## Overview
This tool is designed for situations where curve lengths vary, enabling optimization of CV counts based on distance.
1. Select ‘curves’, not group. Make sure only ‘curves’ are selected.
2. Simply drag the slider or key in a distance. (Distance is based on 'cm').
3. Once happy with the result, make sure to click on Rebuild to confirm the rebuild.
* **Rebuild On Originals**
* Check **on** if you would like the rebuild to apply on original curves, or **off**, to create a new set of curves.
{% hint style="warning" %}
The Rebuild button must be clicked in order to move onto the the next batch of curves at the moment. If you accidentally mis-selected curves, either click on the Rebuild Button (without Rebuild On Originals), delete the new new group, or simply close the UI and reopen it.
{% endhint %}
