After a light has been
placed in a scene the position and target can be modified.
The
light, which is represented by a light glyph, can be repositioned
after it is placed in the drawing. The light can be moved and rotated;
the target can be modified. When the light glyph is selected, grips
are displayed.
By selecting the light
with a right-click, a shortcut menu is displayed that provides the
following options for adjusting the placement of a light:
- Move. Activates
the MOVE command. Used to change the position of the light.
- Rotate. Activates
the ROTATE command. Used to change the orientation of lights. In
addition to shortcut menu access, you can use ROTATE, 3DROTATE,
and ROTATE3D commands.
- Flip. Rotates
the target of the light in the opposite direction.
NoteRotating a targeted
light is useful for aligning the area shadow region appropriately.
Also, the orientation of the area shadow light is reset when the position
or the target of the light is changed.
Location (Point Lights
and Spotlights)
You
can use the grip labeled Position to move a point light or a spotlight,
or you can set the location in the Properties palette. The Position
grip moves the light but does not change the target. To move both
the light and its target, drag the light glyph itself.
