| geometryCombineMode(value: GeometryCombineMode) | Sets the GeometryCombineMode property.                                 |
| reference(value: ViewRef)                       | Link a ViewRef to access the direct CombinedGeometry control instance. |

## Usages

```fsharp
CombinedGeometry(RectangleGeometry(Rect(10., 10., 100., 100.)), EllipseGeometry(50., 50.).center(Point(50., 50.)))
    .geometryCombineMode(GeometryCombineMode.Union)
```

#### Get access to the underlying CombinedGeometry

```fsharp
let geometryRef = ViewRef<CombinedGeometry>()

CombinedGeometry(RectangleGeometry(Rect(10., 10., 100., 100.)), EllipseGeometry(50., 50.).center(Point(50., 50.)))
    .geometryCombineMode(GeometryCombineMode.Union)
    .reference(geometryRef)
```
