Azimuth is the bearing angle (180 degrees at mid-day). Altitude is the vertical angle between
the horizon and the sun, as measured with a sextant. Altitude changes from day to day through
the solar year.
3 To orient the sunlight along the orientation of the view, select Relative to View.
This option provides consistent shadow graphics on a series of elevations, regardless of their
actual orientation.
To orient the sunlight along a True North-South trajectory, clear Relative to View.
4 To specify the level to be used for shadow display, select Ground Plane at Level, and select the
level.
When you select Ground Plane at Level, Revit Architecture casts shadows on the specified level
in 2D and 3D shaded views. When you clear Ground Plane at Level, Revit Architecture casts
shadows on the toposurface, if one exists.
NOTE This option does not affect shadows in rendered images.
5 To test the new sun and shadow settings, click Apply.
6 When you are finished setting up the solar study, click OK.
Specifying Settings for a Single-Day Solar Study
A single-day solar study is an animation that shows the movement of shadows at a project location during
a defined range of time on a specific day. For example, you can track shadows from 7:00 AM to 7:00 PM on
June 22.
Changing the place allows you to set up solar studies for the same building model in different locations. For
example, if the same retail store will be constructed in Los Angeles and London, change the Place setting at
the project level, and then export a solar study for each city location.
Use this procedure after performing the initial steps to create the study .
To specify settings for a single-day solar study
1 On the Sun and Shadows Settings dialog, click the Single-Day tab.
2 Select a solar study from the list.
3 To change the place, do the following:
a For Place, click .
b On the Place tab of the Manage Place and Locations dialog, select a city.
c Enter values for Latitude and Longitude if you need precise solar study information, or
accept the predefined values if you want a close approximation based on the nearest city.
NOTE If you enter values for Latitude and Longitude, no value displays for City. When you click
OK, the Place value in the Sun and Shadows Settings dialog is User Defined.
d If you want Revit Architecture to calculate whether to use daylight savings time, select
Automatically adjust clock for daylight savings changes.
e Click OK.
4 In the Sun and Shadows Settings dialog, for Date, specify the date for the solar study.
5 For Time Range, select Sunrise to sunset, or enter a time range for the solar study.
