## Methods

- [Add](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.gh-wiretopologydiagram/add.md): Add a new wire is it isn't part of the diagram already.
- [AppendDiagram](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.gh-wiretopologydiagram/appenddiagram.md): (3 overloads) Create a wire topology diagram which describes the entire document.
- [DestroyConnections](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.gh-wiretopologydiagram/destroyconnections.md): Destroys the topological connector wire if it exists.
- [EnsureConnections](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.gh-wiretopologydiagram/ensureconnections.md): Creates the topological connector wire if it doesn't already exist.
