CROSS-SECTION
STREAM computes earthwork quantities the way road and survey engineers do — by cross-sections. Draw an axis on the terrain, set the section interval, and STREAM slices a section out of the DEM at every station, measures each cut/fill area, and sums the volume between sections into a total.
Cubature is the volume of earthwork computed from cross-sections taken at regular stations along an alignment. The area of cut and fill at each section is measured, and the volume between sections is summed (average end-area).
It is the standard method for roads, canals, channels and trenches, because it produces a checkable, station-by-station quantity table.
Set the axis with two clicks; STREAM cuts a section from the DEM at every station, so the ground line always matches the real terrain.
The cut and fill area of each section is measured automatically at the interval you choose.
Get a clean station-by-station table of area and volume, with total cut and fill (average end-area).
Export the cross-section drawings as DXF, ready to drop into CAD.

Yes. STREAM exports the cross-section drawings as DXF for CAD, alongside a station-by-station cubature (volume) table.
Road, canal, channel and trench earthworks, site grading and quantity takeoff — anywhere station-based cubature is used.
