# Calculate Geometry Difference Activity

## Description

Calculates the difference of two geometries.

## Usage

You may need to find the difference between two geometries. You could find the difference in geometries and then use the Calculate Area or Calculate Length activity to find out how much larger one geometry is than the other.

## Inputs

Geometry |

The input geometry to subtract from. |

Subtractor |

The geometry being subtracted from inclusion. |

Symmetric |

Whether the difference is symmetric or not. If true, the symmetric difference between leftGeometry and rightGeometry is returned. Otherwise, rightGeometry is subtracted from leftGeometry. |

## Outputs

geometry |

The first difference result. |
