understanding Grading Groups
A grading group is a named collection of grading objects that enables you to
perform certain important functions with multiple grading objects simultane-
ously. For example, you can create a surface from a grading group or calculate
cut and fill values by comparing a grading group to a surface in the drawing.
understanding Grading objects and Sites
Like feature lines, grading objects must exist in a Civil 3D site. When two or
more grading objects occupy the same site, there is potential for them to inter-
act. There is also the potential for grading objects to interact with other feature
lines in the same site. This interaction can benefit some designs, but there are
cases where this interaction will cause the design to be incorrect. Therefore, it's
important to proactively manage sites while you're working with grading objects
and feature lines.
Creating Grading objects
You begin creating a grading object by launching the Grading Creation Tools
command. This opens the Grading Creation Tools toolbar (see Figure 17.10),
which is similar to the Alignment Layout Tools and the Network Layout Tools
toolbars that you used in previous chapters. Like those toolbars, the Grading
Creation Tools toolbar provides the commands to configure your design, create
new design objects, and edit those objects.
