Scale lets you resize your model before repair. Set a target dimension, multiply by a factor, or keep the original size.

## When to use this

When your model needs to be a specific size for printing — for example, a figurine that should be exactly 6 inches tall, or a mechanical part that must be 50 mm wide.

## Settings

### Scale mode

* **Target Scale** — Set the longest side to a specific size
* **Multiplier** — Scale by a factor (2x doubles, 0.5x halves)
* **Don't Scale** — Keep original dimensions

### Target value

The desired size when using Target Scale mode.

### Unit

Choose between millimeters (mm), centimeters (cm), or inches.
