Indicate parent object


The Parent property indicates the parent object for a SimBiology® object (read-only). The Parent property indicates accessibility of the object. The object is accessible to the Parent object and other objects within the Parent object. The value of Parent depends on the type of object and how it was created. All models always have the SimBiology root as the Parent.
