Surface from the sections
Every point of a layer placed on the plan with the horizontal alignment – chainage and offset become easting and northing – to make a surface (TIN) and contours from the cross sections.
The ground layer makes the existing surface; the design layer (formation, template result) a design surface to compare with it – in Surface volume, for instance.
