I created a property line and then added the toposurface points of various elevations in the site plan. When I go to the 3D view of the site, the topography is completely flat with only the topography lines showing up. Even when I render the view, my site appears completely flat. (see attached pictures) I am using the Student/Educational Revit 2014. How can I fix this?

Hard to say we don't have enough information from you. Property lines don't matter. The only thing that matters is the points elevations. If you only have a couple inches difference between your lowest point and your highest you aren't going to see a big difference (if at all) when looking at it from far away. You could test it by putting some points way below or above your other points to make sure you are doing it correctly.

If you add a section box to the view and it cuts your topo, you will get cut "sides" to your topography with earth hatch and that will help you see the slope.

what are the units of the drawing and is the contour the same units?
i.e. not a decimal point issue when inputting the point levels perhaps?

All of the units are in feet/inches. The elevation points range from 0" to 10" and the terrain appears completely flat on both the 3D view and the section view (see attached picture) .

how about posting the topo so we can see the level points and values.
we could then duplicate the plan on our computer and see if we get same issue.

I do not have a specific site for this project, so I do not have specific topography values. I've been using this program for a few months now and made all of my topography in the same way and never had this problem before.

This is not a problem because Revit is showing you exactly what you have.
First view - plane 3D, second view section box - left on for you to see.
