A UI Panel or UI Group Box to which a NestedUIConfig stereotype is applied and a feature tag set can represent some parts and nest other components. One of the samples that shows such purpose is the test_nested_UI_panels.mdzip sample, which is located in the samples/simulation/tests folder of the MagicDraw installed directory. 

The following System Class diagram shows the structures of Class system and Class monitor

On the same Class diagram, there are Instance Specifications of Class wystem and Class monitor that will be used in the simulation as follows
