# GeometryCombineMode Enum

## Definition

Specifies the different methods by which two geometries can be combined.

public enum class GeometryCombineMode
public enum GeometryCombineMode
type GeometryCombineMode =
Public Enum GeometryCombineMode
Inheritance
GeometryCombineMode

## Fields

 Exclude 3 The second region is excluded from the first. Given two geometries, A and B, the area of geometry B is removed from the area of geometry A, producing a region that is A-B. Intersect 1 The two regions are combined by taking their intersection. The new area consists of the overlapping region between the two geometries. Union 0 The two regions are combined by taking the union of both. The resulting geometry is geometry A + geometry B. Xor 2 The two regions are combined by taking the area that exists in the first region but not the second and the area that exists in the second region but not the first. The new region consists of (A-B) + (B-A), where A and B are geometries.

## Examples

The following example shows how to combine two geometries using the Union combine mode.
