How do you create a surface in Civil 3D from 3D polylines?

Can you create a surface from polylines in Civil 3D?

You have successfully not only added in polyline contours, but you have also reordered the surface operations so that Civil 3D builds the surface in the correct sequence. Civil 3D makes it very easy to add in many different types of data to a surface; polylines is just one of them.
