Intensity
Sets the intensity or brightness of the light. The maximum spotlight intensity
depends on the attenuation setting and the extents of the drawing. If
attenuation is none, maximum intensity is 1.
If attenuation is inverse linear, maximum intensity is the value of twice the
extents distance: the distance from the minimum lower-left coordinate to the
maximum upper-right coordinate. The default value for inverse linear is half
the maximum intensity.
If attenuation is inverse square, maximum intensity is twice the square of the
extents distance.
Position
Modifies or displays the X,Y,Z coordinate location of the light and its target.
Inverse Linear
Sets attenuation to be the inverse of the linear distance from the spotlight.
For example, at a distance of 2 units from a spotlight, light is half as strong
as at the spotlight; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
Inverse Square
Sets attenuation to be the inverse of the square of the distance from the
spotlight. For example, at a distance of 2 units from a spotlight, light is one
quarter as strong as at the spotlight; at a distance of 4 units, light is one
sixteenth as strong.
Modify
Temporarily closes the dialog box so you can use the pointing device to
specify a location for the light and its target. A vector connects the spotlight
location to its current target.
Enter light target < current >: Specify a point or press ENTER
Enter light location < current >: Specify a point or press ENTER
None
Sets no attenuation. Objects far from the spotlight are as bright as objects
close to the light.
Select Color
Displays the Select Color Dialog Box. To define the color of light, you can
select from the 255 AutoCAD Color Index (ACI) colors, true colors, and
color book colors.
