The lines which associate the two objects in the diagram are called Connector Lines.
On Selecting the line, options for connector lines are shown on the toolbar.
Lines can be applied in two ways:
Direct Route – connects the objects using the shortest path.
Avoid Route – connects the objects avoiding the other objects in the diagram structure.
Lines are of three types are available to connect the objects:
Orthogonal Lines – Orthogonal Lines are when the line appears with right angles in order to connect the two objects when it cannot be drawn horizontally or vertically.
This line is available only under Direct Route and will be disabled for Avoid Route.

Orthogonal On |

Jump Lines – Jump Lines are when one connecting line passes over another, and it appears with an arc over it.
This button are used in conjunction with the orthogonal lines button. If an orthogonal line is off for a particular line then the jump line button is disabled.
Jump is a property of an individual line, so if the lines cross and neither have the jump property then they look like straight lines passing through one another. Jump lines will be seen if both lines have jump property.
Lock/Unlock Link Port – Link Ports can be Locked or Unlocked. To lock them, either press the button or move the connection point (port) of the line, around the shape. When you select a location to port the line to the shape, it will become locked. If you want the diagrammer to automatically reposition the port, select the line, and press the unlock button, to release the lock.
Locking the link ports helps to keep the specific connection point when the shapes are moved around the canvas.
Naming on Association Links
To show the flow between the shapes, Association Names can be placed on Association Links.
To place the name on the link,
Double-click on Link or Connector Line you wish to add on.
A property panel will be opened on the right-side of the screen.
Enter Name and then click on Save on the bottom of the screen.
The Association Name can be moved around the screen by Clicking and Dragging it to a new location.
How to Add Missing Associations?
Associations between the shapes can be automatically displayed if a new object is added to the existing diagram. This will render the associations between the existing objects and the newly added objects in the existing diagram.
You can also place associations between any two or multiple objects using the button on the toolbar called Add Missing Associations.
Associations can be applied in three ways:
Upon Single Selection – Select any single object shape in the diagram and then click on Add Missing Association button to display the associations related to the selected object shape and the other shapes in the diagram.
Upon Multi Selection – Selection of any two or more shapes will render the missing associations to the objects that are already defined between them
No Selection – This will render all possible associations between the shapes in the diagram.
