Use the waypoint shape to join two or more connectors together.

1. Drag the waypoint shape from the Misc shape library.
   
2. Drop the waypoint shape on a blank area of the drawing canvas, or hover over an existing connector until it is highlighted, then drop the waypoint shape.
3. Drag connectors to and from the waypoint shape to join them.
   

See examples of waypoint shapes in various types of diagrams

Tip: If you don’t see the Misc shape library, click on More Shapes, enable the General shape library, and click Apply.
