Sun Angles can display their date and time in
floor plan view and can also produce sun
shadow polylines in floor plan view. Both

the exact position of the sun in the sky in a
particular location and at a specific date and
time. This position and time information is
specified in the Sun Angle Specification
dialog; the date format is derived from your
operating system settings. See “Earth Data A Sun Angle and shadows for Coeur d’Alene, ID
