Is it possible to weed contour lines displayed in a surface based on the slope? I am having an issue plotting construction plans due to steep cut slopes and flat adjacent areas. I have several cuts ranging from 33%-50% adjacent to flat areas around 1%. Due to the drawing scale required by the client and the .2FT and 1FT contours required to detail the flat areas, my steep cuts appear as dark hatches due to the tight contour lines. Any suggestions?
