Use the Volumes Dashboard to set EG as the base surface and FG as the comparison surface. The FG surface is made up of pasting the Alignment surface onto the EG surface. Shown below is the Final Grade surface (FG) and the Existing Grade surface (EG). Green for fill and red for a cut.Ĭreate a new volume surface from existing surfaces. All that is then required is to create a surface style that displays elevations in differing colours. A positive value indicates a fill, and a negative value indicates a cut. It appears based at the zero elevation as a reference meaning no cut of fill. The cut and fill surface that is created from a cut and fill analysis is a volume surface that reports the volume difference between two surfaces.
A very interesting question was posed to me: how would one display a cut and fill a surface in colour, differentiating between cut and fill with separate colours? It is easier than one would expect.
