How should I model a 4" thick sidewalk that has a complex slope and that needs to show in section? The sidewalk slopes in 2 directions and the slope varies as it wraps around the block and turns into a courtyard.
There is a below-grade parking structure so the wall sections that go below the sidewalk.
All i have to start with is the 2d cad civil plan which give me spot elevations for where the sidewalk is.
Thank you very much for your help.
