There are situations where users of n4ce may wish to carry out a design of a surface without the need to introduce or remove materials from site. In essence to balance cut and fill quantities.
This exercise deals with such a situation and introduces you to two possible solutions. One using a trend surface to balance offsets but not necessarily to produce a horizontal plane surface or balanced quantity and the other to generate a horizontal plane with balanced quantities, making allowances for bulking factors, if required.
The situation is complicated since the required outline of the preferred surface (magenta) does not fall wholly within the original ground surface (triangles). We will use tools that are available in the Designer edition of n4ce.
