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.

Example: Clicking the shoulder line activates the HALF SHOULDER WIDTH STRAIGHT input field.

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 calculates related measurements from the entered values using its internal calculation rules.

Note: Clab keeps your manually entered measurements and recalculates related values based on your inputs.

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

• 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.

Two-piece jacket sleeves

For supported men's, women's, boys', and girls' two-piece jacket sleeve patterns, use the available measurements to refine:

• The inner seam position at the upper arm, elbow, and hem, and the division between upper sleeve and undersleeve at the sleeve cap.

• Undersleeve width at the elbow and hem, within the specified elbow circumference and sleeve opening.

• Elbow rotation and hem dart intake.

The fields shown depend on the selected Pattern Type.
