Chapter 7 Designing Pipe Runs

Overview of Designing Pipe Runs

Autodesk Civil Design has a Pipes menu that you can use to design

and draft pipe runs in your drawing that represent either storm water

or sanitary sewer collection systems.

You can start by drawing conceptual pipe runs, represented by single

lines, or you can import predefined pipe runs into the drawing. You

can use terrain models in order to obtain elevational data for the pipe

runs and you can associate a pipe run with a roadway alignment for

horizontal location data. After you have sized and configured the pipe

run, you can draft finished plan and profile pipe runs with a complete

feature set of customized labels, node structures, and graphical pipe

designations.

You can use the Pipes commands to:

■

Design and draft sanitary and storm water sewer systems in both

plan and profile views.

■

Perform flow, velocity, depth, slope, and other types of analyses to

satisfy a variety of design conditions using the Pipes Run Editor.

■

Determine hydraulic and energy grade line elevations for your

system.

■

Size the pipe segments and adjust run variables with the Pipes Run

Editor.

Some terms that are referred to in this chapter are described below.

Node: A node is the intersection of individual pipes, or the end of one

individual pipe, in a defined pipe run. In a sanitary sewer design, the

node is typically represented by a structure such as a manhole.

Pipe: A pipe is the entity that connects two unique nodes.

Run: A pipe run is a collective group of pipes and nodes. A pipe run

has a minimum of two nodes connected by a pipe.

Structure: A structure is the physical definition of the node such as a

catch basin, manhole, or an item at the end of a pipe.
