You can label the crossing pipe locations in profile views and section views.
Labeling crossing pipe locations may result in having two labels on a pipe (one regular pipe label and one crossing pipe label). If this is not desirable, you can use the Null label styles that are provided in the AutoCAD Civil 3D templates. Null label styles are set as the default styles for crossing pipe labels.
If the crossing pipe is moved to a different station along the alignment, the labels will be updated with the new station and elevation information.
If the crossing pipe is moved to a different elevation, the labels will be updated with the new information.
