Designing New Terrain

With the completion of the pipe networks, the design of the road is nearly finished. It is now time to move on to the next area of the design, which is the shaping of the land, or grading, of the adjacent areas. In “Designing in 3D Using Corridors”, you designed a 3D model of the road in the form of a corridor. This model will serve as a basis for much of the adjacent design that will take place, such as the shaping of individual lots and grading within the stormwater management area.

Each of these areas has unique design objectives. The individual lots will be shaped so that homes can be built on them without requiring significant earthmoving. The stormwater management area will require a pond to serve as a means of collecting and treating the stormwater runoff. These designs will serve as opportunities for you to study the two primary grading tools contained within the AutoCAD® Civil 3D® software: feature lines and grading objects.
