Start with the finished model from Lesson1.

add Drop-off Spurs

1. Using the Straight Path tool from the Library, create two straight spur paths near the Sink object.
   
2. Using the Join Paths tool, make a click-drag connection from the horizontal path that goes past the Sink to each of the spur paths.
   
   
   
   
3. Shift-Select all four spur paths (2 straight and 2 curved).
4. Click on one of the straight spur paths, and in the Quick Properties Straight Path panel on the right, check the "Two Way" box. Then press the "Apply To All Selected" popup button.
   
   This will make the spur paths two-way, so that AGVs can both enter and exit the spurs. You can see that the paths are two way by their arrow indicators. They look kind of like a diamond shape, with the ends pointing in opposite directions.
   
5. add a Control Point at the center of each spur.
   
6. Shift-Select the two new Control Points. It's OK if you also select the Paths.
7. A-Connect from the Control Point on the main loop to one of the spur Control Points, and choose DropoffPoints from the drop-down.
   
8. Shift-Click in a blank area to deselect the Control Points.

   • Trigger Requirement = Loaded at Destination
5. Beside the Way Point Logic field, press the button and choose Redirect via Search.
   A popup should appear as follows:
   
6. Leave all parameters as they are. These will be discussed later.
7. Close the popup by clicking off of it.

10. Click on the object named North in the list.
    
11. Press Select.
12. Press OK to close the AGV Network Properties window.
