The command "Mirror Feature" is specifically designed for duplicating and reflecting a feature about a specified mirror plane. This functionality allows users to create a new feature that is an exact mirrored version of the original, which is particularly useful in design tasks where symmetry is a key requirement. By using this command, designers can ensure that any modifications made to the original feature are automatically reflected in the mirrored feature, thereby maintaining design integrity and reducing the effort required to manage symmetric designs.

In contrast, the other choices serve different functions within the software. The "Symmetric Feature" is often used for defining relationships in sketches rather than mirroring existing features. The "Revolve Feature" involves creating a 3D shape by revolving a 2D profile around an axis, which does not apply to mirroring. The "Pattern Feature" is about creating copies of features in a specified arrangement rather than reflecting them, thus not suitable for the task of mirroring.
