## About this Block

**What it does:**  This block mirrors an existing FE Mesh to cut down processing time for symmetrical parts.

**Commons uses:**

* Topology Optimization
* Analysis

**Tips:**

* Start with a part that is already halved or cut it in half using a Plane with **Boolean Subtract**.
* You can merge the meshes after mirroring or keep them separate. If you keep them separate, you will need to use a Connector in your **FE Model**.
