What is the purpose of the Mirror feature in SolidWorks?

The Mirror feature in SolidWorks is used to reflect parts, features, or sketches symmetrically across a specified plane. This functionality is particularly valuable in 3D modeling as it allows designers to create symmetric components efficiently, reducing the need to model each side separately. By reflecting geometry across a defined mirror plane, users can ensure that both sides of the model maintain perfect symmetry and are automatically updated if changes are made to the original feature. This streamlines the design process and enhances productivity, especially in cases where objects have bilateral symmetry, such as in automotive parts, machine components, and architectural elements.
