Performing a Volume Calculation
One of the most powerful aspects of Civil 3D is having instant feedback on your design iterations. Once you create a preliminary road corridor, you can immediately compare a corridor surface to existing ground and get a good understanding of the earthwork magnitude. When you make an adjustment to the finished grade profile and then rebuild your corridor, you can see the effect that this change had on your earthwork within a minute or two, if not sooner.
Even though volumes were covered in detail in Chapter 4, “Surfaces,” it is worth revisiting the subject here in the context of corridors.
