Create a proposal, sketch new features, and export the result.
Once your base model is in place, you can create any number of proposals to try out or present design ideas.
In this lesson, you will draw a new road that goes under a hill. You will modify the road, splitting it into two sections. One section will go along the open terrain and the other will become a tunnel under the hill.
You will style the road, adding shrubs along the green space.
Export the resulting road to IMX format, which you can import into Autodesk Civil 3D.
