For a pipe system to function properly, it must be installed with a considerable amount of accuracy. For this to take place, detailed information must be conveyed 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 will provide the horizontal location of each structure, and with slopes and elevations, you will 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 even think that a trench can be excavated and a heavy concrete pipe laid within 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 following sections, you will 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 will be used to make precise measurements that locate and orient each pipe and structure in the field.
