The SiteNet programs build triangulation surfaces, apply surface
adjustments, calculate volumes and report material quantities.
Drawing layers are organized by target surfaces: design, existing
or other. Polyline perimeters are used to define the site boundary,
subgrade areas and topsoil areas. Once the layers and perimeters
are setup, the surfaces are created by the Make Existing/Design
Surface commands. Then there are commands to inspect the surfaces
and report volumes and material quantities. See the Takeoff section
of the Construction chapter of the manual for specifics on each
command.
