When drawing units are set to imperial, the software divides the volume output by 27 (the conversion factor between cubic feet and cubic yards). When drawing units are set to metric, the volume output is reported directly in cubic units. If you create a drawing using feet for the units, you can generate volumes to report in units of cubic feet by changing the drawing setup units to metric prior to calculating volumes. After the volumes have been calculated and reported, you can change the drawing setup units back to imperial.
To change the drawing setup units:
Select the Projects menu > Drawing Setup.
In the Drawing Setup dialog box, select the Units tab.
Under Linear Units, select Meters.
Choose OK to close the Drawing Setup dialog box.
Select the Projects menu > Drawing Settings to display the Edit Settings dialog box.
Under Program, select Land Development Desktop or Autodesk Land Desktop (the name of the selection depends on the version of the software you are using).
From the Settings list, select Volume Site Definitions and then choose Edit Settings.
In the Volume Site Settings dialog box, under Volume Labeling, modify the suffix to indicate cubic feet.
Choose OK, and then choose Close to close the dialog boxes.
Calculate the surface volumes and display the report. Units should display as cubic feet.
Change the drawing setup units back to feet before continuing to work in the drawing.
