Summary: This plug-in adds several light manipulation commands in a new menu to Rhino V4
Lights in Rhino do not allow a great deal of control for positioning. These utilities add some commands that you may find useful for this.
There are some for rectangular lights (the plug-in calls them area lights for now) and some for spotlights.
Rectangular lights are the most difficult to use in Rhino so this plug-in lets you make some special ones that have handles and some commands to manipulate the handles. See below.
Unzip to a convenient location, then drag and drop the Light_Utilities.rhp file onto a Rhino 4.0 window to install it.
The above work only on lights made by the first command, AreaLightPlace.
The AreaLight manipulation tools are very much a prototype and fairly fragile. Please be sure not to delete the points (handles) that are grouped with the lights.
