From the initial planning of an event, the basic information is taken and put into a CAD (Computer Aided Design) program.
	Within the program all the lighting elements can be laid out in 3D. The lighting can then be pre-programmed in the computer and all the specifics; such as power, cable lengths, truss, etc. can be worked out.
	The pre-programming ensures that when the rig is finished and lights installed - the fixtures are ready to work.
