1. 1 GRADING AND DAYLIGHTING  The Daylighting commands calculate slope daylighting from a polyline footprint to a surface.  A 2D or 3D polyline with elevational information is used to represent the footprint.  Additional vertices can be added to the polyline for increased daylight line sampling.  Based on the polyline footprint elevations and the assigned slope information, the daylight line is calculated at each vertex to a selected daylight target surface.
