LightsKeyCreator \ Create \ Light \ Lights
The features available from the Create>Lights pull-down and Advanced Modeling>Create>Lights palette submenus allow you to define and place reference entities that can be used to create realistic lighting effects in your drawings.
NOTE: Once placed, light entities can be edited and moved using the Edit and Move functions. However, only the light source may be moved. That is to say that the location of local lights and spot lights may be moved, but not the direction of lights.
