Creating and Deleting Relationships

Having reviewed existing relationships on the Relationship Matrix, you can use the Matrix to quickly modify or delete those relationships and create others between the elements. This is a very useful facility for maintaining a large number of relationships in a short space of time. As you can filter for specific types of connector and source and target element, you can create a logical set of relationships without having to specify the type of each object every time.
