This tech tip explains the new enhancements made to the Generated Contours feature.
In previous versions of Civil Designer only one dtm surface could have generated contours. This has been improved.
Generated contours are now stored on a per-surface basis. In this way you don't have to redo generating contours each time when contouring more than one surface.
Terrain Menu > Generate Contours
Generate contours for surfaces 1-3.
Once the contours have been generated the generated contours for the various surfaces can be selected.
