### ExportToFile

*No description yet.*

```csharp
void ExportToFile(string argPath, TLayerStackDocumentFormat argFormat, int argImperialPrecision, int argMetricPrecision);
void ExportToFile(string argPath, int argFormat, int argImperialPrecision, int argMetricPrecision);
```

| Parameter | Type | Passing |
| --- | --- | --- |
| `argPath` | `string` | value |
| `argFormat` | [TLayerStackDocumentFormat](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/TLayerStackDocumentFormat.md) | value |
| `argImperialPrecision` | `int` | value |
| `argMetricPrecision` | `int` | value |

**Returns:** nothing (`void`)

The first overload is an extension method of `ILayerStackProviderHelper` (`using PCB;`) with typed parameters; the second is declared by the interface.

### ExportToString
