# Export Unity Prefab

> How to export Unity Prefab files from Asset Transformer Studio

![Export Unity Prefab](/api/media?file=/asset-transformer-studio/2026.5.0/media/STUDIO_ExportPrefab.gif)

In order to bridge the gap between the CAD world and Unity Editor to unlock [Real-Time 3D](https://unity.com/solutions/architecture-engineering-construction) content creation, Asset Transformer Studio natively supports the export of [Unity Prefab files](https://docs.unity3d.com/Manual/Prefabs.html).

In Unity, a Prefab is a special type of component that allows fully configured [GameObjects](https://docs.unity3d.com/Documentation/Manual/GameObjects.html) to be saved in the Project for reuse.

This export capability provides a streamlined workflow from CAD/3D models to Unity Editor:

> 1. [Import](../importing-files) and aggregate CAD/3D models in Asset Transformer Studio.
> 2. Prepare and optimize them using the full extent of Asset Transformer Studio features.
> 3. Export as a .prefab file, directly in the targeted Unity Editor project.

> **Note:**
>
> To import multiple 3D models optimized with Asset Transformer Studio **in a runtime app** built with Unity, the recommended solution is to use glTF files as pivot files, generated with Asset Transformer SDK: more information [here](https://unity.com/products/pixyz-sdk#introduction-to-workflows).
