Hi,
I am trying to draw/create my own contour map from scratch. I am going to draw chemical concentration contours on a site rather than elevation contours. Can anybody please help and give me info on how to do this? Thanks.
I am assuming you already know how to interpolate contours from sample points and only need help with the AutoCAD part. I mean, draw a line from one sample point to it's nearest neighbour, calculate the positions contours will intersect the line. When you have done this for all sample points, draw polylines connecting the points on the same concentration contour.
