To turn on all lighting group layers so that lighting group area boundaries and labels are displayed on the drawing, go to
Ribbon: DM Electrical->Lighting Groups-> 
Turn Lighting Group Layers On
Pulldown Menu: DM Electrical->Lighting Groups->Turn Lighting Group Layers On
The layers that the lighting group area boundaries and labels are inserted on will be turned on.
By default, these layers are non-plotting and do not have to be turned off before plotting.
