# ExternalBuildDrawer

> Draws the report for builds made outside the Unity build pipeline, in the Build Analysis window.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.Build.Analysis](/engine/6000.7/script-reference/unityeditor/build/analysis.md)
* **Assembly:** UnityEditor.BuildAnalysisModule

```csharp
public abstract class ExternalBuildDrawer
```

## Remarks

Mark an implementation with [ExternalBuildDrawerAttribute](/engine/6000.7/script-reference/unityeditor/build/analysis/externalbuilddrawerattribute.md) to declare which package's builds it draws. The window gives the drawer its whole content area, so the drawer supplies its own tabs and toolbar.
