Digital Elevation Modeling (DEM) refers to modeling a site plan and related amenities onto a 3D terrain surface. This chapter provides an overview of the entire process. The reviewed process can be applied to any size of terrain and site model, from residential lots to large‐scale plans. TopoShaper is an additional extension that can help generate a grid or mesh terrain, and it is available through the SketchUcation Plugin Store. The typical approach to generating a DEM starts with a CAD file that includes at minimum contour or point data with Z elevations or values. The chapter demonstrates the basic dataset and includes contours, a road, a house, walls, steps, and vegetation. Two general types of terrain can be created in SketchUp and other 3D modeling programs: a Triangulated Irregular Network (TIN) and mesh, a terrain surface composed of grids.
