Connecting drainage system objects

Step-by-step:

Once you have placed predefined storm drainage system objects, such as manholes, into your surface model, you can connect them using the Connections tools in the Toolbox.

1. In the Toolbox, expand the Connections node.
2. Click Pipe.
3. Drag the pipe object to the model, place the symbol over the first Manhole, and click to place the start of the pipe.

• IMPORTANT: It is important that connections are digitized from upstream to downstream, following the normal direction of flow.
• 

4. Drag your cursor toward the second manhole. As soon as your cursor is over the next manhole, it changes to the crosshair arrows again.
5. Click to place the pipe end.
   
6. Click Manhole (1) again to place the start of the next pipe.
7. Drag toward and click Manhole (2) to place the end.
8. Continue to place the start and end points of each length of pipe, from manhole to manhole, until you have connected all the manholes.
9. In the Toolbox, click Select to stop the pipe creation mode.
