|Define contour line intervals, select section cut material, and specify the poche depth for topography elements.|
|In a site plan or a 3D view, create a topographical surface by picking points, importing 3D data, or importing a points file.|
To provide the proper context for the building in relation to the building lot, specify True North in relation to Project North.
|Sketch property lines, or create them using survey data.|
In the site plan, add a building pad to the toposurface. Then modify the structure and depth of the pad.
|Grade the toposurface of the building pad, indicating changes to existing contours.|
|Define existing roads and other site elements with toposurface subregions. Add placeholders for parking lots, service roads, and sidewalks. You can refine these elements of the site design later.|
|If you will retain existing trees or other site components, add them to the site design.|
