Hi,
Only in very artifiical situations.will you get similar contours.
Particularly if the polylines include arcs
Building a DTM from contours is nearly always the least accurate way of
doing it, as the contours are already a approximation of the surface and
normally cannot reflect the real shape of the surface as well as the TIN
model.created and whose contours are displayed by Civil 3D.

Hi
When you create surface from AutoCAD polylines (drawn as contours) the
surface contours hence generated donot exactly overlap the AutoCAD contours.
Is there any option for this.
