# Pattern Versions

When a project is active, the **Options** menu gives you access to version control tools for managing pattern changes over time.

## Create a Pattern Version

Click **Create Version** to save a snapshot of the pattern's current state — including:

* Measurement values
* Pattern configuration
* All relevant settings

This is useful for keeping track of progress or testing variations without losing previous data.

## Access and manage pattern versions

The **Pattern Versions** panel allows you to:

* View all saved versions for the active project
* Restore a previous version at any time

## Size Reference comparison

You can set any version as the **Size Reference**.

When this is enabled, measurements from the reference version are shown alongside current values in the **Measurements List** (under *Measurements Settings*), allowing for easy comparison.

#### Example:

If your **Size Reference** is the finished version and you're working on a version with:

* X shrinkage: 3%
* Y shrinkage: 2%

…the two versions will be shown side by side in the list, making it easier to evaluate changes.

## Restore a version

To revert to a previous version:

1. Open the **Pattern Versions** list
2. Select the desired version
3. Click **Restore**

Clab Assistant will apply all data from the selected version to your current project.
