What are the special features of connections?

Different anchor points on objects are offered for selection depending on the connection type.

Depending on the method, the selection of anchor points for an object can be restricted, such as from the Entity type to the Generalization object types in models of the eERM type. While the is supertype of connection type can only be drawn from the entity type to the tip of the generalization type, the is subtype of connection type can only be attached to the bottom of the generalization type.

The method also specifies, whether one or more connections can be created between two objects. If you create a connection per anchor point between two objects and this is not allowed according to the method, a prohibitory sign will be displayed on the target object. If you draw a connection from a source to a target object which is only allowed by the method from the target to the source object, the permitted connection will be created. If several connection types are allowed between two objects, these are offered in a pop-up window.

If a grid is set, the number of connection anchor points and the alignment of connections is affected by the grid width. The greater the grid width you set, the fewer connection anchor points will be offered.

If you enabled the special grid mode, connections will be arranged with half the grid width.

If you use quick modeling or the mini toolbar to place objects, connections between two objects will be created without you having to explicitly draw them.
