The purpose of a subregion is to match two surface materials so any change in elevation or lateral movement is reflected in both regions. You need this ability for walks and most roadways. When you divide the toposurface into subregions, you give yourself the freedom to manipulate two different materials within the same datum. Another benefit of subregions is that the file size remains as if there was still one toposurface. If you were to split the surface every time you needed a path or a roadway, your file size would bloat.

The objective of the following procedure is to create a walkway path using the subregion command. Follow along:

1. Go to the Site plan.
2. Zoom in on the east entry.
3. On the Massing & Site tab, click the Subregion ...
