There is no requirement for classes to subclass any standard root class, so you can include or omit a superclass as needed.

Currently only 3D plugins are implemented within KiCad but it is envisioned that a PCB possible for users to implement data Importers and Exporters. ### 1.1 Plugin Classes Plugins are divided into Plugin Classes since each plugin addresses problems in a specific domain and therefore requires
