Which tool is utilized to edit vector lines in storyboard software?

The Contour Editor Tool is specifically designed for editing vector lines in storyboard software. This tool allows users to manipulate the curvature and shape of vector paths with precision. By adjusting points and handles along the vector lines, artists can refine their designs, ensuring the lines conform to their creative vision. It provides a level of control that is essential when working with vector graphics, as it enables fine-tuning of the shapes and outlines, creating smoother transitions and more intricate details.

In contrast, the other tools mentioned serve different purposes. The Pencil Tool is primarily for freehand drawing, allowing quick sketching without the same level of control over individual line attributes. The Shape Tool is used for creating predefined geometric shapes rather than editing existing vector lines. The Brush Tool simulates traditional brush strokes, focusing on texture and painting rather than vector line manipulation. Each of these tools has its unique functionality, but when it comes to editing vector lines specifically, the Contour Editor Tool is the most effective choice.
