Is there a technique for creating topographical landscape drawings using the
contour lines on a typical civil engineering drawing? I can easily convert
the contour lines into closed poly-lines and give them elevations relative
to each other. However, I have not been able to use any of the Autocad 14
surface features to connect the contour lines make a 3-D landscape drawing.
Any ideas?

The simplest (but not very good) way is to use Rulesurf to join
adjacent plines. This does not give particularly good results but it
just may be enough for you. Otherwise you will need add-ons which
others here will know about.

Put the "at" in the gap.

Plain Autocad is ill equipped to create a surface from pline/elev data that is
viewable. Using an add-on, like Land Desktop (or others), you can create a
digital terrain model, then import that into your drawing as 3d faces. 3d faces
can have textures applied and rendered, or they can be shown as shaded objects.

As Karl said, not with AutoCAD alone. Take a look
at http://www.carlsonsw.com/dtmcontour.htm for an
example of what a 3rd party add-on can do for you.
