Routing Tab

The Routing tab allows the user to change routing options between objects. The screenshot is shown for the Parallel router; not all groups or buttons are available for all routers.

Routing Group

1. Routing Group
The Routing gallery provides different methods of connecting objects. The Auto Route button enables the chosen router.

Routing Settings Group

Use Wall Optimization and Avoid Shapes options try to route the lines to avoid going over an object; however, it is not always possible to avoid all shapes. At times, you may have to manually move an object to see the routing adjust. The Router Inflation field sets the distance from the object to where the relationship can start to turn. An inflation of zero sets the first bend (or arrow) of the line at the object's border.
Use Connection Offset and Connection Offset are only available with the Parallel router; they set the distance between multiple lines connecting to the same object. The Max Iterations field sets the number of times the routing algorithm attempts to route between objects. Higher values tend to be slower, while lower values may not produce the most optimal routes. A good starting point is 200 iterations. The Grid Size field sets the size of the grid to route through. This field is especially useful with the Grid router, and is most easily seen by enabling Show Grid in the Settings tab of the Ribbon Bar.
If Gliding routing type is selected, the Routing Settings Group contains the Allow Parallel button to render separate parallel connectors when bi-directional connectors overlap.

Connector Options Group

3. Connector Options Group
The Routing Margin field sets the amount of invisible space around each object; the router tries to route outside of this space. The Bridge pull-down menu provides the option to add a Bow or Gap where lines overlap; however, this may cause diagrams with many connections to generate slowly. The Gap Radius field sets the width of the Gap bridge and the height of the Bow bridge.
The Connection pull-down menu lets you change the look of the connection: Polyline, Bezier, or Spline.
The Round Corners button tries to round out 90 degree corners on Polyline connections; this is helpful when lines overlap. The Align Labels button changes the orientation of the text labels to match the line orientation. Show Stereotypes adds the relationship type to the routing line.
