# Parenting Masks

You can add an axis to the scene and then make it the parent of another element. Use this method of parenting additional axes to create complex wipes.

For example, you can create two masks that change shape and size independently but are parented to another axis translation in the same direction at a constant rate.

To create a branch:

1. Add an axis (axis2) to the scene.
2. In the World View box, select Schematic view. The Schematic view should be similar to the Before figure in step 4.
3. Select Parent in the Edit Mode box.
4. Drag the cursor from axis2 to axis1. Axis2 becomes the parent of axis1, as shown in the After figure.

   Before: The schematic shows axis1 as the parent of geom1. | After: Axis2 is made the parent of Axis1 (and geom1) using Parent mode.

Any transformations applied to axis2 are applied to axis1 and its surface (image1). If axis1 has any transformations, they are added to the transformations from axis2. For example, if axis2 is set to 500, 100, 0 and axis1 is set to -50, 20, -30, the positions are accumulated and applied to the surface. In this case, image1 is positioned at 450, 120, -30.
