Using Grading Objects and Daylighting Commands | 125
■ Finished grade labels: Labels surface elevations.
■ Stratum: Defines a group of two surfaces where the differences between
the two surfaces can be used to calculate volumes and elevation.
■ Pond models: Used in planning stormwater management and in
hydrology calculations.
After you have created all finished ground grading data, you can then create
a finished ground surface.
NOTE It is recommended that you create new layers for the finished ground
data. Before you define the surface data when creating the new surface, you can
freeze or turn off all unnecessary layers. By using separate layers, it is easy to
select only the information for a specific surface. You can create separate layers
for finished ground points, contours, and breaklines, or place them all on the
same layer.
Using Grading Objects and Daylighting
Commands
You can create grading plans using either the Grading Object commands or
the Daylighting commands.
Using the Grading Object commands, you can:
■ Direct water ways between grading pads for a subdivision.
■ Add and update curb islands.
■ Facilitate “what-if” designing by creating interactive projects that are
easily updated.
Daylighting commands provide a backward compatibility that may be
familiar to many users.
Using the Daylighting commands, you can:
■ Design a parking lot that has a ditch.
■ Add step slopes to a design.
■ Provide updating flexibility to a large and complex design.
