# Activate Pattern Grading

## Assign a Size Chart to a Pattern Project

1. Open the project and make sure a pattern type is selected.
2. Click on **Assign/Manage Size Chart** button on the top bar or in the **Preview Sidebar** to open the **Size Charts** window.
3. Select the desired **Size Chart Template**.
4. Click on Assign button to confirm.

## Unassign Size Chart Template

1. Click on **Manage Size Chart** button on the top bar or in the **Preview Sidebar** to open the **Size Charts** window.
2. Click **Unassign** button in the Size Chart window to unassign the Size Chart Template

## Unassigning a Local Size Chart

When you unassign a Local (pattern-specific) Size Chart, the chart is permanently deleted.

**Local Size Charts** exist only within the context of the pattern they are assigned to.

For this reason, unassigning a local chart will remove it entirely and cannot be undone.

Before confirming the action, make sure that:

* The Size Chart is not needed anymore for this pattern
* Any required grading rules have been saved elsewhere (for example, as a template)

{% hint style="info" %}
If you want to keep the Size Chart for future use, consider [saving it as a Size Chart Template](/size-grading/manage-size-charts.md#save-a-local-size-chart-as-a-template) before unassigning it.
{% endhint %}
