element
```

## Overview

Overview This class defines the material that makes up a PHASEShape object. You don’t instantiate instances of this class yourself; the framework creates an instance of this class for every material you pass into the init(engine:mesh:materials:) initializer. The shape’s elements array provides read-only access to the instances.
