Which tool is primarily used for drawing shapes and paths in After Effects?

The primary tool used for drawing shapes and paths in After Effects is the Pen Tool. This tool allows users to create both open and closed paths with great precision, enabling the design of complex shapes and intricate vector graphics. The Pen Tool works by placing anchor points, which can be manipulated to form curves or straight lines, making it essential for custom shape creation within the composition.

While the Shape Tool is also designed for drawing shapes, it is more about creating preset shapes like rectangles, ellipses, polygons, and stars rather than offering the flexibility of creating custom paths. The Text Tool is specifically for creating and editing text elements, not for drawing shapes. The Brush Tool is primarily used for painting and creating textures or effects rather than creating defined shape paths. Therefore, the Pen Tool is uniquely positioned as the most versatile and powerful tool for drawing paths within After Effects, emphasizing its role in creating detailed and customized vector graphics.
