Creating a Sanitary Sewer Network
In Chapter 14, you prepared a parts list for a typical sanitary sewer network. This chapter will lead
you through several methods for using that parts list to design, edit, and annotate a pipe network.
There are several ways to create pipe networks. You can do so using the Civil 3D pipe layout
tools. Limited tools are also available for creating pipe networks from certain AutoCAD and Civil
3D objects, such as lines, polylines, alignments, and feature lines.
Creating a Pipe Network with Layout Tools
Creating a pipe network with layout tools is much like creating other Civil 3D objects, such as
alignments. After naming and establishing the parameters for your pipe network, you’re pre-
sented with a special toolbar that you can use to lay out pipes and structures in plan, which will
also drive a vertical design.
Establishing Pipe Network Parameters
This section will give you an overview of establishing pipe network parameters. Use this section
as a reference for the exercises in this chapter. When you’re ready to create a pipe network, select
Pipe Network Pipe Network Creation Tools from the Create Design panel on the Home tab. The
Create Pipe Network dialog appears (see Figure 15.2), and you can establish your settings.
Figure 15.2
Before you can create a pipe network, you must give your network a name; but more important,
you need to assign a parts list for your network. As you saw in Chapter 14, the parts list provides a
toolkit of pipes, structures, rules, and styles to automate the pipe-network design process. It’s also
important to select a reference surface in this interface. This surface will be used for rim elevations
and rule application.
When creating a pipe network, you’re prompted for the following options:
Network Name Choose a name for your network that is meaningful and that will help you
identify it in Prospector and other locations.
Network Description The description of your pipe network is optional. You might make a
note of the date, the type of network, and any special characteristics.
Network Parts List Choose the parts list that contains the parts, rules, and styles you want to
use for this design (see Chapter 14).
Surface Name Choose the surface that will provide a basis for applying cover rules as well
as provide an insertion elevation for your structures (in other words, rim elevations). You can
change this surface later or for individual structures. For proposed pipe networks, this surface
is usually a finished ground surface.
Alignment Name Choose an alignment that will provide station and offset information for
your structures in Prospector as well as any labels that call for alignment stations and/or offset
information. Because most pipe networks have several branches, it may not be meaningful for
every structure in your network to reference the same alignment. Therefore, you may find it
better to leave your Alignment option set to None in this dialog and set it for individual struc-
tures later using the layout tools or structure list in Prospector.
Using the Network Layout Creation Tools
After establishing your pipe network parameters in the Create Pipe Network dialog (shown pre-
viously in Figure 15.2), click OK; the Network Layout Tools toolbar appears (see Figure 15.3). No
other command can be executed while the toolbar is active.

The Network Layout
Tools toolbar
Clicking the Pipe Network Properties tool displays the Pipe Network Properties dialog, which
contains the settings for the entire network. If you mistyped any of the parameters in the original
Create Pipe Network dialog, you can change them here. In addition, you can set the default label
styles for the pipes and structures in this pipe network.
The Pipe Network Properties dialog contains the following tabs:
Information On this tab, you can rename your network, provide a description, and choose
whether you’d like to see network-specific tooltips.
Layout Settings Here you can change the default label styles, parts list, reference surface and
alignment, master object layers for plan pipes and structures, as well as name templates for
your pipes and structures (see Figure 15.4).
Profile On this tab, you can change the default label styles and master object layers for profile
pipes and structures (see Figure 15.5).
Section Here you can change the master object layers for network parts in a section (see
Figure 15.6).
