The object manipulator enables you to change an object's alignment or orientation (ie, to modify its local coordinate system). You can either align each axis manually or use one or more markers or axes to help align your local coordinate system.

For either method, make sure you first pause the live stream.

### Align objects manually

With the object manipulator enabled and an object selected, you can either:

- Rotate an axis directly in the 3D workspace; or
- Enter a value in the rotation fields for each axis. You can also specify whether you want this to be a local or global rotation using the reference frame buttons > Macro (inline-media-image)

 (see [Change an object's origin](https://vicon-help.atlassian.net/wiki/spaces/Tracker44/pages/376309079)).
  If the global reference frame is selected, each axis identifier within Rotation changes to an active state (eg, > Macro (inline-media-image)

). Selecting one of these axes aligns it to its corresponding global axis.

> ⚠️ **Note**  
> ⚠️ The object's alignment depends upon the axis that you select:
> ⚠️ 
> ⚠️ > Macro (inline-media-image)
> ⚠️ 
> ⚠️  Rotates the object -90 degrees about the global coordinate system's Y-axis
> ⚠️ 
> ⚠️ > Macro (inline-media-image)
> ⚠️ 
> ⚠️  Rotates the object +90 degrees about the global coordinate system's X-axis
> ⚠️ 
> ⚠️ > Macro (inline-media-image)
> ⚠️ 
> ⚠️  Aligns the object to the global coordinate system

> Macro (scroll-pagebreak)

### Align with marker or axis

To align an object with a marker or axis:

1. Ensure the object manipulator is enabled and the required object is selected.
2. Click the alignment tool (for more information, see [Understand the alignment tool](https://vicon-help.atlassian.net/wiki/spaces/Tracker44/pages/376309145)).
3. Set your primary axis. To do this:
  - In the **Primary Axis** line, select the target type (**Axis**, **Marker** or **Center**), followed by the target.
    - If you chose **Axis**, you choose the target from a drop-down menu.
    - If you chose **Marker** or **Center**, you are prompted to select one or more markers.
  - Select the axis (X, Y or Z) and its direction (+/-)
4. Repeat step 3 for the **Secondary Axis**.  
Note that if the Axis or Target in the Secondary Axis is the same as Primary Axis, the **Align** button is unavailable.
5. Click **Align**.
  :check_mark: **Tip**: With the system still paused, you can undo (CTRL+Z) or redo (CTRL+Y) the most recent alignment.

After you have aligned your object, you can then update the object details or export as a .*vsk *file. For more information on changing your object’s details, see [Manage objects](https://vicon-help.atlassian.net/wiki/spaces/Tracker44/pages/376309124).
