### 9.4.6. Transformation: Reflection

The Reflection method is used to mirror a mesh in a specified plane. Apart from using the principal planes (for example, the XY plane), arbitrary planes can be created with the Three Points and the Point and Normal methods. These are the same plane definition methods that are available in CFD-Post.

#### 9.4.6.1. Method

The options available are `YZ Plane`, `XZ Plane`, `XY Plane`, `Three Points` and `Point and Normal`.

When using the `YZ Plane`, `XZ Plane`, or `XY Plane` method, an offset can be applied by entering values in the X, Y, Z offset box.

If you use the `Three Points` or `Point and Normal` method, the points can be manually entered or selected in the viewer after you click in any coordinate field.

#### 9.4.6.2. Apply Reflection To

This setting controls whether the transformation is applied to the original mesh or to a copy of the mesh. If you have set up physics locations on the original mesh, such locations are retained after the transformation.

The following options are available:

`Original (No Copy)`

  Transforms the original mesh without making a copy.

`Copy (Keep Original)`

  Copies the original mesh before applying the transformation. In this case, the original mesh remains in its current location.
