When you select a time interval, Frames displays the number of individual images that the solar
study animation will contain.
7 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.

Specifying Settings for a Multi-Day Solar Study
A multi-day solar study is an animation that shows the impact of shadows at a project location at a specific
time of day over a defined range of days. For example, you can view shadow patterns at 2:00 PM every day
from January 1 through March 31.
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 create a multi-day solar study
1 On the Sun and Shadows Settings dialog, click the Multi-Day tab.
2 Select a solar study from the list, or select the default: Multi-Day Solar Study – User Defined.
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 start date and end date for the
solar study.
5 For Time, enter the time of day when the solar study is to show shadows for each day.
6 For Time Interval, select the amount of time to elapse between each image in the animation.
When you select a time interval, Frames displays the number of individual images that the solar
study animation will contain.
