■
You can create a range map that displays the cut areas in one color
and the fill areas in another.
■
You can create cut/fill contours on a volume surface. The volume
surface Z value is the cut/fill depth instead of an elevational value.

Creating a 3D Map to Present Elevation
Conditions
After you create a surface, you can use several tools to help you
visualize the surface in 3D. For example, you can use the Elevation
and Slope range commands on the Terrain
➤
Surface Display menu to
insert 3D faces into the drawing. These commands place surface
triangles that fall within a defined elevation or slope range onto
specific layers. You can then make each layer a different color. For
example, you can put any portions of the site that fall within an
elevation range of 100' to 105' on a blue layer to visually distinguish
the elevation range.
