GRADING AND DAYLIGHTING Ø The Daylighting commands calculate slope daylighting from a polyline footprint to a surface. Ø A 2 D or 3 D polyline with elevational information is used to represent the footprint. Ø Additional vertices can be added to the polyline for increased daylight line sampling. Ø 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. 1
