# Editing elements

> Adjust position, rotation, scale, and other properties of staged elements in Holos Learn.

Tap any element in the 3D stage to select it. The **Properties panel** opens on the right showing the element name and all available controls. Tap **×** to deselect.

## Actions

The top of the panel has an action bar with controls that apply to the selected element:

| Action              | Description                                                            |
| ------------------- | ---------------------------------------------------------------------- |
| **Lock / Unlock**   | Prevent or allow edits to the element                                  |
| **Delete**          | Remove the element from the stage permanently                          |
| **Duplicate**       | Create a copy of the element in place                                  |
| **Face**            | *(Media only)* Element automatically orients toward the viewer         |
| **Follow**          | *(Media only)* Element moves with the camera rather than staying fixed |
| **Group / Ungroup** | *(3D objects only)* Toggle grouping for hierarchical objects           |

When **Face** is on, rotation controls are disabled. When **Follow** is on, position controls are disabled.

## Move, Rotate, Scale

All element types support position, rotation, and scale adjustments via three-axis sliders. Changes apply in real time.

## Text

For text elements, the **Text** section lets you edit the content directly. Tap **Update** to apply.

The **Format** section controls:

* Font (Public Sans, Inter, JetBrains Mono)
* Weight, size
* Bold, italic, underline, strikethrough
* Horizontal and vertical alignment
* Text color

## Video controls

For video and recording elements:

| Control      | Description                                                        |
| ------------ | ------------------------------------------------------------------ |
| Play / Pause | Preview playback in the stage                                      |
| Loop         | Repeat the video continuously                                      |
| Start on     | **Stage Entry** plays automatically; **Tap** waits for the learner |
| Volume       | 0–100%                                                             |

## Highlight color

3D objects can have an optional highlight color applied as an overlay. Use the color picker to set it, or remove it to go back to the default appearance.

## Animation

If a 3D object has animations built into its source model, they appear in the **Animation** section. Tap an animation to activate it and toggle looping. Only one animation can be active at a time.
