If what looks like text is text and not vectors then you have a few options. The elevate lines or create points from spot elevations commands is where I would start. You may want to review any of the videos or tutorials related to site modeling or data prep to see how these are used. Each one has multiple options and their use depends on what you have and what your goal is. On the support tab the Retreive command takes you to this website with multiple videos:

If you are estimating quantities or rough grading the corridor these may work for you. If you need a more accurate model then i would suggest creating the hal, val and making a proper template. These are not trivial the first time you use them, so you may want to consider training if you are not comfortable in these details. Your SITECH dealer should be your first contact if you need additional training.
