There are several options for site modifying. You can add extra source data into the site model to modify it, and you can use site modifiers like roads (good for roads and paths), pads (good for flat or uniformly sloping areas), hardscapes, landscape walls, 3D polygons, and stake objects.
Each site modifier follows the same strategy. The site modifier has a 3D part the will change the site model and a boundary. The Boundary is a planar shape that defines how much of the site model will be affected. The Boundary is flexible and it allows you to choose the extent of the site modification. If the boundary is close to the site modifier, you will have a steep slope. If the boundary is a long way from the site modifier, you will have a gentle slope.
