# CapturedRoom.Surface.Curve

An object that represents a single curve of a surface.

## Declaration

```swift
struct Curve
```

## Overview

Overview Each CapturedRoom.Surface instance in a captured room’s surface arrays (doors, openings, walls, and windows) that models a curved real-world surface contains an optional property (curve) of this type.
