Get PriceIm trying to draw a surface from scratch, I have no data from survey, no points, etc. How can I draw contours? I've been reading that contours are 3d polylines, but I was wondering if you somehow can draw several 2d polylines which would be your contours then give each line .
Get PriceJul 06, 2015 · Let's say, from the black points, the first contour line is 10 meters so all black points should be covered within 10 m i.e. from the point to the first contour is 10 m. And then next distance between 25 m, 55m, and 75 m contour lines should be exactly 25 meters (interval).
Get PriceMay 18, 2018 · To find the elevation interval between contour lines, divide the elevation difference between index lines by the number of contour lines from one index line to the next. In the example above, the distance, 200, is divided by the number of lines, 5. The contour interval equals 200 ÷ 5 = 40, or 40-foot contour intervals.
