During the Civil 3D Class we started with a set of data points in various forms and then practiced: 1. importing them 2. Creating starting surfaces 3. Applying modifications to them to plan the creation of roads, sewage systems, plumbing systems, and neighborhoods.
I ended up exporting the generated surfaces to .stl files and 3D printing them for additional visualizations after the class had completed.
