 # Nodes
 
-## Nodes Design Concept
-
-In order to build a component, the general process is to first use a "Mask Method" node to build the surface of the component based on its layers, and then connect to a "Assign Shader" node to add the material physical properties. Finally, if you need to cut the cross-section, then connect to a "Cut" node. The whole process is shown in the following diagram

-
-A typical example looks like this:

-
-The "Mask Method" node tends to be very computationally intensive, and if it consumes too much time, then you can bake it with a "Bake" node after it (but you need to save the Blender file first).

 ## Mask Methods
 
-This type of node is responsible for culling out the extent of the component that does not need to be rendered, forming the interface between the object and the object, or the surface of the object (i.e., the interface between the object and the air)
