This command generates a Mass-Haul diagram and displays it in the drawing file. A Mass-Haul diagram shows a cumulative total of cut and fill volumes along a horizontal alignment. The diagram is a tool for measuring how much material is being added to and removed from the design site.
Before you generate a Mass-Haul diagram, you must run the End-Area Volume command. When you do that, you select a set of cross sections, and within that set, you specify at least two cross-section surfaces. The results generated by the Mass-Haul Diagram command are based on the cross sections and surfaces selected when you use the End-Area Volume command. The End-Area Volume command generates an XML file that is required for this command. See End-Area Volume for more information in computing end-area volumes.
Interpreting a Mass-Haul Diagram
A Mass-Haul diagram shows cumulative cut and fill along a horizontal alignment. When graph is above the axis, there has been more cut than fill along the entire alignment up to that point. When graph is below the axis, there has been more fill than cut along the entire alignment up to that point. At stations where the graph reaches zero, the design contains an equal amount of cut as fill from the beginning of the diagram to that station.
You can determine from a Mass-Haul diagram if a specific station is in cut or in fill by the slope of the graph at that station. If the graph slopes upwards (in the cut direction) at a given station, the design is in cut at that station. Conversely, if the graph slopes downward (in the fill direction), the design is in fill at that station.
The top diagram shows existing ground (dashed line) versus proposed grade. The lower diagram is the Mass-Haul diagram.
