# Delete Duplicates: Remove Overlapping Objects

## Streamline Your Workspace by Identifying and Eliminating Duplicated Shapes

The **Delete Duplicates** feature in LightBurn identifies and removes identical, overlapping objects in your project. This tool ensures clean designs and eliminates issues caused by duplicate shapes, such as extra passes or unexpected engravings.

#### Where to Find Delete Duplicates

- **Menu Location:** Edit → Delete Duplicates
- **Keyboard Shortcuts:** 
    - **Windows:** Alt+D
    - **Mac:** Option+D

---

#### How It Works

**Delete Duplicates** automatically scans your project to detect and remove identical objects that overlap in size, shape, and position. You don’t need to select objects for the tool to work, but they must meet these criteria:

- Objects must be **Ungrouped.**
- Objects must be **identical in size, shape, and position.**

---

#### Using Delete Duplicates

1. Ensure all objects in your project are ungrouped.
2. Navigate to **Edit → Delete Duplicates** or press **Alt/Option+D.**
3. The tool will identify and remove overlapping duplicates, streamlining your project.

#### Why Use Delete Duplicates?

Duplicate objects can cause various issues in your design:

- **Filled Objects Appear as Outlines:** Duplicate shapes may render incorrectly in the workspace, even when **View Style** is set to Filled.
- **Objects Disappear in Preview:** Overlapping shapes can cause elements to vanish in the Preview window.
- **Engraving Errors:** Duplicates may lead to extra passes in **Line Mode** or engraving failures in **Fill Mode.**

---

#### Troubleshooting

If **Delete Duplicates** doesn’t detect or remove duplicates:

- Make sure the objects are **Ungrouped.** Grouped objects cannot be processed by this tool.

With **Delete Duplicates**, you can optimize your workspace and eliminate potential errors in your LightBurn designs. Incorporate this tool into your workflow for cleaner and more efficient projects.
