I have been asked to generate a 3D model of our workshop which I need to generate a hill and a tunnel inside.I have seen lots of ESRI and others tutorial online and they all tutor how to create surface 3D model but I couldn't find any sample of creating underground Model!
Can you please let me know how I can generate a 3D model of a Tunnel inside a hill? I have the tunnel information on CAD file and I just convert it to shapefile as a polyline
but I have no idea how I can assign values like (Height, Slope, Elevation, or any other required values!)to a line?!
Can you please kindly let me know how I can do this or introduce me a sample or tutorial of Underground(Geology) 3D mapping in ArcGIS?
