A subsystem can be modeled, exported, and imported as one independent entity. The subsystem concept allows one to reutilize a set of entities which are contained in a subsystem. A system can have multiple levels of the subsystem.

•Subsystem page: Mother Body can be dispatched as other body by clicking Pt in the subsystem page.
•Origin and Orientation page: Parent maker of a child subsystem. The marker becomes the inertia marker of the child subsystem.
•Euler Angle: 321 or 313 Euler Angles
•Note: Euler Angle can be defined as Parametric Value. Parametric Value unit is radian, so, if the user wants to degree value, the user must add "D" character such as "90D" in the Parametric Value.
