Mirror creates a flipped copy of your model along a chosen axis and optionally merges it with the original. Useful for creating symmetrical objects or duplicating parts.

## When to use this

* Creating a left-hand version from a right-hand part
* Building symmetrical objects from one half
* Duplicating a model in the opposite direction

## Settings

### Axis

**X**, **Y**, or **Z** — the axis to mirror along.

### Spacing (mm)

The gap between the original and the mirrored copy. When **Auto Offset** is on, this is the spacing used to keep the two halves from overlapping. Default: 2.

### Merge

Toggle (default: on). Combines the original and mirrored copy into a single printable object.

### Flip UVs

Toggle (default: off). Also mirrors the texture coordinates. Enable if the mirrored side's textures look wrong.

## Step by step

<Steps>
  <Step title="Select the Mirror tool">
    Click **Mirror** in the Interactive Tools section.
  </Step>

  <Step title="Choose the axis">
    Select X, Y, or Z.
  </Step>

  <Step title="Adjust spacing if needed">
    Set the **Spacing** to control the gap between the original and the mirrored copy.
  </Step>

  <Step title="Apply">
    Click **Apply** to create the mirror.
  </Step>
</Steps>

## Tips

* **Merge** creates a single printable object; without merge you get two separate pieces
* Enable **Flip UVs** if text or asymmetric patterns appear backwards on the mirrored half
