# Align

## <img src="/files/vQ8aK3uoVyKliq0SKvrU" alt="" data-size="line"> Align <a href="#profiles" id="profiles"></a>

The Align command lines up the bounding boxes of objects and object grips.

* When SubD faces, edges, or vertices are selected (with Ctrl+Shift), the associated control points are aligned.

### **Steps**

1. Select the objects to align, and press Enter.
2. Specify an alignment option.
3. Pick a location, or press Enter to align based on the overall bounding box of all selected objects.

### Command-line options

**AlignTo**

* **CPlane:** Aligns objects using construction plane coordinates.
* **World:** Aligns objects using world coordinates.
