Drawing and Defining Pipe Runs

The first step in designing the pipe run is to lay out the conceptual

pipe run in your drawing. Conceptual pipe runs are single line

representations of plan and profile view pipe runs. They serve as quick

sketches of pipe run configurations, which you can use to check a

particular pipe run for proper layout and location.

Key Concepts

■

From the Pipes menu, choose Define Pipe Runs

➤

Draw Pipe Run

command to draw pipe runs by manually selecting starting and

ending points of individual pipe run segments, and specifying their

elevations. This command also defines the pipe run to the database.

■

From the Pipes menu, choose Define Pipe Runs

➤

Define By

Polyline to define the pipe run from an existing polyline in your

drawing.

■

You can also create a pipe run by importing a file that is saved as an

ASCII text file.

■

You can draw the pipe run by specifying stations and offsets from

an existing alignment.

■

You can draw pipe runs with or without referencing a terrain

model. A terrain model can provide you with surface elevations for

manhole rims, or you can input the manhole elevations manually.

■

When you save the pipe run, you can also define the pipe run as

an alignment, or you can select an existing alignment to associate

the pipe run with. By associating the pipe run with an alignment

or by defining it as an alignment, you can draft the pipe run in

profile view.

■

You can edit various pipe run parameters in the Edit Run Node

dialog box, which you can display from the Pipes menu, by

choosing Conceptual Plan

➤

Edit Graphical.
