We recently updated to Civil 3D 2009. When adding Feature Lines to a surface, I usually set the Mid-ordinate Distance to 0.1 to generate smooth contours. In C3D 2008, this work great but not so great in C3D 2009. I’ve also adjusted the Distance in the Supplementing factors along with the Mid-ordinate Distance. Is there another setting I need to adjust to generate smooth contours without adding elevation points along the Feature Lines? I’ve attached tow photos showing the settings and results.
