Toposurface Subregions
Toposurface subregions are areas that you sketch inside existing toposurfaces. For example, you can use
subregions to draw parking lots on a graded surface, roads, or islands. Creating a subregion does not result
in separate surfaces. It merely defines an area of the surface where you can apply a different set of properties,
such as material.
To add a toposurface subregion:
1 Click Site menu
➤
Subregion, or click Subregion on the Site tab of the Design Bar.
Revit Architecture enters Sketch mode.
2 On the Design Bar, click Lines, and use the sketch tools to create a region on the toposurface.
3 When you finish a subregion, click Finish Sketch.
After finishing the subregion, you can select it and click (Element Properties) to change its material.
The following image shows a toposurface that has a toposurface subregion, shown in gray.
Splitting a Toposurface
You can split a toposurface into 2 distinct surfaces and then edit those surfaces independently. After splitting
a surface, you can assign different materials to these surfaces to depict roads, lakes, plazas, or hills. You can
also delete entire portions of the toposurface.
