I'm just starting, and I have not been able to find a solution to my problem. I need to be able to measure volume in cubic feet, and I have not been able to figure out how. In the reference pane I have used the convert to select the the correct projection State Plane ND South US feet, but when I measure for surface area and volume, all I get is meters. In the user manual it specifically says the output is in meters. Is there a way to measure in imperial units?
