Connecting a Junction to Blocks
Once a junction is inserted in a block diagram, you must connect it to the appropriate blocks to indicate the redundant configuration.
1. Click the connection point coming out of the block that is to connect to the junction and hold down the left mouse button while you drag the mouse until the mouse cursor is over the connection point going into the junction. A connector appears as you drag the mouse.
2. Once you are correctly positioned over the connection point going into the junction, release the left mouse button to insert the connector. If you are not correctly positioned when the left mouse button is released, a connector is not inserted.

If the connection points for a junction are not shown, you can press and hold down Alt while moving the mouse to drag the connector from the junction to another location.
