If you use Del to delete a that is connected to two structurally relevant objects, Smart Modeling automatically creates a connection between the remaining objects. If you use Shift + Del, Smart Modeling does not create a connection between the remaining objects.
Basic model objects.
These are objects that indicate the distinctive feature of a model. For a model of the Organizational chart type, the objects Organizational unit, Role, and Person are structurally relevant objects, for example. Using these items, you can build the typical hierarchy of an organizational chart.
The Event and Function objects are typical for the EPC model type and are thus structurally relevant to a business process. You can use these to establish a typical control flow. The Organizational unit, Role, and Person objects can also be inserted into an EPC. However, these objects do not constitute the distinctive feature of a business process. As structurally irrelevant objects, they act as satellites and add more detailed information to the process model. For example, you can insert organizational units and link them to functions to illustrate who carries out those functions.
An object that can be inserted in a model or diagram but is not a structurally relevant object is known as a satellite.
Procedure
Open a model.
Select the object you want to delete.
If you want the connection between the remaining objects to be created automatically, press Del.
The connection is created.
If you do not want the remaining objects to be connected, press Shift + Del.
No connection is created.
You have deleted a structurally relevant object so that a connection is automatically created between the remaining objects or no connection is created.
