Which tool can be used to create symmetric shapes in a design?

The choice of tool that best creates symmetric shapes in a design is the Symmetry Tool. This tool is specifically designed to allow users to create and manipulate geometry symmetrically about a defined line, plane, or axis. It enables quick adjustments and ensures that any modifications made to one side of the symmetrical shape are automatically mirrored on the other side, which enhances design efficiency and accuracy.

While the other options have their respective functions — the Centerline is primarily used for construction purposes to define the symmetry line, the Center Mark is a utility for indicating the center of circular features, and the Reflect Tool serves to duplicate elements across an imaginary line — none of these tools facilitate the creation of symmetric shapes as effectively and intuitively as the Symmetry Tool does. Using the right tool for the intended design function is crucial in streamlining the modeling process, and in this case, the Symmetry Tool stands out as the most appropriate choice.
