# Boundary Slicer Tool

## How to slice existing boundaries in the GXLab 'Boundary Editor'

The **“Slice”** tool is used to create segments within a single boundary while keeping them grouped under the same boundary in GXLab. For example, it may be used to divide a grazing area into paddocks or split a cropping field where plant varieties differ. Follow the steps below and refer to the images for an example:

**1.** Open your project in the Upgraded Boundary Editor platform (GMS) by clicking the **“Try it now”** button under the *Boundary Setup* tab on the left.

**2.** Once your project is open in the Boundary Editor platform, click on the boundary you wish to slice.

**3.** In the panel on the right side of the screen, locate the **“Slicer”** tool (found in the middle of the toolbar).

**4.** Select the Slicer tool, then click on either side of the boundary to draw a slicing line through it.

- Continue clicking to create multiple slice lines if needed.

**5.** When you’re finished:

- Click **“Apply”** to confirm the slices (they will appear within the boundary area), or
- Click **“Cancel”** to discard the slice lines.
