Exercise 3: Adding a Branch to a Pipe Network

In this exercise, you will add a branch to the existing pipe network layout and use the part status to review and edit the layout.

In addition to indicator icons that indicate where parts can be connected, you will see icons when the pipe or structure you are adding to the layout will break an existing pipe. The pipes created by the break are automatically connected to the new structure or pipe.

This exercise continues from Exercise 2: Changing the Surface, Alignment and Rules Configuration.

Add a headwall structure to the pipe network

Note:

This exercise uses Pipe Networks-2B.dwg with the modifications you made in the previous exercise.

1. If the Network Layout Tools toolbar is not already open, select a pipe network part. Right-click. Click Edit Network.
2. On the Network Layout Tools toolbar, ensure that the surface EG and the alignment XC_STORM are selected.

   For more information, see Exercise 2: Changing the Surface, Alignment and Rules Configuration.

3. In the Structures list, expand the Concrete Rectangular Headwall collection. Select 44 x 6 x 37 Inch Concrete Rectangular Headwall.
4. Click Structures Only.
5. In the drawing window, zoom to station 4+00 on XC_STORM.
6. Click near the alignment to place the headwall structure.

Connect the headwall structure to the pipe network

1. On the Network Layout Tools toolbar, click Pipes Only.
2. In the Pipes list, expand the Concrete Pipe collection. Select 24 Inch Concrete Pipe.
3. Toggle the Upslope/Downslope button to Upslope.
4. Hover the cursor over the rectangular headwall structure. With the connection marker displayed, click to connect the pipe.
5. Pan to the structure that is offset -15 feet from station 8+00 on ROAD1.
6. Hover the cursor over the structure. With the connection marker displayed, click the structure to connect the pipe.
7. Press Enter to end the command.

Rotate the headwall structure

1. Pan to the headwall at the end of the branch. Click the headwall to select it.
2. Use the circular editing grip to rotate the headwall until it is perpendicular to the attached pipe.
3. Press Esc to deselect the headwall.

Validate that design rules have been met

1. In Toolspace, on the Prospector tab, expand Pipe NetworksNetworksNetwork - (1). Click Pipes.
2. In the item view, in the row for Pipe - (10), place your cursor over the circular icon in the Status cell to view the design rules that have not been met.

   The pipe exceeds the maximum length and maximum cover found in the rules. In the next few steps, you will correct the length by adding a structure to the middle of the pipe span.

3. Right-click the row for Pipe - (10). Click Zoom To.

   The full extents of the pipe are displayed in the drawing window.

Insert a structure in the middle of a pipe

1. On the Network Layout Tools toolbar, in the Structures list, select Eccentric Cylindrical StructureEccentric Structure 48 Dia 18 Frame 24 Cone 5 Wall 6 Floor.
2. Click Structures Only.
3. In the drawing window, pan to station 2+00 on alignment XC_STORM.
   Note:

   You must turn off OSNAP to complete the following steps.

4. Place your cursor over a location on the pipe that is close to station 2+00.

   A break pipe marker is displayed to indicate that the pipe will be severed by placing the structure there.

   
5. With the break pipe marker displayed, click to place the manhole at the location, and create two pipes from the one.
6. Press Enter to end the command.
