Hi Dave,
I've managed to do some testing now in Civil 3D and found that the software
does not create surface interpretations in the circumstances I described.
I've attached 4 screen grabs of the experiment which I think illustrate the
situation. The white line shown in the view with the contours is a hand
drawn polyline at a non integer value. The other starting polylines I drew
probably don't show in the screen grabs.
I guess I'm not surprised that this is the case. It would take some
seriously complex decision making to extrapolate levels into the area on the
right.
