Create Detla Terrain Model tool
Used to create a delta terrain model between a surface and plane or between two surfaces, which can then be used for Isopach contouring.
Found on the Civil ribbon in the Terrain Model group.
The Delta Surface tool creates a delta TM between a surface and plane or between two surfaces, which can then be used for Isopach contouring. The Z value in the delta TM is the difference between the two specified models or model and surface, rather than actual elevations. Any voids in any of the terrain models produces a corresponding void in the delta model (as the software cannot compute the difference in these areas).

||||||
Vertical Offset 1 | Vertical Offset 1 moves the first terrain model up (positive value) or down (negative value) by the offset distance, in terms of master units prior to processing the delta command. | ||||||
Vertical Offset 2 | Vertical Offset 2 moves the second terrain model up (positive value) or down (negative value) by the offset distance, in terms of master units prior to processing the delta command. | ||||||
To Plane | The elevation of the plane specified in terms of master units (feet or meters). | ||||||
