If the expense and/or learning curve of Civil3D is too much, then DotSoft's MapWorks add-on for plain AutoCAD can do this. First I used it's Reconstruct TIN to turn the 3dFaces into a TinSurface, then I used Create Contours to generate contours. It could also be used for contours ...

If you don't have 3d faces or the drawing is 2d you could also add an elevation to the polylines representing the contours and add them to the contours definition for the surface. This method would not be as accurate as using the 3d faces though, it's a last resort if the drawing ...
