This function allows you to see the direction that a luminaire is aimed. To use this tool, go to Radiance—>Luminaires—>Show Luminaire Aiming. Select a luminaire as prompted by the command line. A red arrow will appear that shows the direction that the luminaire is pointing. To change the luminaire aiming, use the standard object rotation commands of the Graphic Editor.
In AutoCAD, the best way to aim a luminaire is through a series of rotations about the Z-Axis of the user coordinate system (UCS). First rotate your UCS such that the z-axis is parallel to the axis on which you would like to rotate the luminaire, for example "UCS, X, 90" will rotate the UCS about the x-axis of the current UCS by 90 degrees. Then type the "rotate" command and select a point on the surface of the luminaire.
