# Mastering the Cut Shapes Tool in LightBurn

## A Step-by-Step Guide to Dividing Shapes with Precision

The Cut Shapes tool in LightBurn divides selected vector objects into separate shapes using another closed shape as the cutting tool. The tool enables precision editing and is especially useful for creating sections in projects larger than your laser's workspace.

1. **Select the Shapes:**  
   Choose the shapes you want to cut. Add the cutting tool shape to your selection last.
2. **Activate the Tool:**  
   Navigate to **Tools → Cut Shapes** or use the shortcut **Alt/Option + Shift + C**.

3. **Process the Cut:**  
   LightBurn uses the last selected shape as the cutting tool and divides the other shapes where they intersect with it.
4. **Resulting Shapes:**
   
     - The shapes inside and outside the cutting tool are grouped separately.
     - Closed shapes are created for objects with **Fill** or **Offset Fill layers**, while **Line** or **Tool layers** remain open.

### Key Tips for Success

- **Closed Shape as the Tool:** The cutting shape must be a complete, continuous loop with joined start and end points.
- **Ungroup Before Cutting:** Ensure the cutting tool shape is not grouped with other objects.
- **Duplicate for Reuse:** If you want to retain the cutting tool shape, duplicate it before cutting.

### Using Cut Shapes with Images

When used with an image:

- LightBurn creates two masked copies of the image.
- One copy shows the portion inside the cutting shape; the other shows the portion outside.
- The cutting shape is duplicated and reassigned as a **Tool layer**.

### Troubleshooting

**Issue:** Cut Shapes is grayed out in the Tools menu.  
**Solution:**

- Verify the cutting tool is a closed shape.
- Ensure the cutting tool is not grouped with other objects.

### Cut Shapes Demo and Examples

To better understand the functionality, explore these examples:

- **Line vs. Fill:** Compare how shapes on Line vs. Fill layers behave after cutting.
- **Images:** See how images are divided and masked for precision editing.

By mastering the Cut Shapes tool, you'll unlock greater flexibility in designing intricate projects and managing complex layouts.
