In the Create Feature Lines dialog box, notice that you can assign a name
to the feature lines as they are created. Naming significant feature lines
can make it easier to assign targets when creating a corridor. For this
exercise, you will assign names after the feature lines have been created.
Following this workflow enables you to create many feature lines at the
same time, but name only the most significant feature lines.

The lines are converted to feature lines and added to Site 1. You will
assign elevation values to these feature lines later in this exercise. Next,
