Where it goes on stage
Put it where it will really stand, not where it is convenient to draw. Risers sit upstage centre or upstage left of the kit. Stairs face the side the performers enter from, and truss goes where it can be flown or ground supported without fouling a sightline. Stageplot Pro keeps every icon to scale, so the spacing you draw is the spacing the crew builds.
What the crew needs to know
The detail that saves a phone call. Give riser dimensions and height in the plot notes. Icons show position; numbers settle the build.
On the input list
Truss Lift is not an audio source, so it adds no rows to the input list. It is there to make the drawing accurate: it sets the physical geometry every other piece of gear has to work around, and the channel count stays clean because nothing silent is padding it out.
Console exports
Channel names travel with the plot. Export a scene file for an X32, M32, or Wing, or a channel name CSV for dLive, Avantis, SQ, DiGiCo, and Yamaha CL and QL. See the console guides.
