I am a civil engineer working on roads and use autodesk civil 3d. However, please indicate the following:
1. Where the road is the road. A Google earth kmz file coordinates can help.
2. How long is the road?
3. What is the lane widths?
4. What is the pavement structure design?
5. What is the primary use for the road.
6. Is this a scoping, preliminary stage or detailed design stage?
