# Transforming Content

## Moving, Scaling, and Rotating 3D Content

### Using Metadata

You can use metadata to **persistently** transform 3D content.

If the content is too big or too small or if you'd like to move or rotate it, go back to the console and [add metadata](https://docs.echo3d.com/web-console/manage-pages/data-page/how-to-add-data#adding-metadata) to affect its transformation. After adding or changing metadata you can instantly see the changes in the browser even **while the experience is running**.

The following keys are words the system uses as pre-defined metadata keys to control transformations:

<table data-header-hidden><thead><tr><th width="150">Keyword</th><th width="150">Type</th><th>Options</th><th>Effect</th></tr></thead><tbody><tr><td>Keyword</td><td>Type</td><td>Options</td><td>Effect</td></tr><tr><td>x</td><td>float</td><td><p>Any positive or negative number.</p><p>Default value is 0.</p></td><td>Moves the asset on the x-axis</td></tr><tr><td>y</td><td>float</td><td><p>Any positive or negative number.</p><p>Default value is 0.</p></td><td>Moves the asset on the y-axis</td></tr><tr><td>z</td><td>float</td><td><p>Any positive or negative number.</p><p>Default value is 0.</p></td><td>Moves the asset on the z-axis</td></tr><tr><td>scale</td><td>float</td><td><p>Any positive number.</p><p>Default value is 1.</p></td><td>Grows or shrinks the asset uniformly</td></tr><tr><td>height</td><td>integer</td><td>Any positive number.</td><td>Set the height of an image asset or a video asset</td></tr><tr><td>width</td><td>integer</td><td>Any positive number.</td><td>Set the width of an image asset or a video asset</td></tr><tr><td>xAngle</td><td>float</td><td><p>Any positive or negative number.</p><p>Default value is 0.</p></td><td>Rotates the model on the x-axis</td></tr><tr><td>yAngle</td><td>float</td><td><p>Any positive or negative number.</p><p>Default value is 0.</p></td><td>Rotates the model on the y-axis</td></tr><tr><td>zAngle</td><td>float</td><td><p>Any positive or negative number.</p><p>Default value is 0.</p></td><td>Rotates the model on the z-axis</td></tr></tbody></table>

Remember to refresh the browser after adding metadata with FaceAR experiences for the changes to take effect.&#x20;
