The Yard Bay also has a distinct dependent layer. To customize the irregular end bays, select the editable layer in the Nav Tree. Next, rename the layer if required by double clicking on the layer in the Nav Tree. ![](https://support.testfit.io/hs-fs/hubfs/image-png-Feb-12-2025-01-24-09-5816-PM.png?width=670&height=234&name=image-png-Feb-12-2025-01-24-09-5816-PM.png) Adjust the Edge Depth and Left or Right Outset as required. ![](https://support.testfit.io/hs-fs/hubfs/image-png-Feb-12-2025-01-24-43-5521-PM.png?width=299&height=489&name=image-png-Feb-12-2025-01-24-43-5521-PM.png) Assign the appropriate Yard Type by utilizing the dropdown menu. ![](https://support.testfit.io/hs-fs/hubfs/image-png-Feb-12-2025-01-25-08-1500-PM.png?width=301&height=215&name=image-png-Feb-12-2025-01-25-08-1500-PM.png) To add an End Bay, Dock, Yard, or Green Buffer, click on the Data Centers preset layer in the Nav Tree.
