# NavMeshBuildDebugFlags

> Bitmask used for operating with debug data from the NavMesh build process.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.AI](/engine/6000.5/script-reference/unityengine/ai.md)
* **Assembly:** UnityEngine.AIModule

```csharp
[Flags]
public enum NavMeshBuildDebugFlags
```

## Remarks

Used in two situations:

* within [\_debug](/engine/6000.5/script-reference/unityengine/ai/navmeshbuildsettings/debug.md) to specify which debug data to retain after the build process has completed, preserving the world position and orientation;

* as a parameter of [NavMeshEditorHelpers.DrawBuildDebug](/engine/6000.5/script-reference/unityeditor/ai/navmesheditorhelpers/drawbuilddebug.md) to control which of the available debug data types to display for a specified NavMesh.
