# Space basics

> Where you refine one model: the layout, the tabs, and how versions work

**Space** is the second app, reached from **Open in Space** on any finished card, the **Space** link in the header, or **Open in Space** inside the viewer. It opens one model at a time and puts every tool around it.

## The layout

* **Top bar**: the model's name (click to rename), a switcher to jump to another of your models, the **?** controls sheet, **Export to Blender**, and **Download** with GLB, USDZ, OBJ and STL.
* **Tool tabs**: **Texture**, **Topology** and **Viewer**. Each tab shows its tools as tiles on the left; a tile opens its panel.
* **View strip**, top right: **Rendered**, **Clay**, **Wireframe**, **Color only**, **Surface bumps**, **Shininess**, **Metal**. Keys **1** to **7** do the same.
* **Gizmo**: click an axis to look from the front, back, top, bottom, left or right.
* **Layers**, at the bottom of any panel: every version of this model, with **In view** marking the one you are looking at.

## Versions

Every tool that changes the model saves a **new version** and keeps your **Original**. Retopology adds a clean-quad layer. A texture repair adds a patch layer and, when you save, a new version. Switch between them in the Layers list, and download whichever one is in view.

## The tools

| Tab      | Tool          | What it does                                                   | Cost      |
| -------- | ------------- | -------------------------------------------------------------- | --------- |
| Texture  | **Repair**    | Paint over a fault and redo only that spot                     | 1 credit  |
| Texture  | **Edit**      | Paint an area and describe what should change there            | 1 credit  |
| Topology | **Retopo**    | Rebuild the mesh as clean quads for games, rigging and editing | 2 credits |
| Viewer   | **View mode** | Clay, wireframe, or one texture channel                        | Free      |
| Viewer   | **Light**     | Studio presets and fine-tuning for a clean screenshot          | Free      |

<Tip>First time in? A hint under the model says: **Drag to orbit · Right-drag to pan · Scroll to zoom · ? for more**. It fades after your first move.</Tip>
