Surfaces which should yield one single minor contour don’t show any contours

In Civil 3D 2009, any surface which uses a style under which only one minor contour would show for the entire surface, no contours are shown.

This is very difficult to explain verbally, but the image below illustrates the problem.

Workarounds:
Create a temporary style which shows major contours at the interval that you would typically show minor coutours with. Make those major contours the same color/layer/linetype as your regular style’s minor contours. Apply the new temporary style to the problematic surface.

Status as of Civil 3D 2009 version 2: Still reproducible
Status as of Civil 3D 2010: Resolved
