The topography does follow the points, however the countour line maynot. If your settings are correct it should come very close. Revit has problems with swales. but if you add enough points along curves it follows them quite well in my experience. However I very rarely input my on points, its easier to draw the countour lines, move them to the right elevation, export to acad and re import, then use that import to create the topo surface from. Or in most cases we have a civil drawing that allready has the contour lines at the proper elevation and you use that.
