What is the "Mirror" feature used for in SolidWorks?

The "Mirror" feature in SolidWorks is primarily used to create a symmetric copy of a feature across a defined plane. This function is particularly beneficial when designing parts that are reflective or symmetrical in nature, as it allows users to efficiently duplicate complex geometries without needing to manually recreate each element. When a feature is mirrored, it maintains the original's characteristics and relationships, enabling precise modeling while saving time.

This feature simplifies the design process, especially for components in assemblies where symmetry is critical, such as brackets, frames, or aerodynamics-focused parts. By selecting the appropriate mirror plane, users ensure that the mirrored feature accurately reflects the intended design, leading to consistent dimensions and properties that align with the rest of the model.
