When using the Mirror command, what can you select as the mirror line?

The Mirror command in NX allows users to create a symmetrical copy of selected geometry across a defined mirror line. A plane or a sketch line can serve as this mirror line, providing the necessary reference to facilitate the mirroring process.

When using a plane, users can select standard planes such as the XY, YZ, or ZX planes, or create custom planes to achieve the desired symmetry in their designs. Sketch lines can also be utilized as mirror lines, which is particularly useful when working within a 2D sketch environment, allowing for easy symmetry between elements.

Using a single point, solid bodies alone, or only sketches is not applicable for the Mirror command as these options do not function as valid mirror lines. A single point does not provide the required reference for mirroring, while limiting the selection to only solid bodies or sketches restricts the flexibility of the tool. The inclusion of both planes and sketch lines ensures a versatile application of the Mirror command in various design scenarios.
