Drawing and Defining Pipe Runs
The first step in drawing and defining a pipe run is to use the Draw Pipe Run
command to locate the starting and ending points of individual pipe run
segments. You can draw pipe runs in two ways: by station and offset from a
defined horizontal alignment, or by manually selecting points.
You are prompted for a method for determining rim elevations. You can either
use elevations from a surface or you enter these elevations manually.
To draw and define pipe runs
1 From the Pipes menu, choose Define Pipe Runs ä Draw Pipe Run.
The following prompt is displayed:
Enter a new run name:
2 Type a new pipe run name with a maximum of 30 characters. If defined surface
files exist, then the Select Surface dialog box is displayed.
If no surface is being used, then the rim elevations must be entered manually.
You are prompted, one at a time, as the pipe run segments are drawn.
3 Continue with one of the following tasks:
n
Extract Rim elevations from a defined surface.

n
Manually input the rim elevations.
