# Modifying a Pen Style

You can modify the size, smoothness, and name of any pen style in the animation set. When you make changes to a pen style, Toon Boom Studio updates the pen styles in every scene in the animation set. Only drawings you make after the pen changes are affected.

To modify a pen style:

1. Select the pen style you want to modify.

2. Modify the characteristics of that pen style by adjusting the following:

- Select the minimum and maximum size of the drawing line with the Minimum size/Maximum size sliders.
- Adjust the smoothness of the line from the Smoothness slider.
- Rename the pen style by double-clicking it and typing the new name in the field.

| Any changes you make to pen styles only affect the lines you draw afterwards. If you remove a pen style, any lines you drew with that pen style do not change; the line art remains unchanged even if you delete the pen style that created it.
