In lane models, lines separate rows and columns. You can move the lines. This column/row structure makes the models easier to view.
In process chain diagrams (PCDs), for example, each object type has its own column, which makes complex models easier to read.
When objects are created, relationships will automatically be created between specific object types. These relationships are not generated as visible relationships (connections), but as invisible relationships. As the creation of objects implies that corresponding invisible relationships will be created between them automatically, these are called implicit relationships.
In PCDs, for example, a relationship between functions and organizational units placed in the same cell is automatically created.
The insertion of certain objects into certain columns or lines in some models is restricted for methodical reasons. The mouse pointer will take the shape of a prohibitory sign, when you try to place an object into a column or row that is not allowed by the method.
