Hello All,
Thank you for welcoming me into your community. I am in quite a pickle. I have to create a 3D topographic map from survey data, using polylines and interpolation. The contour interval is 2'. The survey data is already in a dwg file (elevation and postion). I am using AutoCAD 2010. My knowledge in AutoCAD is really small and I really don't know how to start. Later in the project I have to cut a road in the topograph and measure the amount of soil I have removed. It is due this evening and I don't know what to do. Please help. Thank you in advance for your response
