When you are doing outdoor photometrics, you often do not want the foot candle levels to be displayed inside the building outline drawn with the light-obstructing objects. The extra 0’s both clutter the drawing and are included when calculating the statistics, resulting in incorrect values.

If the boundary is drawn using the “Insert Light-Obstructing Line” command, foot candle levels will appear inside the building.

If the boundary is drawn using the “Insert Light-Obstructing Rectangle” or “Insert Light-Obstructing Shape” commands and the starting elevation is 0, foot candle levels will not appear inside the building.
