Does anyone know if it is possible to clip a terrain model in OpenRoads Designer to a contour line or ever create a new terrain clipped to an existing terrain's selected contour line? Since contour lines are not graphical elements, I cannot select it as a boundary or copy the selected contour line into my file as an element.
Use 'Terrain > Analysis > Analyse Point' to show a dynamic contour at the cursor position. Left click to place the dynamic contour as an element in the DGN. This element should be usable for use as boundary etc. To snap to required contour (to ensure the Z value is correct) hold CRTL+Shift to force AccuSnap on.
