# Getting Started

> Open your first scene in Scene Editor, look around, and save your work.

## Before You Begin

You need:

* An Altoura account that belongs to the organization that owns the scene
* Permission to edit scenes in that organization
* A current desktop browser with hardware 3D graphics enabled, such as Chrome or Edge
* A mouse or trackpad. Many viewport actions use right-click and the scroll wheel.

Scene Editor always opens in a new browser tab. Allow pop-ups from the Altoura Dashboard if the tab does not appear.

## Open a Scene

1. Sign in to the Altoura **Dashboard**.
2. Open the **Scene Editor** page.
3. Click **Open** on an existing scene, or use **Create Scene** to make a new one.
4. A new tab opens with Scene Editor. If you are asked to sign in again, complete the sign-in and you are returned to the scene.

While the scene loads you see a loading dialog with the scene name, a progress bar, and an asset counter such as `3 / 12 assets`. You cannot edit until loading completes.

## Your First Look

When loading finishes you see:

* The **header** at the top with the scene name, your organization, the save status icon, and your profile picture
* The **ribbon** below the header with the editing tools
* The **Hierarchy** panel on the left listing every object in the scene
* The **3D viewport** in the center
* A grey figure marking the **Initial User Position**, which is where a trainee starts

Try these first steps:

1. **Look around.** Drag with the left mouse button in the viewport to orbit. Scroll to zoom. Drag with the right mouse button to pan.
2. **Select an object.** Click an object in the viewport or click its name in the Hierarchy. A cyan outline appears and a movement gizmo attaches to it.
3. **Move it.** Drag one of the gizmo arrows. Press **R** to switch to rotation, **T** for scale, and **G** to return to move.
4. **Frame it.** Press **F** to zoom the camera to the selected object.
5. **Undo.** Press **Ctrl+Z** (Windows) or **Cmd+Z** (Mac), or use the **Undo** button at the left of the ribbon.

## Add an Object

1. In the ribbon, click **3D Objects**.
2. Type in the **Search...** field or filter by tag.
3. Click an object to select it, then click **Insert**. Double-clicking an object also inserts it.
4. The object appears at the center of the scene and is selected. Drag it into place.

## Save Your Work

Scene Editor saves automatically a few seconds after each change when **Auto Save On** is shown in the ribbon's **File** group. You can also save at any time:

* Click **Save** in the ribbon, or
* Press **Ctrl+S** (Windows) or **Cmd+S** (Mac)

The cloud icon in the header shows the save state. A green check means everything is saved. A spinner means saving is in progress. A red mark means there are unsaved changes or the last save failed.

## Leave the Editor

Close the browser tab when the save icon shows a green check. If you close the tab with unsaved changes, the browser asks you to confirm before leaving.
