Graphic object
Shapes that exist without reference to modeling methods.
Whereas an activity is used within the modeling method in the sense of Edit, Run, and Perform, graphic objects do not have semantics. This means that these shapes cannot be evaluated by the program.
However, you may find them useful in models. If you assign a graphic object to a model name, for example, this distinguishes it easily from object attributes. You can also use graphic objects to structure modeling areas. For example, by assigning graphic objects with the same color scheme to certain areas, you can show the relationship between certain modeling areas.
