Not sure what issue you are running into or how much you already know, so I'll start at the beginning with apologies if you know some of this.
Note that label legends will only attach to lighting symbols that have been converted to Instruments.
There are actually 3 steps to using Label Legends
1) Create the LL in Spotlight - Label Legend - Label Legend Manager - Edit Fields, choosing what info you want in the legend - I.E.
Channel,
Dimmer,
Unit Number, Color,
Template would be obvious choices. In the edit section, select Right Read for all, so that the text of the legend rotates with the
fixture orientation. I generally find I need a lot of different legends, depending on the type of
instrument and the expected orientation. Thus a S4 25/50
zoom has a different legend then an S4
Par, as the units are different sizes. Also in edit you can choose a "container" for the piece of info., thus a
channel would have a Circle Container, while a
Dimmer might have a Hexagon container. AS BTW, containers are in the Resource Browser. You can create your own and save them to the Container folder. My typical document might have 15 to 20 LL's, for assorted units in particular positions. They are easy to copy. If you create a legend for a SR
box boom position and want the same legend for SL, just reversed, simply create and save the SR, then go to Resource Browser - Resources - Label Legend Folder, select the SR Box legend, right click and duplicate with a new name. Then go back to the Label Legend Manager - Edit
Layout, choose SL, select all and Modify - Rotate - Flip Horizontal.
2) Configure the
layout of the Label Legend in the Edit
Layout section of the LL Manager. Here is where you choose where the assorted data attributes will reside in proximity to the
fixture symbol. The Color would go near the
lens, the
Dimmer near the rear of the
fixture,
Channel near the
dimmer,
unit number inside the fixtures,
etc... for an
instrument pointing Upstage/
Downstage,
etc... IN the
Layout section you can change the default
instrument object to one appropriate to the
fixture type the legend will be assigned to, as well as selecting text size of the data attribute, whether or not the symbol and/or text will have solid or no fill,
etc....
3) Then assign the legends to the fixtures. Fastest method is in the Find and Modify, "Find all Light whose
Instrument Type = S4-36, then choose Assign the "XX Label Legend to them. Repeat for all units.
