Mirror Copy provides a CAD-style workflow for duplicating and mirroring objects across the X, Y, or Z axes. It generates an interactive reference plane at the 3D cursor's location, allowing users to position and rotate the plane to determine the exact placement of the mirrored copy. The tool supports both single and multiple objects simultaneously, with options to retain the original meshes or use clipping to merge the results into a single object. It functions independently of Blender's native mirror modifier.
