There is an additional component “Smart Connectors”. Smart Connectors provide advanced object-avoiding orthogonal and polyline connector routing. This component available as in-app purchase both for Mac App Store and non App Store version of the app. See menu Store inside the app.
New items in the connector menu will appear after purchase this option.
There are orthogonal and polyline modes.
Routes are builded automatically but you can put checkpoints that connector must visit.
