In Chapter 17, “Designing New Terrain,”
you experienced a few examples
of using the AutoCAD
®
Civil 3D
®
software to design new terrain in the form of
lot grading and pond design. With more time, you would have completed the
shaping of all the lots, resulting in a grading design for the entire project. Now
that all the major grading design components are complete (roads, lots, and
a pond in this example), it's time to combine them into one complete design.
Once you have done this, you can analyze the design to ensure that it meets
several additional design and construction requirements. This analysis may
result in the need for an adjustment to the design, at which time you'll begin
an iterative process: design, analyze, adjust, design, analyze, adjust, and so
on. You'll repeat this cycle until the design is the best that time and resources
permit. When the design is optimized, you can then provide annotation that
provides the necessary information for the contractor to build your design for
the land's new shape.

Combining Design Surfaces
In Chapter 17, you created a pond design that resulted in a surface represent-
ing the shape of the pond. You also performed some lot grading; and if you had
continued working on the lot grading for a few hours, you eventually would
have finished all the lots, creating a surface that covered nearly the entire
