I'm making an escape room. It's nearly done. I'd like to document what's where, to help with future maintenance. Are there any good tools or even just approaches to documenting the locations of wires and electronics in a suite of rooms, when the stuff's not on the floor, but on/in the walls and ceiling?
Ideally I'd like to somehow visually depict stuff like "The ???? is mounted 4' up, and is driven from a breakout board on the other side of the same wall, hidden behind ???? ?? ? which has a cable behind the wainscoting about 3' up over to the microcontroller which is stuffed behind the portrait of ??????. Its cable to the control room goes along the trim, to the corner, where it goes up to the ceiling" etc.
