How do you extrapolate a surface in Civil 3d?

It’s available through the surface smoothing command. Basically what you do is select existing TIN points in a region reasonably close to the area you want to expand the surface into. Try to limit this region to points that make sense for predicting the elevations of the new area.

How do you define a surface in Civil 3d?
