# SurfaceBroker class

Namespace: [Grasshopper2.Parameters.Standard](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.parameters.standard.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
public static class SurfaceBroker
```

Represents one of several standard surface-like data types. Components which operate on or yield surface data of various kinds can use this type to avoid unnecessary casting in input or output parameters.

## Methods

- [Cast](https://developer.rhino3d.com/api/gh2/type/grasshopper2.parameters.standard.surfacebroker/cast.md): (static) Cast an object to the correct surface type.
