Annotating Pipe Networks in Plan view
For a pipe system to function properly, it must be installed with a considerable
amount of accuracy. And for this to take place, detailed information must be con-
veyed to the contractor installing the pipes and structures in the field. The most
common way to do this is to add text to your drawing. With stations and offsets, you
provide the horizontal location of each structure; and with slopes and elevations,
you dictate the depth of each pipe and the slope needed for water to flow through it
properly. These values are typically expressed to the nearest hundredth of a foot or
thousandth of a meter. It's amazing to think that a trench can be excavated and a
heavy concrete pipe laid in it with such accuracy, but it happens every day.
So far, you have worked with functions that create pipes and structures, edit
their design, and control their graphical appearance in the drawing. In the fol-
lowing sections, you'll learn how to annotate your design, which is arguably
even more important than the design itself. The lines and symbols provide a
useful picture of the design, but the stations, offsets, elevations, slopes, and so
on provided by your annotations are used to make precise measurements that
locate and orient each pipe and structure in the field.
Renaming Pipes and Structures
Many pipe network designs involve a large number of pipes and structures. For
this reason, it's good design practice to have a naming and/or numbering system
that helps you keep track of these many components. Before labeling pipes and
structures, you should spend some time renaming them according to the system
you'll use.
Exercise 16.3: Rename Pipes and Structures
◀
If you haven't already
done so, download
and install the files for
Chapter 16 according to
the instructions in the
Introduction.
In this exercise, you'll do some “bookkeeping” to rename the pipes and structures
in the Storm1 network according to a numerical sequence.
1.
Open the drawing named
Renaming Pipes and Structures.dwg
located in the
Chapter 16
class data folder.
2.
In the viewport on the left, click the inlet at station 5+50 (0+170) that
is on the east side of Jordan Court. Right-click, and select Properties.
3.
In the Properties window, change the name to
INLET- 01
. Press Esc
to clear the selection, and then click the inlet across the street from
INLET- 01.
4.
In the Properties window, change the name to
INLET- 02
. Press Esc
to clear the selection.
