# GH_TypeLib module

Namespace: [Grasshopper.Kernel](https://developer.rhino3d.com/api/gh1/namespace/grasshopper.kernel.md) · Assembly: [Grasshopper](https://developer.rhino3d.com/api/gh1/assembly/grasshopper.md)

```cs
public module GH_TypeLib
```

Utility module that caches a number of oft-used types and type-ids for quick access. Do not change any of the values in this module or you'll wreck casting and conversion logic.
