### **Steps**

1. Start the command.
2. Select mesh faces or boundary edges to extrude.

   To extrude a whole mesh, select the mesh before starting the command.
3. Set command-line options.
4. Pick or enter the extrusion distance.

### Command-line options

**EdgeLoop:** Pick an edge on the boundary to select an edge loop.

**Basis**

* **WCS:** All faces or boundary edges extrude in the same direction based on world coordinates.
  * **Direction**
    * **Free:** The direction is picked freely.
    * **X/Y/Z:** The direction is fixed to the world X, Y, or Z axis.

* **UVN:** Each face or edge extrudes in the direction based on UVN coordinates.
* **Direction**
  * **Free:** The direction is picked freely.
