# Drawing Line Art

Lines (also called “line art”) are the basis for all shapes that you draw with Toon Boom Studio vector drawing tools. As lines are the basis of all shapes, points are the basis of all lines.

Points can run down the center of a line, creating what is called a centerline. Or, points can run around the outside of a shape, creating a line called a contour.

- The Line , Polyline , Pencil , Rectangle and Ellipse tools create centerline shapes of a set width.
- The Brush tool creates variable-width strokes that respond to the pressure you apply with a digital pen and graphic tablet. The points that compose a brush stroke surround a zone that is filled with color, creating a contour.

The tool you select depends on the type of effect you want to create as well as considerations for the file size of your final animation.

| When you draw your characters, you may want to wait to draw the lip positions until after you import the sound track. Toon Boom Studio features a powerful lip-sync generator. With this tool, you can generate a lip chart that identifies the animation phoneme that matches each frame. You can use the lip chart as a reference while you draw the lip positions of your characters. The features of Sceneplanning Tools may change how you approach drawing with Drawing Tools. With Sceneplanning Tools, you can create motion, scale and rotation changes over time. Therefore, you do not have to animate these changes in your drawing objects with Drawing Tools.
