1 From the Sheet Manager menu, choose Settings to display the Settings dialog
box.
2 Click the Section Preferences button to display the Cross Section Preferences
dialog box.

Changing the Volume Calculation Method
You can choose which volume calculation method is used for plotting cut and
fill volumes on the section sheets.

box.

dialog box.
3 Under Volume Calculation Method, you can select the method for volume
calculation:
n
Select Average End Area to use the Average End Area method of volume
calculation. With this method, the average of adjacent cross section areas is
multiplied by the distance between them. The commands calculate all data
from the actual values, but the reported values are rounded to the desired
volume precision for display purposes.
n
Select Prismoidal to use the Prismoidal method of volume calculation. This
method is also known as the grid method. When using this method, a
regular grid is overlaid on the two surfaces. The elevations on both surfaces
are calculated at each grid intersection. The resulting face is then broken
down into two triangular prisms.
