Create pressure networks in Civil 3D

00:03

Pressure pipe networks are used for main water transmission systems.

00:08

In this example, you use Civil 3D to create a pressure network by selecting a reference surface to assign elevations.

00:16

This is an effective way to convert a rough sketch of a pressure pipe design into a 3D pressure network model.

00:23

From the Home tab, in the Create Design panel, click Pipe Network and select Pressure Network Creation Tools.

00:32

In the Create Pressure Pipe Network dialog, add the following information for this example:

00:38

Network name: CULINARY

00:42

Pipe Run name: Pipe Run

00:45

Parts list: Standard

00:49

Pipe size: Pipe-8 in-push on-ductile iron-350 psi-AWW

00:56

Reference surface: VO-SM

01:00

Enable Create surface profile to follow, and add a Cover distance of 3.000'.

01:07

Reference alignment: LONG CT

01:10

Pressure Pipe label style: <none>

01:14

Fitting label style: <none>

01:17

Appurtenance label style: <none>

01:21

Click OK.

01:24

Click to select the path in the drawing area for WATER MAIN 1.

01:29

Follow the path shown in cyan which is located on the _WATER layer.

01:34

When you get to a point on a curve, simply select CURVE from your command line.

01:40

To revert to a straight line, simply select STRAIGHT from the command line.

01:46

Once finished, press ENTER.

01:49

Adjust your curved pipe if needed by selecting the pipe and using the grips.

01:55

Continue your pipe layout by inserting an 8” TEE where the 2 roads intersect.

02:00

From the Ribbon, on the Layout panel, select an 8x8 inch tee and select ADD FITTING to insert the tee.

02:08

You can then continue to work with your pressure network layout.
