# Measurements and Preview

Clab Assistant offers a dynamic way to manage and visualize pattern measurements.

## Interactive Pattern Preview

In the **Pattern Preview** panel, an example of the selected pattern is shown. Each piece displays the key measurement points required for pattern generation.

* When you **hover over a measurement input**, the corresponding line on the preview is highlighted.
* Conversely, **clicking a line** in the preview will automatically activate the input box for that specific measurement — with the cursor ready for input.

{% hint style="info" %}
**Example:** Clicking the shoulder line activates the **HALF SHOULDER WIDTH STRAIGHT** input field.
{% endhint %}

As you move the cursor from one piece to another, **dashed lines** appear to indicate:

* Entered measurements
* Remaining measurements still to be filled

## Entering Measurements

Manually enter measurements in the corresponding input fields.

* **User-entered values** are marked by a **light blue vertical bar** to the left of the input box.
* To better understand each measurement, you can click its **name** to open a **descriptive image**.

## Required Fields

To generate a pattern, **at least two key measurements** must be entered:

* **Chest Circumference**
* **Back Length**

Once these are provided, Clab Assistant automatically calculates all other related measurements using its internal algorithm.

{% hint style="info" %}
**Note:** Manually entered measurements will **not** be overridden by the algorithm. Related values will adjust around them.
{% endhint %}

## Real-time Updates

As you enter or edit values:

* The **Pattern Preview updates instantly**, giving you immediate feedback.
* This helps you validate how each change affects the overall design.

## Zoom and Navigation

* To zoom in on the preview, click the **zoom icon** in the top-left corner of the preview window.
* You can also use the **mouse wheel** to zoom in or out.

## Pattern Generation

Once all data has been entered:

1. Click **Generate Pattern**
2. A window will appear with options to **download** the pattern files in the desired format

## Additional Options

At the bottom of the **Measurements Settings** panel, you’ll find additional options to customize the pattern:

* Add/remove **darts**
* Switch between **one-piece** and **two-piece sleeves**
* Enable or disable **hood**, if available

These options allow you to configure the structural elements of the pattern before generation.
