In a design file, which action does the 'Align' tool primarily perform?

The 'Align' tool is primarily used to change the position of objects within a design file by aligning them relative to one another or to a specified reference point. This functionality is essential for creating precise layouts and ensuring that different elements within a design are organized in a visually cohesive manner.

When utilizing the 'Align' tool, designers can ensure that objects are positioned evenly, either horizontally or vertically, and can distribute them evenly across a space. This tool is often critical for maintaining symmetry and consistency in design, which is vital in professional applications where aesthetics and organization are paramount.

The other actions mentioned do not align with the primary function of the 'Align' tool. For instance, rotating components or scaling shapes involves different tools and commands that specifically address those operations, while grouping elements focuses on combining objects as a collective unit rather than positioning them relative to each other.
