Manhattan Router

The Manhattan router ensures that connection segments are either vertical or horizontal at all times, not matter how you move individual bendpoints. This means that the angle at a connection's bendpoint will always be 90 degrees. Also the connection segment entering a node will always be orthogonal to the side of the node. The Manhattan router can only be used in class diagrams and only applies to relationships. It does not apply to the links from notes to classifiers or relationships. You can switch between the default fan router and the Manhattan router with the diagram's context menu, which appears when you right-click on the diagram's background.

When you switch between the Manhattan and the default fan router, all manually routed bendpoints will be removed as the connections revert to automatic routing.

Automatic routing with the Manhattan router is quite similar to the fan router. With manual routing there are substantial differences:
