How To Use The Normal Attribute For Geometry Nodes

When working with geometry nodes, we also have the ability to work with the various attributes associated with our geometry that can be used to influence our node setups. The normal attribute defines the direction of our face domain, allowing us to control other nodes such as the extrude mesh node to determine which of our faces are going to be extruded. The normal attribute can also be used in other scenarios as well to control the selection and direction of our influenced geometry. In order to successfully use our normal attribute, we first need to be able to identify where the normal attribute is located in blender, what type of data it is, and the various ways in which it can be used for our geometry node system.
