We have just released a new add-on called MirrorPro. This add-on is designed to make it easy and quick to mirror objects using an interactive Gizmo.
Mirroring objects is one of the most commonly used steps in the modeling workflow.
With this add-on, you can eliminate the tedious process of adding mirror modifiers or symmetrizing the geometry.
Using its advanced features, you can mirror objects in all possible directions with just one click.
Additionally, there are more features available.
