Precircuiter is a must-have tool for any master electrician who's tired of precircuiting lighting plots by hand. Just open Vectorworks instrument data, click the "assign" button, and watch as Precircuiter pairs the lights on your plot to the closest receptacles available. Precircuiter takes the most efficient route, saving you cable and time spent hanging lights. Caveats: - Precircuiter needs to know where outlets are. These must be added to your Vectorworks plot as lighting instruments with "Power" as their device type. This only needs to be done once and saved as part of your venue's template. - Precircuiter doesn't support flyspaces (yet), or any venue where grouped receptacles travel in a bunch.
