Hello, I'm looking for some help in integrating new topography into existing contour lines and I have no idea how to go about doing it. I don't know how to work Civil 3D or even if that's what I need to achieve this. I'm willing to pay someone to do this for me or to help me figure out how to do it. I will attach a PDF of the site I'm talking about. In the end I want to be able to generate a surface using the contours and have it include the proposed site modification. I have the existing contour lines at their proper elevations but the new grade modifications is just a flat dwg.
Hope someone can help and I apologize if this isn't the right place to ask this
