Axis is a line that is used to define a reference direction in a model or assembly.
Plane is a 2D surface that is used to define a reference plane in a model or assembly.
Axes and planes are essential features in SolidWorks, as they provide the necessary references for creating sketches, features, and assemblies.

Both axes and planes can also be created automatically as part of creating other features in SolidWorks, such as sketches and assemblies. For example, when creating a new sketch, SolidWorks automatically creates a default set of axes and planes that are used as references for sketching.
In summary, axes and planes in SolidWorks are important reference features that are used to define the orientation and position of other features in a model or assembly. They can be created manually using the Axis and Plane tools, or automatically as part of creating other features in SolidWorks.
