Sun and Sky
If you select

dialog box is displayed. See Figure 17-28.
AutoCAD uses the settings in this dialog box to simulate the sun in the sky. This dialog
box has a preview tile at the top and the General,
Sky
Properties, Horizon, Advanced,
Sun disk

Sun Angle
Calculator,
Rendered Shadow

Geographic
Location
categories. The settings in these categories were discussed earlier in the Sun
Properties Palette section in this chapter.
Once the sky is set, pick the
OK
button to close the
Adjust Sun & Sky Background
dialog box. Then, save the view, set the view current, and pick the
OK
button to close
the
View Manager
dialog box.
Changing the Background of an Existing View
To change the background of an existing named view, open the
View Manager
dialog box. Select the view name in the
Views
tree on the left-hand side of the dialog
box. Then, in the
General
category in the middle of the dialog box, select the
Background
override
property. See Figure 17-29. Next, pick the drop-down list for the property and
make a selection. Picking
None
sets the background to the AutoCAD default back-
ground. Setting the property to Solid, Gradient, or
Image
opens the
Background
dialog
box, where you can make settings for that type. Selecting
Sun & Sky
opens the
Adjust
Sun & Sky Background
dialog box. Picking
Edit
opens the
Background
or the
Adjust
Sun & Sky Background
dialog box with the settings of the current background. Once
the background type has been changed or the existing background edited, pick the
OK
button to save the view and close the
