Name the style Flood in the Information Tab, and on the Display tab, uncheck Slopes and set the Visible for User Contours to on. relating to this issue i am also trying to converting a polyline to a contour by known fixed elevation for exaple if i have a plane surface data but there is a pit in somewhere which i have its border and inside elevations (some level points) so i have first to indicate the nearby outside points to give the same elevation of main plane surface i have after i can handle with the surface to calculate volume e.t.c. In general, the density of spot elevations should be greater where terrain elevations vary greatly, and sparser where the terrain varies subtly. Kevin Sabo (personal communication, Winter 2002) remarked that "If you were unfortunate enough to be hand-contouring data in the 1960's and 70's, you may at least have had the aid of a Gerber Variable Scale. I've never used the USGS maps though since my workflow is just for prelim studies of a project so they don't need to be perfect. In case of using Borders & Contours, after playing the option, we have this: If you place Borders & Contours & Slopes it displays the contour map with a colored slope. How to create contours with AutoCAD Civil 3D, Tweets de https://twitter.com/geofumadas/lists/top40geofumadas. Navigate to the location where you saved the contour lines drawing.
