Provides options for controlling the light from the sun.
Activate
Uses sunlight in the current scene.
Intensity from 0 to 1
Controls the intensity of the solar light. The default setting is .15. Use this setting to increase the brightness of the overall model.
Color
Displays the current color of the solar light. We recommend setting this control to white (RGB 255, 255, 255).
Edit
Displays the Color dialog box, allowing you to choose an alternative color for the solar light.
Cast shadows
Generates shadows from the solar light.
Latitude
Specifies the North/South position of the model's location in degrees. This position includes both a numerical value and a qualifier, either North or South. You can type values in these fields or use the Zone, Map, or Cities buttons to pick the model's latitude.
Longitude
Specifies the East/West position of the model's location in degrees. This position includes both a numerical value and a qualifier, either East or West. You can type values in these fields or use the Zone, Map, or Cities buttons to pick the model's longitude.
GMT offset
Specifies the difference between Greenwich Mean Time (GMT) and the time at the model's location. You can type in a value or use the Zone or Cities buttons to pick the correct offset.
Zone
Displays the Time Zones dialog box, which allows you to choose the GMT offset by picking a zone's region or description from a list. By default, the first instance of the current zone is selected. For more information, see Time Zones Dialog Box.
Map
Displays the World Map dialog box, from which you can choose the latitude, longitude by picking a location from a world map. For more information, see World Map Dialog Box.
Cities
Displays the Cities dialog box, from which you can choose the latitude, longitude, and GMT offset by picking a city name from a list. The nearest city to the current latitude and longitude, based on a rough distance estimate, is selected by default. For more information, see Cities Dialog Box.
Date
Specifies the date for calculating how the sun should appear in the model. The default date is your computer's time when you first created the project database, for example, the date when you first opened the project in Smart Review. You can change this date by clicking the down arrow and picking a new date from the calendar.
Time
Specifies the time of day for calculating how the sun should appear in the model. The default time is the computer time when you first created the project, for example, when you first opened the project in Smart Review. You can modify this time by clicking the up and down arrows.
Daylight savings
Specifies whether or not the specified time is daylight savings time.
Use vector
Locks the position of the sun to a specific vector, rather than calculate the vector from the latitude and longitude values. When this box is checked, the options under location are not available. When this box is not checked, the values in the longitude and latitude boxes feed the X, Y, and Z coordinates and angles on the Solar Vector dialog box. However, changes made to these coordinates on the Solar Vector dialog box are not reflected in updates to the Latitude and Longitude fields. For more information, see Solar Vector Dialog Box.
Vector
Displays the Solar Vector dialog box, which allows you to lock the sun to a certain vector. This option effectively mimics the IGDS/MicroStation default sunlight.
