Some common uses of the Null node:

• If you point a path reference to a node in the middle of a network, you may later need to add more nodes below the referenced node to further process the geometry, and then you would have to update all the references to the original node to point to the new node that now outputs the “finished” geometry. Instead, it is good practice to insert a Null SOP below the node whose output geometry you want to grab, and then reference the Null SOP. That way you can add more nodes above the Null without having to change any references to the Null.

• You can crate spare parameters on a Null and channel reference them from elsewhere in the network as a simple way to add some parameters to control things in the network.
